How much will solar panels produce in Hastings?
A 5 kWp system facing north at 35° tilt in Hastings produces about 7,655 kWh a year. In a weak year that is 6,361 kWh, in a good one 8,948 kWh — 1,531 kWh per kWp.
That’s about 109% of a typical home’s yearly use (7,000 kWh).

Common questions
How much do solar panels produce in winter in Hastings?
From May to August the system produces about 1,966 kWh, which is 26% of the year. The weakest month (June) gives roughly 403 kWh.
Is an east-west roof worth it in Hastings?
An east-west system typically produces 10–25% less per kWp than one facing north, but spreads production more evenly through the day. The exact difference depends on tilt and shading.
Ground mount or roof in Hastings?
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.
