By the numbers

Cornwall solar, measured.

Typical yearly generation, per kW of panels

≈1,055 kWh per kWp a year — roughly 10% above the UK average

For every kilowatt of panels, a well-placed Cornwall roof generates about this much a year. Your own total depends on roof direction, pitch and shading — the roof check estimates it for your address.

Quietest · December ~35 kWh
Apr–Sep share ~69%

Sunlight peaks in summer and dips in winter, so a system is sized for the whole year, not just the peak. Estimated from PVGIS climate data for your postcode area; a roof survey confirms your exact figure.
