Solar Self-Consumption: Does the PV System Consume Energy at Night? | Schneider Electric

What happens during the night? Does the photovoltaic system consume energy? At night, the photovoltaic system does not produce electricity. Even though photovoltaic inverters are on standby, they consume a little bit of electrical energy. Do they consume a lot? Usually, the night time consumption of photovoltaic inverters is lower than 1 Watt. To know the exact value, you have to check their technical specifications. Shouldn’t we avoid these losses? Standby power losses can be avoided by disconnecting the photovoltaic system during the night. Anyway, this is rarely done because disconnection requires the use of additional equipment and a daily switching operation.
