How Solar Works.

PV modules are made up of specially coated silicon cells. As sunlight falls on these cells electrons move from one side of the silicon to the other and an electrical current is produced, the more cells there are the more current is generated.

The electricity generated by the PV modules is converted from DC to AC by an inverter and connected to your consumer unit. The electricity flows to wherever it is needed to power your home. At times when there is more electricity being generated than is needed it will flow out through a meter into the grid. The meter records total electricity generated by the system. When demand for electricity in the house is greater than that being generated by the panels, electricity is drawn from the grid in the normal way so you will never be without electricity.

There are no moving parts to wear out, with the system working completely silently. The leading component manufacturers that we deal with offer lengthy guarantees, typically from around 10 years, but these vary from manufacturer to manufacturer. Our in-house control processes ensure we specify and fit the appropriate system for your needs.

Photovoltaic systems do not need bright sunshine to generate electricity. However they do generate more in summer than winter due to there being more hours of brighter sunlight. The orientation of the panels is important—the closer they are to south facing, the more energy will be generated. The optimum angle of inclination is between 30 and 45 degrees.
