Common questions
What Kyiv and Sumy customers ask
01How much does 1 kW of panels produce for a business in Kyiv or Sumy?
Per PVGIS, about 944 and 935 kWh per year respectively. For a business the hourly profile matters more: the share of daytime consumption defines self-consumption and the project economics.
02What is zero-export and why use it?
A mode in which the plant sends no surplus to the external grid: the inverter limits generation using meter readings. It allows operation without surplus-sale arrangements; the setting is demonstrated at commissioning.
03Production is idle on weekends — what about generation?
The weekend profile lowers self-consumption and affects payback. Before design we evaluate storage, load management or generation limiting.
