Знання про ринок PV — прямо від дистриб’ютора.

Lightweight PV modules (today around 7–7.2 kg/m²) can open up commercial roofs with little spare load capacity. But lower mass alone does not solve the design — you still have to calculate the structure, ballast, wind, snow and roof condition.

Sizing a battery starts with three numbers: usable capacity in kWh, power in kW, and battery voltage. Here is how to read them and match them to the inverter so the system actually performs under load.

A hybrid inverter handles PV and storage in one device; an AC-coupled battery adds storage to an existing installation. Here is when each approach is more cost-effective and practical.
