1. System Functioning:
System Priority: Solar>Grid
The installations operates automatically. When the solar radiation is detected by photovoltaic array, the systems turn on power production and starts running. On the other hand, if photovoltaic array is not detecting solar radiation, the system turns off.
The Production increases until midday (maximum radiation) and
decreases at sunset.
Cloudy day: The system detects low radiation and Production starts according to the radiation
So,in a cloudy day, the system can operate in lower performance but still is able to produce power required.
