Solar Electricity – Solar PV (Photovoltaic)

PV (Photovoltaic) Solar Panels are normally positioned on a southerly facing roof to ensure they gain the maximum amount of light and sun. Solar Panels can be heavy so checks should first be made to ensure the roof is strong enough to support them. Additional strengthening works may be required if not. Alternatively, if you have an open area then the panels could be positioned on a frame in the garden providing there are no obstructions preventing direct access to the sun. Tree’s, hedges or buildings close by may detract from the efficiency of your solar panels, which will generate electricity during daylight hours, even if the sun is not shining. Whilst planning permission is not normally required when installing solar panels, you should check with your local department as conditions differ in many areas.

A typical domestic 4kw system will consist of twelve solar panels. Each panel is approximately 5 x 3 feet and they are usually installed in two rows of six. Although this can differ if the roof or garden requires it.
