How much will solar panels produce in León?
A 5 kWp system facing south at 35° tilt in León produces about 7,733 kWh a year. In a weak year that is 6,468 kWh, in a good one 8,997 kWh — 1,547 kWh per kWp.
That’s about 234% of a typical home’s yearly use (3,300 kWh).

Common questions
How much do solar panels produce in winter in León?
From November to February the system produces about 1,725 kWh, which is 22% of the year. The weakest month (December) gives roughly 351 kWh.
Is an east-west roof worth it in León?
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 León?
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.
