1- A charge controller and inverter convert the direct current of panels to enter the electrical network and then to electrical appliances. This is done by transforming panel tension into a 230v stable current. In the same way, it transforms total tension of panels to a stable current of 230V which is higher.
2- Solar Photons, which are like light grains, penetrate the photovoltaic cell and remove electrons from the silicon atoms. Once removed, these electrons are organized by an internal electrical field and their movement produces an electrical current.
3- A power consumption meter is used to count the the smallest watt produced by the power station.
