Positioning

A solar PV module will produce electricity from a number of different angles and directions, however a solar system performs at its optimum when facing due south and between 30-45% tilt.

This is assuming throughout the day there are no objects causing shade to fall on the solar PV array.

It's very important there is as little shade as possible, preferably none. A solar PV array is usually made up of 6 panels or more. The PV system is wired together in series which means even if just one panel is partially shaded, the power output of the whole system will drop.

Feed-in solar PV can be installed on a range of roof types including Pitched and Flat. Solar PV can even be installed on the ground.

Area Required

The smallest Feed-in solar photovoltaic system is approximately 8mē. Please remember this does not mean you need to have a roof space that is 2m x 4m, the panels can be installed in a variety of arrangements.

A feed-in design quotation includes technical drawings; these drawings show the exact positioning and size of the proposed PV system.

Planning Permission

As a general rule planning permission is rarely required for a solar PV system, however it is important to notify your local planning service as a letter of non conformity is usually required for grant applications.

There are only two exemptions to this general rule:

• If your property is a listed building
• If you live in a conservation area, national park or any other designated area
