Frequently asked questions
What homeowners ask most often
On average 8–16 weeks in total. The actual installation takes 1–3 days; most of the time is spent obtaining the ATR and the distributor approval (4–8 weeks), a step that does not depend on us.
No, for rooftop systems under 100 kWp. ELECRO handles all the paperwork, including the prosumer file.
It is fed into the grid and metered by the bidirectional meter. You monetize it with your supplier at market price, offsetting consumption during periods without sun.
Yes. On cloudy days the system produces 15–40% of its rated power, and panel efficiency increases at low temperatures. The annual production accounts for all seasons.
Without a battery: faster return on investment (typically 5–7 years). With a battery: greater independence from the grid, payback 7–10 years. We recommend a battery especially for consumption above 400 kWh/month.
