Solar Output Per Month UK

How much electricity do solar panels generate per month?

Monthly electricity generation from a 4kW solar panel system in southern England: JANUARY: 90-120 kWh. FEBRUARY: 130-170 kWh. MARCH: 240-300 kWh. APRIL: 350-420 kWh. MAY: 450-530 kWh. JUNE: 480-580 kWh. JULY: 470-560 kWh. AUGUST: 400-480 kWh. SEPTEMBER: 300-360 kWh. OCTOBER: 190-240 kWh. NOVEMBER: 100-140 kWh. DECEMBER: 70-100 kWh. ANNUAL TOTAL: 3,500-4,200 kWh. Average UK household uses 2,900 kWh/yr — so a 4kW system generates 120-145% of total annual consumption. In summer: you generate far more than you use. In winter: you generate less and rely more on the grid. A battery evens this out.
