Solar photovoltaic modules generate and store electricity from the sun's energy through the use of rechargeable modules.
They produce energy that contributes to the running of appliances and lighting within the home whilst emitting no greenhouse gases.
DIFFERENT TYPES OF PHOTOVOLTAIC PANELS
Photovoltaic systems convert solar radiation into electricity. The simplest systems provide electricity to a building directly but they can also be used with batteries to store energy. PV panels can be stand-alone or mounted to a suitable wall or roof.

WHERE CAN THEY BE USED?
Solar photovoltaic systems are suitable for use in almost any building. They require a south-facing area for the panel to be mounted on and can be used as a stand-alone energy supply or hooked up to the main grid.
WHAT ARE THE BENEFITS?
They do not generate greenhouse gases, saving CO2 emissions.
Grants are available to cover 50% of the installation costs- dramatically reducing the pay-back period.
There are a number of installation options available including on-roof, canopy, façade, sky light and complete roof solutions.
INSTALLING SOLAR ENERGY PANELS
Although easy to install, the location and aspect, weather, shade and tilt should all be considered first- these factors will affect the performance of the system. Planning permission may also be required.
The PV system can connect in to the local electricity network, any excess can be sold back to the grid. Contact your local electricity provider for further details.
In a stand-alone system, solar electricity is stored in a battery for use at a later time.
You can use PV systems for a building with a roof or wall that faces within 90° of South, as long as no other large buildings or trees shadow it.
In England changes to permitted development rights for domestic renewable technologies mean that most solar PV installations do not require planning permission as long as they respect certain size criteria. Exceptions will apply for installations on flat roofs, listed buildings and buildings in conservation areas.
