How much will solar panels produce in Nottingham?

A 4 kWp system facing south at 35° tilt in Nottingham produces about 4,000 kWh a year. In a weak year that is 3,342 kWh, in a good one 4,658 kWh — 1,000 kWh per kWp.

That’s about 148% of a typical home’s yearly use (2,700 kWh).

Common questions

How much do solar panels produce in winter in Nottingham?

From November to February the system produces about 622 kWh, which is 16% of the year. The weakest month (December) gives roughly 119 kWh.

Is an east-west roof worth it in Nottingham?

An east-west system typically produces 10–25% less per kWp than one facing south, but spreads production more evenly through the day. The exact difference depends on tilt and shading.

Ground mount or roof in Nottingham?

A ground mount can be tilted and aimed freely, which can add some yield, but it costs more and needs space. Compare both for your own plot.
