How Photovoltaic (PV) Cells Work

Have you wondered how solar PV cells work? PV cells are panels we attach to your roof or walls. Each cell is made from one or two layers of semiconducting material, usually silicon. When light shines on the cell, it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. PV cells come in a variety of shapes and colors, from grey “solar tiles” that look like roof tiles to panels and transparent cells that you can use on conservatories and glass.

The strength of a PV cell is measured in kilowatt peak (kWp). That’s the amount of energy the cell generates in full sunlight.

How an Inverter Works

Inverters convert DC, generated in the solar panels, into AC. Synchronized with the supply voltage, this AC is then either fed into the circuit of the home or into the utility transmission grid.

Inverters can also assume the task of monitoring the grid. This term includes all measures required for the protection of people and devices in case of a power outage. Inverters are programmed to immediately stop operating in case of irregular grid conditions and to interrupt feeding the grid.
