How to read your solar production data
Read kW as power right now and kWh as energy over time. Judge your system on monthly and yearly kWh per kWp, compared with a realistic benchmark from the EU's free PVGIS tool for your address and roof. Season and weather explain most low days. A sudden drop on clear days, a flat low peak or a recurring alarm points to a real fault.
