Common questions
What Kyiv and Sumy customers ask
01How much does 1 kW of panels generate in Kyiv and Sumy?
Per PVGIS, about 944 and 935 kWh per year respectively at optimal tilt. The monthly distribution is in the table above: winter output is 7–10 times lower than summer, and our forecast shows this rather than hiding it behind an annual average.
02Does a solar plant work during a grid outage?
A grid-tied inverter without storage shuts down with the grid — a safety requirement. A hybrid system with a battery keeps feeding the backup circuits, which is why we design hybrid architectures for homes.
03Will the roof take the panel load?
Before design we verify structural capacity, roofing material and wind and snow loads. For older roofs we propose reinforcement or an alternative array location.
