Common questions
How much do solar panels produce in winter in Львів?
From November to February the system produces about 863 kWh, which is 13% of the year. The weakest month (December) gives roughly 136 kWh.
Is an east-west roof worth it in Львів?
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 Львів?
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.
