In this chart’s estimates the solar panel’s output used is 350W, which is the standard for many high efficiency panels. Although these numbers provide a helpful guide, remember that they are general estimates. The exact number for your home’s energy requirements may differ. More on that later.
Most home panels can each produce between 250 and 400 Watts per hour. According to the Renewable Energy Hub, domestic solar panel systems usually range in size from around to 1 kW to 5 kW. Allowing for some cloudier days, and some lost power, a 5 kW system can generally produce around 4,500 kWh per year.
As we saw above, the average UK home uses around 3,731 kWh per year. So a 5 kW system, or possibly a 4 kW system, would probably do the trick. A 3.5 kW system usually needs about 12 panels 2, and a 4 kW system might need 14 or 15. You’ll need to measure your (south-facing!) roof to work out whether you can fit 14-15 panels up there.
A solar panel typically has 15 to 22% efficiency. For instance: High-efficiency panel: A solar panel with an efficiency of 20% converts 20 of every 100W of sunlight that strike it into usable electricity. Moderate-efficiency panel: A solar panel with an efficiency of 15% converts 15 of every 100W of sunlight it receives into usable power.
Size and number of solar panels: Given the insolation and solar panel efficiency, a 3kW system requires around 8 panels (each with an approximate capacity of 375W). This system’s potential output could be around 2,220kWh annually. Size and number of solar panels: A 6kW system requires about 16 panels (each with an approximate capacity of 375W).
Roof space plays a significant role in determining the maximum solar system size. A 4kW system usually requires around 26 square metres of roof area, approximately the size of two and a half parking spaces. , or 16 standard panels (240W-250W), taking up around 26m² of roof area – the equivalent of just under two and a half parking spaces.
