How much will solar panels produce in New York?

A 8 kWp system facing south at 35° tilt in New York produces about 11,597 kWh a year. In a weak year that is 9,691 kWh, in a good one 13,503 kWh — 1,450 kWh per kWp.

That’s about 110% of a typical home’s yearly use (10,500 kWh).

Common questions

How much do solar panels produce in winter in New York?

From November to February the system produces about 3,046 kWh, which is 26% of the year. The weakest month (December) gives roughly 645 kWh.

Is an east-west roof worth it in New York?

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 New York?

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.
