Issues around sustainable development and renewable energy have grown in importance over the last two decades. Research and investment into wind, solar and energy storage have driven the growth of each of those renewable resources into billion dollar industries.

Except for the environment, no one stands to benefit more from the drive toward cleaner energy than consumers. Subsidies are a result of government sustainable development goals targeted at reducing global warming by offering consumers incentives for adopting renewable energy.

Thanks to various subsidies applied at state and local government level, you can reduce the cost of a solar installation by up to 50 percent. But what type of financial is available and how do you take advantage of it?

How Do Subsidies Work?

Subsidies cover the cost of purchase and installation of a renewable energy system or they pay out a tariff for the energy generated. This could be for:

• Insulation
• Glazing
• Wind
• Thermal systems like heat pumps or solar collectors
• Photovoltaic systems

These are just a handful of examples but subsidies can be applied to almost any building improvements that lead to more efficient energy consumption.

Subsidies for renewable energy in Spain are overseen by the Ministry for the Ecological Transition and the Demographic Challenge. Funds from the subsidies are disbursed at regional level by the respective Autonomous community, and by town halls at city level.

The funds cover work on residential, commercial, industrial, public administration and civic organization buildings. Individuals can be granted aid of between 30 to 40 percent while companies have a higher threshold of between 45 to 60 percent.

There are two ways in which subsidies are applied in Spain. These are through tax rebates or purchase and self-consumption subsidies.

Tax Rebates On Solar

Solar installations are subject to three different tax deductions. These are:

1. The Real Estate Tax (IBI)
2. Tax on Constructions, Installations and Works (ICIO)
3. Income tax deductions (IRPF)

Real Estate Tax (IBI)

This is a reduction on your real estate tax if you own a solar or other approved renewable energy system. At present it only applies to residences. Industrial, commercial and buildings like civic organization buildings are not covered.

The tax rate averages between 30 to 50 percent and is set by the municipality so it differs between cities. For example, in Bilbao the tax rate is 50 percent for seven years while in Saint Sebastian it is set at 10 percent for 5 years.

There are 760 municipalities in Spain, of which 415 have set an IBI tax rate. If you are looking into going solar you should make sure to check what rate is applicable to your property with regards to your city.

Going solar is a big step toward energy independence. Take our quiz and find out if you are eligible for state solar subsidies.

Tax on Constructions, Installations and Works (ICIO)

This is a tax credit applied on constructions, installation and work carried out on a building where getting a planning license or permission is required. It is an indirect tax and is applied whether or not the license has been granted.

Similar to the IBI, the ICIO tax rate is set by the municipality. It ranges between 30 and 95 percent. For example, in Malaga the rate is 95 percent for three years while in Toledo the rate is 30 percent for three years.

Income tax deductions (IRPF)

The personal income tax deduction is applied for when submitting your income statement. The maximum amount claimable is 20 percent on your income. The most important criterion for qualification are:

1. The applicant must be the owner of the property.
2. The installation should be carried out by a certified company.

Purchase And Self-consumption Subsidies

These are financial aid schemes that support the purchase or self-consumption of solar. They are applied at regional level by the respective autonomous community. The grants typically range between 30 to 50 percent. Below are some examples of how the financial aid schemes are structured in a few of the communities.

Andalusia

Under the FEDER scheme, Andalusians can apply for a grant of up to 40 percent of the cost of installation.

How Do You Qualify?

To qualify for the scheme:

1. The building or construction should have been built before 2017.
2. The applicant must be resident in Spain.
3. The property must be the applicants permanent residence.
4. Only one application per property.

Asturias

Asturias offers financial aid for isolated properties that require new connections that cost over €4,000 or where the distance from the connection point exceeds 200 meters.

Balearic Islands Grants

The Balearic Islands grants aid for photovoltaic self-consumption systems (energy you will use yourself) with a generative capacity of 99 kWp or less. The subsidy is capped at 50 percent for individuals, 40 percent for non-profit entities and 30 percent for companies and business organizations.

It pays out €1.80 per Wp for systems generating under 25 kWp and €1.50 per Wp for systems larger than 25 kWp.

Community of Madrid

In Madrid, the grants are awarded for photovoltaic, thermal, wind, geothermal and mixed systems. The amount is paid out for self-consumption on a percentage basis. Photovoltaic systems are entitled to 25 percent while solar thermal systems are granted 30 percent.

Each of Spain’s 17 autonomous communities has its own structure for determining eligibility and how the funds are disbursed. It’s also important to note that funds are subject to availability and in some communities the cutoff date for applications has been reached.

At the time of writing here are communities that had either already exhausted their fund or had reached the final date for submitting applications.

• In Aragon the application deadline had been reached.
• Cantabria closed for applications in November 2021.
• Applications for grants in Castilla La Mancha closed in October 2021.

Applications reopen when funds become available. It is important therefore to check with your regional body to see if they are currently taking applications. Solar is a smart investment especially if you can lock in a grant that reduces your costs.

Grants have a trend of decreasing as more solar systems come online. This is why you want to take advantage of them as soon as you can. Take our short quiz and learn if you qualify for a solar subsidy.

Why then are we not using more solar panels? Until recently the biggest obstacle has been the expense although this has started to change as solar panel prices fall. In this deep dive we critically examine whether installing solar for your home or business is worth it.

Over the course of this short guide, we will cover how solar panels work, what their pros and cons are, and the overall costs involved. By the end of this guide you will have a comprehensive understanding of whether solar is right for you.

Solar Technology Explained

The modern silicon solar cell was invented in 1954. Although there are older non-silicon cells that date as far back as 1883, the silicon cell was the first that could power an electrical device for several hours.

One of the earliest known uses of a solar cell were solar powered watches and calculators. In 1973, the first solar powered building, did not use solar panels but rather used solar roof tiles similar in design to Tesla roofs.

Types Of Solar Panels

Solar panels work by converting sunlight into electricity in a process known as the photovoltaic effect. Light from the sun carries packets of energy contained in cells called photons. These photons charge the electrons in a solar cell creating the electric current that powers the appliances in a home.

Solar panels come in different sizes. The solar panels used to power a home or large building consist of between 60 to 72 solar cells wired together, each producing between 0.5 to 0.6 volts. Typically, we use the larger solar panels for commercial buildings.

There are three main types of solar panels that dominate the consumer market today. These are monocrystalline, polycrystalline and thin-film.

Monocrystalline (Mono-Si)

Monocrystalline solar cells are made from a single crystal of silicon. This gives them their dark black color. Monocrystalline is the most efficient and also most expensive solar panel. Efficiency in a solar panel is a measure of how much solar energy a cell converts to electricity.

The average efficiency of monocrystalline is between 18 to 22 percent.

Polycrystalline (Poly-Si)

Polycrystalline solar cells are also made from silicon. They are different from monocrystalline solar cells in that they are made from multiple pieces of silicon rather than one. This is why polycrystalline solar cells have a speckled blue color. Polycrystalline is slightly less efficient than monocrystalline, but is cheaper.

The average efficiency of polycrystalline is between 18 and 20 percent. Together, polycrystalline and monocrystalline make up 90 percent of the solar panel market.

Thin-film

Thin-film is a broad category of solar cells made from a variety of materials including silicon, cadmium (CdTe) or copper (CIGS). The biggest drawback to thin-film solar cells is they have the lowest efficiency which makes them unsuited for most Northern climates. On the other hand, thin-film solar panels are typically half the price of either monocrystalline or polycrystalline.

The average efficiency of thin-film is between 9 and 13 percent.

Solar System Design

There are two main designs used for solar systems. These are grid-tied and off-grid.

Grid-tied

A grid-tied solar system is one that is connected to a major electricity grid. In this case your system is connected to the power utility. The biggest advantage to this type of system is that it allows you to sell electricity back to your utility provider as a feed-in-tariff.

The disadvantage to this system is it does not work if there is a blackout. As soon as the grid goes down, it shuts down. This is to prevent it from feeding electricity back into the grid which can be a hazard if there are any repairs being carried out on the grid.

Off-grid

An off-grid system as you may have already guessed, is one that is not connected to the grid. In this setup your solar panels and any additional power source you have provide all your electricity needs. The biggest upside to an off-grid system is you do not have to worry about a blackout as this is a self-contained system.

The downside to the system is it is more expensive since it has to be sized large enough to provide all your electricity. In a grid-tied system you can switch between the grid and your solar panels.

Installation Of Solar Panels

Solar panels can be installed on a roof or on the ground.

Roof-mounted

The biggest advantage to roof mounted solar panels is they take up less space on your property. It is also typically cheaper and more secure.

Ground-mounted

Ground-mounted solar panels are easier to maintain. They do however, take up more space on your property so they are not ideal for most installations. They also require more labor and material (mounting platforms) which makes a ground-mount more expensive.

Components of A Solar System

Depending on how it is designed, a solar system requires solar panels, inverters, batteries and charge controllers. Solar panels produce the electricity for you to use. But what are the other components for?

Inverters

Solar panels produce direct current (DC). Direct current is a more efficient way to move electricity from where it is generated to where it is used because it has less voltage loss.

The appliances in your home use alternating current (AC), however. Inverters convert the direct current solar panels produce into alternating current appliances use. There are several types of inverter systems but the most common are grid-tied, off-grid and hybrid.

Grid-tied inverters are used for grid-tied systems. They have an anti-islanding feature that shuts down your system when the grid goes down in a blackout.

Off-grid inverters are used for off-grid systems. They do not connect to the grid so they do not have an anti-islanding feature.

Hybrid inverters are used in both grid-tied and off-grid systems. They can be run even in the event of a blackout. They also allow you to sell electricity back to the grid so they combine the best features of both grid-tied and off-grid inverters.

Batteries

Batteries store the energy produced by a solar panel. They are the single most expensive component of a solar energy system. Fortunately, you do not always need batteries. They only become necessary in an off-grid system or if you want to use your solar energy after dark. There are three main types of batteries used in solar systems.

Lithium batteries are made from the same raw materials your laptop or mobile phone battery has. Lithium batteries are also used to power most of the electric vehicles on the market today. The biggest advantage to lithium for solar is that they hold more usable energy. Their biggest downside is they are the most expensive.

Sealed lead acid (SLA) batteries are the next best alternative to lithium. While they will not give you as much energy as the same size lithium battery, they do have the advantage of being much cheaper.

Flooded lead acid (FLA) batteries are possibly the oldest battery technology. The batteries that run conventional fossil fuel powered cars are lead acid batteries. The difference is solar lead acid batteries have a bigger capacity.

FLA batteries are cheaper than either SLA or lithium. The biggest disadvantage to FLA batteries is they require maintenance where lithium and SLA do not require any.

Charge controllers

Charge controllers regulate the voltage and current produced by a solar panel before sending the electricity to a battery. They protect the battery from overcharging or getting drained by solar panels. Charge controllers are only necessary in a system with batteries.

We have looked at how solar works and what the design and components of a solar energy system are. But what are the reasons for getting solar panels and what are the arguments against?

Why Should You Install Solar?

The main benefits to owning a solar energy system are as follows.

Energy Savings

Depending on the size of your system, solar can help you realize savings of between 20 to a 100 percent on your electricity bill.

For example, a system that provides all your electricity completely offsets your bill. That means you produce and consume all your electricity at no cost to you. One way to make absolutely sure you realize maximum savings from your system is to get efficient solar panels. Take our short quiz and get free solar panel quotes.

Clean Energy

Energy consumption is the second biggest producer of carbon emissions. The energy from your utility is produced from burning fossil fuels which produce greenhouse gases that are harmful to the environment.

Making your home more energy efficient and switching to a renewable energy source like solar helps you reduce your carbon footprint. This has a massive impact on reducing global warming. Solar panels can offset up to 138 metric tons of carbon emissions per year.

Home Value

Solar panels increase the value of your home. According to research, installing solar panels increases the value of a home by up to 4 percent. This can become a bonus if you decide to sell your property. On average, energy efficient homes sell faster than homes less efficient.

Payback Period

Payback period is how long the system takes to pay for itself in terms of savings. Depending on the specifics of a solar panel system (size of the system and the type of solar panels used) you will see a return on your investment at between seven to ten years.

Energy efficient homes and solar systems with a higher power output shorten the payback period. One way to improve your system output is through efficient solar panels. Take our short quiz and get quotes for efficient solar panels.

Easy Set Up

Compared to other renewable energy solutions, solar has the easiest setup. Installation of solar panels is more practical especially in an urban setup. Also, solar has a higher energy yield than most renewable energy deployments at a residential level.

Wind is perhaps the closest alternative, but unless you are in a rural environment, this is not a viable solution for most.

The Main Reasons Not To Install Solar

Solar energy is not without its flaws however. These are the two biggest disadvantages you need to consider.

Unreliable

Solar energy is not as reliable as grid supplied electricity because it depends on the sun shining. In colder climates, solar has a slightly reduced output. While you will still see savings from solar, they will not be the same as those of someone in a warmer climate.

This in turn increases your payback period. There is a significantly longer wait to see your return-on-investment the colder your climate is.

High Upfront Cost

The biggest disadvantage to solar for most people is still the cost. While the cost of solar panels has fallen by 83 percent in the past decade it is still considerably expensive. Fortunately, there are solar panel subsidies, loans and tax breaks you can take advantage of that can reduce the cost by anywhere from 30 to 100 percent.

Renewable energy incentives are finite and time sensitive, however. They get reduced as more people switch to renewables so if you want to capitalize on them you have to move as soon as you can. Take our short quiz to find get free quotes from solar panel installers near you.

Solar FAQs

Do Solar Panels Work At Night?

Solar panels produce convert sunlight into electricity. This happens only during the day. Energy storage in the form of batteries allows for extended use of solar panels at night.

Do Solar Panels Work In Cloudy Conditions?

Solar panels can produce energy even in overcast conditions. While the output is reduced to as little as 10 percent in rain, they will still generate electricity.

What Is The Lifespan Of A Solar Panel?

Most manufacturers guarantee their solar panels for 25 years. In practice, solar panels last longer. They do however, experience a minimal decline and produce less energy as they age. At the 25 year mark, a solar panel produces up to 80 percent of its rated capacity.

A good renewable energy policy is good news for consumers. If you are looking into solar or other types of renewable technologies for your home, there has never been a better time than now. Presently there are several subsidies set up to fund the purchase and operation of renewables.

What are they and who can apply for them? That is what we want to take a close look today. In this guide we will walk you through the main subsidies that can help you reduce the cost of purchasing solar panels and also profit from solar energy production.

Why You Should Apply For A Grant

The main reasoning behind providing aid is to encourage the deployment of renewables. Offering subsidies to consumers reduces the cost of renewables like solar and makes them more accessible.

This in turn speeds up the process of transitioning to a cleaner economy powered by carbon neutral energy sources. Consumer renewable energy subsidies generally take one of two forms.

1. They are aimed at reducing the upfront cost through loans, tax rebates or zero taxes on renewables.
2. They provide some form of benefit for the use of renewables through a feed-in-tariff or buyback scheme.

The upside of either of these is that consumers get renewables at a discounted cost which in turn helps the country reach its sustainable development goals. It’s a win for both consumers and the environment. There are more than 5 types of aid covering photovoltaic, thermal, hybrid and aerovoltaic systems.

The Self-Consumption Premium

This subsidy is meant to encourage solar owners to use the energy generated by their solar panel system. Through this subsidy, you are paid a bonus per year for the electricity produced from your solar panels and used by you.

The self-consumption premium is capped at photovoltaic systems below 100kWp and for the first five years of operation. The total amount is spread over five years and each year you receive 20 percent of the total.

The total is worked out by multiplying the price per kWp (at the time your system was commissioned) by the size of your system.

How Do You Qualify?

To be eligible for the self-consumption premium the main requirements are:

1. Your solar panels must be installed by an RGE certified installer.
2. Rooftop solar panels must be installed parallel to your roof.
3. The system has to have a production peak of less than 100kWp.

The rates for the bonus are determined by the number of connections there are to the grid. The more connections there are, the lower the rate so it is best to get in early if you want to lock in a higher rate. Take our solar energy quiz and find out how much solar panels are near you.

The Sale Of Surplus Bonus

If your solar panels produce more energy than you use, the excess is sold to your grid electricity supplier. This is paid out to you as tax-free income in the form of a feed-in-tariff. The rate is as follows:

The Purchase Obligation

Under this subsidy, you sign a contract with a buyer (typically the EDF) to sell them your solar energy at a rate set by law. This is slightly different from the self-consumption premium where there is no contract involved and you are selling only your excess.

Here you can sell all your production. The contract runs for twenty years and starts once your photovoltaic system starts running. At the time of writing these are the prices you should expect:

Reduced VAT

Property owners with a grid-connected photovoltaic system with a capacity of less than 3kWp can get a reduced VAT rate of 10 percent of the purchase price. This is provided the installation was carried out by an RGE certified installer. For systems greater than 3kWp the VAT rate is 20 percent.

Other renewables like heat pumps and thermal solar panels entitle you to a reduced VAT rate of 5.5 percent.

MaPrimeRénov’

This is a new subsidy (launched in 2021) that replaces the Energy Transition Tax Credit (CITE). Funds are deposited directly into your bank account once the purchase and installation of your system is complete. This fund applies only to thermal and hybrid solar systems, however. It does not apply to photovoltaic systems.

How Do You Qualify?

1. The property must be at least 15 years old.
2. You must occupy the property as your primary residence for at least 8 months out of the year.
3. The installation has to be completed within two years.

This fund is aimed primarily at providing cheaper heating for low income households. Funds are dispersed depending on the income bracket you fall in. The lower the income and the more people there are in the household, the higher the funds remunerated.

Eco-PTZ

The zero-rate eco-loan is an interest free loan. It can range anywhere from €7,000 to €30,000. Like the MaPrimeRénov’ it only covers thermal and hybrid solar systems. You have to go through a bank to access it.

How Do You Qualify?

1. The home must have been built before 1 January 1990 for homes on mainland France, and 1 May 2010 for those off mainland France.
2. Installation has to be by an RGE certified installer.
3. The property must be your main residence.

Local Subsidies

There are also smaller subsidies given at regional or local government level. Here are a few:

1. In Grand Est, you can apply for a grant to cover the installation of photovoltaic and thermal systems.
2. The Burgundy-Franche-Comté region offers financial aid of up to €7,000 for low income households for thermal systems.
3. In Bouches-du-Rhône, individuals with an annual income below €30,000, and two person households with an income below €55,000 can apply for aid of up to €6,000 for renewable energy improvements on their home.

These are some of the most important renewable financial aid programs you can take advantage of. If you are ready to take the next step to going green, take our quiz and get free quotes on solar panels.

The phenomenal growth of renewable energy in Germany has been policy driven. In line with the goal of becoming 80 percent clean energy dependent, Germany has possibly the most favorable raft of renewable energy policies in the world. It should come as no surprise that they consistently make the top five countries in terms of new solar installations.

But what solar panel grants are there and how can consumers take advantage of them? In this guide, we look at the different solar subsidies available for homeowners.

How Do Solar Panel Grants Work?

Generally, solar panel grants bring down the costs of solar panels. There are two main ways in which this commonly happens. The first is through a rebate or tax credit that reduces the upfront costs of solar panels and installation.

The second way is through buyback schemes where a utility or power company pays a consumer for the excess energy generated from their photovoltaic system. There are several types of schemes, but these are the ones you will most likely find.

Solar subsidies make it cheaper to go solar. Instead of paying the full cost, a subsidy can offset a percentage of the sticker price of a solar panel system. Subsidies also reduce the payback time or the time it takes for you to recoup your investment in a renewable energy system.

A subsidy can also significantly increase the long term savings you get when you switch to solar energy. One way to get added value from solar is to get an efficient solar system. To find out how much you can save on solar, take our free quiz and get three free quotes on solar panel systems.

Germany Renewable Energy Sources Act (EEG)

The EEG as it is also called, is the main law on renewable energy in Germany. Several amendments and changes have been made to it since it was adopted, with the most recent changes coming into force in July 2022.

The newest changes to the law affect the solar industry more than any other. In terms of the law, Germany hopes to install 215GW of solar by 2030. Some grants and incentives like low-interest loans for solar fall under this law while some are given by agencies, federal and local government.

The grants may cover the purchase of a solar panel system or batteries. This could come in the form of a one off lump sum or reimbursement for a loan or financing. The grant can also come as payment for the electricity generated by a photovoltaic system.

Solar Investment Grants

These are grants that cover the cost of purchasing a photovoltaic system or energy storage. Germany has somewhat reduced the scope of this type of grant. Rather than fund complete solar systems, the focus is now on energy storage (batteries), solar plus storage and electric car charging ports.

These grants are applied at federal state level. It is important to note that these grants are subject to availability based on the budget allocated. These are some of the largest solar funding grants in Germany.

Batteries are the most expensive component of a renewable energy system. Amendments to the EEG are meant to encourage self-consumption of energy generated by renewable energy systems. Subsidizing the high cost of energy storage is one of the ways it hopes to encourage this. There are several federal state level subsidies open to consumers with energy storage systems.

Bavaria

Homeowners in Bavaria can claim €500 for a 3kWh solar storage unit and €100 for every additional kWh under the Energy Storage Photovoltaic Program. The maximum size of the system is capped at 30kWh which means you can claim up to €3,200.

Berlin

In terms of Berlin’s Energy Storage Plus program, homeowners can claim €300 for every kWh of energy storage up to €15,000. At the time of writing, funds had already been exhausted but there is another round of funding planned for the near future.

Lower Saxony

In Lower Saxony, homeowners can offset 40 percent of the cost of energy storage or a vehicle charging port. The grant can be applied to a maximum of €50,000.

Tax Subsidies

Aside from grants, tax subsidies can also reduce the upfront cost of a photovoltaic system. This is in the form of a tax write off for the purchase of a system.

Federal Funding for Efficient Buildings (BEG)

These are a raft of grants aimed at improving energy efficiency and the use of renewable energy technologies especially in new buildings. Launched in 2021, the program has run under the “Energy-Efficient Construction and Refurbishment” name.

The program encompasses improvements on:

1. Residential buildings
2. Non-residential buildings
3. Individual measures which are improvements on a single unit rather than an entire building.

Any property owner including non-German citizens can apply for the grant. In terms of the grant, property owners are entitled to between 20 to 40 percent funding for a renewable energy system. The grant also covers the purchase of an energy efficient home. Prospective property owners can receive a loan of up to €150,000 with a 25 percent repayment grant.

Feed-in-Tariff

Grants are not only for the purchase of a photovoltaic system. They can also pay out for electricity produced by one. Your electricity supplier pays you for the electricity you feed into the grid.

The tariff at which you will be paid is locked in at the month in which your system is commissioned for 20 years. If your system is commissioned at a tariff of 6.32 cents, that is the tariff you will receive for the next 20 years.

Renewable energy grants are a great way to get the most out of your solar panel system. But policies change and it is better to take advantage of them while they are in place. Take our free quiz to find out how much solar panels cost.

In line with this, the UK has set up certain measures with the view of trying to meet their sustainable development goals (SDGs). A key part of these measures is of course, transitioning from a fossil fuel based economy to a renewable energy economy.

One of the ways the UK is trying to achieve this is by creating incentives that will encourage its citizens to adopt renewable energy solutions like solar panels and heat pumps. Incentives like these reduce the upfront cost to go solar by as much as 50 percent. In this guide, we take a look at some of the grants available for consumers looking to go solar.

What Are Solar Panel Grants?

Solar panel grants are schemes, incentives or rebates offered by the government, municipality, power utility company or an independent agency. This can be in the form of a tax credit or interest free loan that reduces the upfront cost of solar panels. It could also be credits given to a solar panel owner who exports excess electricity to the grid.

Renewable energy grants cover several other technologies besides solar panels like heat pumps for example. There are several solar schemes active in the UK that outright ease the cost or provide a benefit when you go solar.

Energy Company Obligation Scheme (ECO4)

Launched in April 2022, the ECO4 scheme replaces the previous ECO3. Under the new ECO4 scheme, the UK government has allocated a £4 billion budget for solar panel and heat pump installations. The new scheme is valid from April 1^st 2022 to 2026.

In terms of this scheme, a homeowner can be granted partial or fully funded solar panel installation. That means you can get solar panels at little to no cost if you are eligible.

How Do You Qualify?

While the scheme came into affect in July 2022, it applies to installations made from April 1^st 2022. Those eligible are:

• Homeowners and tenants.
• People on government benefits (income-related benefits, child support, housing benefit).
• Homes with a heating efficiency rating of between D to G.
• All electric homes.

Find out if you are eligible for the scheme here.

ECO4 LA Flex

The Local Authority Flexible Eligibility or LA Flex is part of the ECO4 scheme. It’s an improvement made on the original ECO3 which was flawed in terms of how eligibility for the scheme was decided.

The new LA Flex allows councils and local authorities a wider leeway for determining the eligibility of a household. The new measures target the most at risk people during cold weather who cannot afford heat (households spending up to 10 percent of their income on heat).

Each local authority determines eligibility using rules they decide so rules will vary. Find out if you are eligible here.

Smart Export Guarantee

The Smart Export Guarantee pays homeowners for any excess solar energy they export to the grid. Effective since 1 January 2020, it obligates electricity suppliers with more than 150,000 customers to pay any customers who feeds electricity into the grid from a solar system.

The SEG allows you to choose any SEG licensee. They do not have to be your electricity supplier. You can look for one that gives you the most attractive rate per kWh as well as choose the length of your contract.

It’s also important to get efficient solar panels if you want to get the most out of the SEG scheme. The more efficient your solar panels are, the more energy they produce. Take our short quiz and get quotes on the most efficient solar panels.

How Do You Qualify?

To be eligible, your home must of course be producing energy (less than 5MW) from solar panels. The home must also be fitted with a smart meter that can measure the flow of exported electricity.

The Green Deal

The Green Deal is more of a loan than a grant. It allows homeowners in England, Scotland and Wales to apply for loans covering over 40 energy-saving improvements including:

• Insulation
• Glazing
• Heating and hot water
• Micro-generation technologies like solar panels

How Do You Qualify?

Eligibility is determined by a Green Deal specialist who makes recommendations upon assessment of your home.

Zero Tax On Solar Panels

Like the Green Deal, this is not a grant as such. Previously the VAT on renewables was already quite low at 5 percent. In September 2022, the UK government froze VAT on installations of energy-saving equipment in UK homes. This freeze is time-limited and will be in place until March 2027.

This gives you four years to take advantage of zero VAT solar panels which could save you up to £800. With all these measures now is a good time to think about investing in solar panels. Take our free quiz and find out how much you stand to save if you go solar today.

How To Qualify

Zero VAT is automatically applied to the equipment itself (solar panels, heat pumps, insulation, boilers etc) and the installation.

Combined or just individually, solar panel grants can save you money on the upfront cost as well as reduce the time taken for the system to pay for itself. Over the course of their lifespan, using solar panels under the SEG scheme will deliver bigger long term savings.

Feed-in-Tariff (Defunct)

The Feed-in-Tariff ran from 2010 until 2019. While it is closed for new applications, those that applied before the cut-off can still benefit from it. This scheme is the precursor and in some ways, better version of the new Smart Export Guarantee.

Under this scheme homeowners would be paid for the electricity their renewable energy systems generated as well as the surplus electricity exported to the grid.

Conclusion

The savings from exporting to electricity to the grid can reach anywhere between £21,250 to £40,325+ depending on how favorable the tariffs are and the size of the system. This is why it’s important for you to know and take advantage of these schemes while they are still in place.

The schemes may change or become less beneficial in time. It’s a smart idea to get in as early as you can.

Light from the sun is energy dense. Solar cells absorb and convert this light energy into electricity that can power appliances like your laptop or mobile charger. But did you know you could also use solar for heating as well?

Solar heating is using solar energy to provide heat. It can also be used to cool as well. In this guide, we explore how.

Solar Heating Can Be Passive or Active

Passive heating relies on structural or architectural design to capture as much natural heat from the sun as possible. The simplest way to do this is by designing a building with large windows and skylights then facing the building in the direction where it will capture the most sunlight.

Another simple way to capture passive heat is through the materials we use. Certain materials absorb heat more readily where others are more heat-resistant. A common way of taking advantage of passive heating is painting a hot water tank black. The dark color makes it absorb more heat.

Active heating is the use of a mechanical device to collect and distribute solar energy as heat. This could be to provide space or water heating. The main difference between active and passive solar heating is the latter distributes heat naturally while active heating requires devices like pumps or collectors.

There are a number of active heating devices. Today, however, we want to focus on those commonly used for residential, commercial and industrial applications. These are solar water heating and solar space heating systems.

Solar Hot Water Systems

Solar hot water systems collect thermal energy from the sun which they then use to heat water. They are different from photovoltaicsystems that collect light energy which is converted to produce electricity.

Early solar water heating systems were passive systems. They were simple systems consisting of a tank painted black to better absorb thermal energy. Today solar water heater are a little more complex. A modern solar hot water typically consists of a collector, storage tank and a working fluid.

The working fluid in a solar water heater can be water, antifreeze (propylene glycol) or any heat-absorbing liquid that can act as a heat exchanger. There are two main types of water heaters:

1. Evacuated Tube Collectors have a series of parallel glass tubes that absorb energy from the sun and transfer the heat to the working fluid. These are the most popular type of water heater.
2. Flat Plate Collectors have a flat dark colored plate that absorbs heat and transfers it to a working fluid that circulates in tubes above the plate.

Combining solar hot water heating and solar panels can reduce your electricity bill by up to 40 percent. Take our short quiz and get free solar panel quotes.

Solar Space Heating

Solar space heating circulates heated air through a building. The air can be heated directly or indirectly. Direct heating systems use solar collector panels that absorb thermal energy and heat air. The heated air is then circulated using an HVAC outlet. Direct air space heaters heat to about 37 degrees Celsius on a sunny day.

Indirect systems are more common in colder climates where temperatures can reach freezing. Similar to solar water heaters, space heating systems use a liquid heat exchanger. Thermal energy is collected and heats the liquid exchanger.

The exchanger then circulates through a storage tank heating the water in the tank to temperatures of up to 79 degree Celsius. The hot water or heating liquid will then circulate heat through a building in one of three ways. This could be through a radiant floor, low temperature baseboard or a central hot air system.

Radiant Floor Systems

This system circulates a heated liquid through pipes embedded in the flooring. The heated liquid then radiates heat into the room. The main advantage of the system is that it is simple to implement. The biggest disadvantage to this system is that it takes longer to heat a space from a cold start than other systems.

Low Temperature Baseboards

These systems require a heated liquid of between 48 and 60 degrees Celsius. Low temperature baseboards are installed at the baseboard or at a level close to the ground to allow for heat to rise and distribute through a space more naturally.

Central Forced Hot Air Systems

In a central forced hot air system a heating coil acts as a liquid-to-air heat exchanger. The liquid heat exchanger heats up air as it is pulled through the ducts in a room.

Pros and Cons Of Solar Heating

We’ve looked at the different types of solar heating. But are they worth it and how do they compare against traditional heating and cooling methods like furnaces and HVAC systems?

Pros

1. Water and space heating contribute as much as 40 percent of a domestic electricity bill. On average they take up the biggest piece of most households electricity bill. Switching to solar can provide up to 80 percent of buildings hot water needs and offset your electricity bill. Combined with solar panels, solar heating can completely eliminate your electricity costs. Take our quiz to find out how much you can save by going solar.
2. Energy production is the second biggest contributor to carbon emissions. Solar can drastically reduce the reliance on gas and fossil fuel fueled electricity. Solar is a cleaner alternative energy source that can help you reduce your carbon footprint.

Cons

1. Solar is dependent on the sun shining. In that respect solar energy can be unreliable if it is cloudy.
2. Solar for heating typically produces less heat. It is not as efficient in terms of how much heat it can produce compared to other systems. Very often, you may have to pair your solar heating system with an alternative supplement or backup system like a furnace or heat pump.
3. Solar systems have a high upfront cost. In certain cases, the cost is not justified if the system relies too heavily on a backup system like a furnace.
