Common questions

How much do solar panels produce in winter in Fortaleza?

From May to August the system produces about 3,341 kWh, which is 41% of the year. The weakest month (February) gives roughly 497 kWh.

Is an east-west roof worth it in Fortaleza?

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 Fortaleza?

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.
