How Solar Panels Work

The panels on the house convert the sun’s energy into electrical


The electricity is changed through a control device to allow it to safely pass into the house


A breaker box allows the electricity to be circulated to outlets in the building


This then powers electrical items such as lights and televisions

The most popular type of cells used in solar panels are photovoltaic (PV) which are made from semi conducting material. These type of cells work through daylight, not just sunlight, so are able to produce electricity even on cloudy days, although this is at a reduced rate.

Once the sun’s rays have been captured by the cells they are passed through an inverter to change it from a direct current (DC) into an alternating current (AC) which is compatible with the items in your home.

The current can be sent into your house to help power your items, or can be sent to the national grid and used by others.

How Are Cells Split?

PV cells are split into two layers, one which carries negatively charged electrons and one which has more positively charged carriers. Due to this an electric field, commonly referred to as a junction, is created which allows the positive and negative charges to flow to the opposite sides of the cell.

The stronger the sunlight the more electricity that can be produced. When the two cell ends are connected then electricity can be conducted away as a direct current.
