Solar Panel Daily kWh Output

How many kWh do solar panels produce per day?

A 4kW UK solar system produces an average of 10-11 kWh per day across the year. This varies hugely: clear June day: 22-25 kWh. Cloudy June day: 10-15 kWh. Clear March day: 12-16 kWh. Overcast December day: 1-3 kWh. The average is exactly that — an average. Summer produces 4-6x more per day than winter. Your monitoring app shows daily output in real-time.
