How Much Does One Panel Produce?
Independently written

How much electricity does one solar panel make?
One 400W solar panel produces approximately 380-420 kWh per year in the UK (south-facing). Per day: 1.0-1.2 kWh average. Summer peak: 2.0-2.5 kWh/day. Winter low: 0.2-0.4 kWh/day. That single panel saves approximately £93-£103 per year at 24.5p/kWh — enough to pay for itself in under 3 years. 10 panels = 4kW system = ~4,000 kWh/year = matching average UK household consumption.
