Common questions

How much do solar panels produce in winter in Florianópolis?

From May to August the system produces about 2,051 kWh, which is 30% of the year. The weakest month (June) gives roughly 440 kWh.

Is an east-west roof worth it in Florianópolis?

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 Florianópolis?

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.
