The cost of buying and installing solar panels for your home in the UK can vary widely depending on several factors, including the size of the system, the type of panels, the complexity of the installation, and the installer you choose.

​

Average Cost Estimates

​

Small System (1-2 kW): Suitable for a small household, this system size might cost between £1,500 and £3,000.

Medium System (2-3 kW): For an average-sized household, expect to pay between £3,000 and £6,000.

Large System (3-4 kW): This size is suitable for larger households, with costs ranging from £6,000 to £9,000.

Very Large Systems (4+ kW): For homes with significant energy needs or those looking to maximise their generation capacity, costs can exceed £9,000.

 

Other Factors to Consider

​

Cost per Watt: The cost of solar panels is often discussed in terms of cost per watt of capacity. In the UK, the average cost might range from £1.50 to £2.00 per watt, depending on the factors mentioned above.

​

Installation Costs: The figures mentioned include the cost of the panels themselves and the installation costs. Installation costs can vary significantly based on the complexity of your roof, the need for additional scaffolding, or electrical upgrades to your home.

​

Incentives: While the Feed-in Tariff (FiT) scheme has ended, the Smart Export Guarantee (SEG) allows homeowners to earn money by selling surplus electricity back to the grid. This can offset some of the installation costs over time.

 

Energy Savings: Solar panels can significantly reduce your electricity bills. The exact savings will depend on your electricity usage, the size of your solar panel system, and how much electricity it generates. Typically, a 4 kW system could save you up to £270 per year on your electricity bill, but this will vary with individual circumstances.

 

Battery Storage: Adding battery storage allows you to store excess electricity for use when the sun isn't shining, increasing your self-consumption and saving more on your energy bills. However, this adds to the initial cost, with battery systems typically costing several thousand pounds.

 

Getting the Best Deal

​

Quotes: It's advisable to get quotes from several reputable installers to compare prices and services. Prices can vary significantly between companies.

​

Quality and Warranty: Don't just look for the cheapest option. Consider the quality of the panels and the warranty period, as these will impact the long-term value of your investment.

​

Government Schemes and Grants: Stay informed about any government schemes, grants, or incentives that could help reduce the upfront cost of solar panel installation.
