How much will solar panels produce in Miami?

A 8 kWp system facing south at 35° tilt in Miami produces about 13,112 kWh a year. In a weak year that is 11,006 kWh, in a good one 15,219 kWh — 1,639 kWh per kWp.

That’s about 125% of a typical home’s yearly use (10,500 kWh).

Common questions

How much do solar panels produce in winter in Miami?

From November to February the system produces about 4,246 kWh, which is 32% of the year. The weakest month (June) gives roughly 968 kWh.

Is an east-west roof worth it in Miami?

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 Miami?

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.
