In recent years, there has been a significant increase in the number of homeowners in the United Kingdom who have installed solar panels on their roofs. This is due in part to the rising cost of electricity and the desire to reduce carbon emissions. But just how much does it cost to install solar panels at home in the UK?
The cost of solar panel installation varies depending on a number of factors, including the size of the system, the type of panels used, and the location of the home. According to the Energy Saving Trust, the average cost of a typical 4kWp solar panel system in the UK is around £6,200. However, this figure can vary significantly depending on a number of factors.
Size of the system
The size of the solar panel system will have a significant impact on the cost of installation. The larger the system, the more expensive it will be to install. A typical 4kWp system will cost around £6,200, but larger systems, such as a 6kWp or 8kWp, can cost upwards of £10,000 or more.
Type of panels
The type of solar panels used will also affect the cost of installation. There are two main types of solar panels – monocrystalline and polycrystalline. Monocrystalline panels are more expensive than polycrystalline panels, but they are more efficient and take up less space on the roof. The cost difference between the two types of panels is generally around 10%.
Location of the home
The location of the home will also affect the cost of installation. Homes located in areas with more sunlight will require fewer solar panels than homes located in areas with less sunlight. Additionally, homes located in areas with higher electricity rates will see a greater return on investment from solar panel installation.
Government incentives
The UK government offers a number of incentives to encourage the installation of solar panels. The most significant of these is the Feed-in Tariff (FIT) scheme, which pays homeowners for the electricity they generate from their solar panels. The FIT scheme pays a fixed rate for every kilowatt-hour (kWh) of electricity generated, regardless of whether it is used in the home or exported to the grid. The rate paid depends on the size of the system and the date of installation, but is generally around 4-5p per kWh.
The FIT scheme was closed to new applicants in 2019, but homeowners who installed solar panels before this date will continue to receive payments until the end of their contract.
Other incentives include reduced VAT rates on solar panel installation, and the Renewable Heat Incentive (RHI), which pays homeowners for the heat generated by their solar panels.
Return on investment
Despite the upfront cost of solar panel installation, homeowners can expect to see a significant return on investment over the lifetime of the system. The Energy Saving Trust estimates that a typical 4kWp solar panel system can save homeowners around £250 per year on their electricity bills, and generate around £8,000 in income over the 20-year lifespan of the system.
Conclusion
In conclusion, the cost of installing solar panels in the UK varies depending on a number of factors, including the size of the system, the type of panels used, and the location of the home. The average cost of a typical 4kWp system is around £6,200, but the actual cost can be higher or lower depending on these factors. Despite the upfront cost, homeowners can expect to see a significant return on investment over the lifetime of the system, thanks to government incentives and the ability to generate their own electricity.
