Solar PV

Solar photovoltaic cells (PV) convert light into electrical energy. The amount of electrical energy produced depends on the amount of light that falls on the PV material. PV requires only daylight, not direct sunlight, to generate electricity although the output from a PV cell will vary with the intensity of the light. 

PV cells come in all shapes and sizes and can be connected to the national grid or simply to a battery bank. In any event, they will significantly reduce the running costs of any building in which they are fitted..

PV cells generally come in the form of rectangular panels of variable sizes, or in the form of individual solar slates, that are installed on the roof in very much the same way as roof tiles.

Both the rectangular panels, and the solar slates, are invariably fitted in multiples and they can be fitted in any configuration. For example, they can be fitted in portrait format, landscape format, in the shape of a T (to avoid roof lights), or in a random format.

The solar tiles are always integrated into the roof but the rectangular panels can either be integrated into the roof or fitted on mounting brackets above the roof. The chosen installation method has no effect on the output of the panels.
