Solar PV

Photovoltaic (PV) solar panels turn light in to electricity. They rely on light rather than heat so although they work best in direct sunlight, they will still produce power even on a dull day. Barres can supply and install both domestic and commercial PV systems.

The ideal situation for Solar PV is an unshaded, south facing roof in good condition with plenty of space. Panels can also be mounted on a east/west facing roof and on the ground using a variety of methods. A normal electricity connection to the grid is also required.

For domestic properties, the normal size of a PV system is up to 4kW. Above this size, grid planning permission is required which adds extra cost and is not as cost effective unless going significantly beyond 4kW. The roof space available also becomes an issue when going above 4kW.
