A typical 3-bedroom house in the UK uses around 3,100 kWh of electricity per year. A 3.5 to 4 kWp system with 8 to 10 panels would generate enough electricity to cover most of this. The exact number depends on your roof size, orientation, and how much electricity you use.
A typical 4 kWp solar panel system costs around 4,400 to 5,500 pounds installed in 2026. This includes panels, inverter, mounting hardware, scaffolding, and MCS certification. Prices have fallen significantly over the past decade and continue to offer strong returns.
Yes, solar panels still generate electricity on cloudy days, though at reduced output. Modern panels can produce 10 to 25 percent of their peak output in overcast conditions. The UK averages around 900 to 1,100 kWh per kWp per year, accounting for all weather conditions.
Under the Smart Export Guarantee, energy suppliers pay around 7p per kWh for exported solar electricity in 2026. For a 4 kWp system exporting around half its output, this works out to roughly 100 to 150 pounds per year in export income, on top of savings on your electricity bill.
Research suggests solar panels can add 1 to 3 percent to a property value. They improve the EPC rating and reduce running costs, both increasingly important to buyers. However, the financial benefit depends on the age of the system and remaining warranty.
