Solar Panels Costs in the United Kingdom 2024
The total cost of solar panels depends on a number of factors, including the size, type, and number of panels, as well as the location and cost of labor for installation. Find out the average solar installation prices in the UK
The cost of solar panels in the UK has come down significantly over the past decade, thanks to advances in technology and increased competition in the market. In 2023, the average cost of a solar panel will be between £150 and £300. The most common solar installation is a 3.5 kilowatt-peak (kWp) system, which would typically require around 10 solar panels (350W each) and cost between £5,000 and £10,000.
1. Here are some factors that can affect the cost of solar panels in the UK
- System size: The larger the system, the more expensive it will be.
- The type of panels: There are two main types of solar panels: monocrystalline and polycrystalline. Monocrystalline panels are more efficient but also more expensive.
- The quality of the panels: The quality of the panels will also affect the price.
- Installation location: Installation costs will be higher in areas with more difficult roof conditions.
- Labor Costs: Labor costs vary depending on location and installer.
The government has also introduced a number of financial incentives to make solar panels more affordable, including:
Feed-in Tariff (FiT): FiT is a government program that pays you for the electricity produced by your solar panels. FiT is currently being phased out but is still available for some systems.
Smart Export Guarantee (SEG): SEG is a government program that pays you for the excess electricity your solar panels generate and export to the grid. The SEG replaces the FiT.
The Renewable Heat Incentive (RHI): The RHI is a government program that pays you for the heat generated by your solar panels. RHI is available for solar thermal panels, which use solar energy to heat water.
Overall, the cost of solar panels in the UK remains relatively high but has come down significantly in recent years. With financial incentives from the government, solar panels can be a cost-effective way to generate your own electricity and reduce your carbon emissions.
2. Cost of Solar Panels per kW System in the UK
A standard 250W solar panel in 2023 costs between £400 and £500, but can vary depending on the type and size of the entire system. One of the most common domestic sizes is a 4kW solar panel system, which costs around £6,400 and will cover around 29 square meters of your roof.
And for 350W solar panels in 2023 cost between £700 and £800. One of the most common domestic sizes is a 4kW solar panel system, which costs around £9,500 and will cover around 22 square meters of your roof and cut your electricity bill by 64%.
