Solar potential in Cluj-Napoca: how much can photovoltaic panels produce?
Monthly PVGIS production, specific yield, local comparison and a financial calculator for a photovoltaic system in Cluj-Napoca.
Estimated photovoltaic production in Cluj-Napoca
For the standard reference configuration of 5 kWp, PVGIS estimates approximately 6,262 kWh/an, adică aproximativ 1,252 kWh/kWp/an and an average of 17.2 kWh/zi.
This is an energy estimate and depends on coordinates, orientation, tilt, losses and the real installation conditions.

PVGIS estimates energy production using solar-radiation data and system parameters. The result is an energy estimate, not a production guarantee. Local shading, module temperature, soiling, inverter limits, system downtime and the actual installation configuration can change real production.
