In addition, part funding of the cost of installation is available for "green energy" projects of this nature. See below for website details for grants and advice for panel installation. Installation of a solar photovoltaic (PV) system provides a way to generate your own electricity from the free energy of the sun. A photovoltaic system will never have to be refuelled, they emit no pollution, and can operate for over 30 years with little maintenance. They can also be used in conjunction with a small wind turbine to "top up" your power requirements, and can supply electricity back to the grid when there is no power demand in the home. The term "Photovoltaic" means electricity from light. These systems use daylight to power ordinary electrical equipment, e.g. household appliances, computers and home lighting. The photovoltaic (PV) process converts solar energy into electricity, the output from the PV panels is DC, to enable the electrical supply to be used for home use it must be converted to AC at 230 V, this is achieved by fitting an inverter unit.
Note: solar thermal technology used for home heating and hot water purposes is not based on PV technology. In addition, a meter is required to ensure that home owner can get credit for any PV power fed back into the mains supply. There is a good reference source for additional information on this subject which includes typical set up, suppliers and grants available for PV systems, together with listings of electricity companies participating in the power credit scheme for homeowners who feed power back to the National Grid. See: PV-WEB British Photovoltaic Association.

Thermal Solar Panel Installations For Hot Water The Solar PV Panel system described above is used for supplying power to appliances in the home. For home hot water systems a different installation is required. The basic set-up for roof solar panels is described below. For domestic hot water applications there are three main components:
This type of hot water installation can add value to your home. Solar panels, or solar collectors must be installed on the roof. These collect the heat from the sun's radiation. The heat transfer system uses this source of heat to provide hot water. The hot water cylinder stores the hot water that is produced during the day and can supply the hot water for use later. Is my home suitable for solar panels? You will need approx. 2 to 4m2 of southeast to southwest facing roof which receives direct sunlight for most of the day. Also required is space in the home to locate an additional hot water cylinder if required. The cost for installation of Solar Panels can be expensive, and the payback time may extend to several years. Little maintenance is required for this type of installation, for more detailed information see: See also Domestic Wind Turbines for home renewable energy products.
