How Much Do Solar Panels Generate?

How much electricity do UK solar panels produce?

A typical UK solar system generates approximately 950-1,050 kWh per kWp installed per year. A 4kW system: 3,800-4,200 kWh/year. A 6kW system: 5,700-6,300 kWh/year. This varies by: location (southern England: +10%, Scotland: -10%), roof direction (south: 100%, east/west: 80-85%), and season (summer: 60-70%, winter: 10-15% of annual total). All estimates already account for UK weather including clouds and rain.
