A Solar Photovoltaic system (or Solar PV as it is commonly known) is a renewable technology which utilises free energy from the sun to generate electricity. The electricity produced by Solar PV can be used to drive anything from an appliance to a light bulb that is usually powered by the mains electrical supply.
Solar PV relies on daylight to generate power through the use of photovoltaic cells within roof mounted panels(modules). These modules are generally fixed to a roof and connected by cables into an inverter. This converts the DC electricity produced by the modules to AC (the same as the electricity that comes from the National Grid) which is either consumed within the property or sold back to the power supplier.
These types of solar panels use grade A solar cells which are made from a very pure single large crystal, cut from ingots. These are most efficient type of solar cells. Their performance is attested to be superior to many alternatives in low light.
The Solar PV system has many unique features. It is available in simple kit form ranging from 0.50kW (three modules) upwards to 40kW making ordering straightforward. Bespoke systems of almost any size can also be designed and supplied using the same basic components found in the kits.

The systems utilise MCS Accredited 250 Watt multi-crystalline Solar PV modules. The module frames are made from corrosion-proof, anodised aluminium and meet the highest requirements in terms of stability and durability

Solar panels are calculated to produce electricity for an average of 6 hours per day. A 200W panel will produce 6 x 200W = 1.2kWh per day. 5 x200W panels will produce 6 x 1000W = 6kWh per day. In the summer the system will produce more as the day length is longer. How many panels does a house require depends on electricity usage.
It is not necessary to buy a system from the start that provides all the electricity. The system is modular and extra panels can be added at a later date. There are also great financial incentives for fitting PV which make this proposition very desirable. Go to MCS Grants and Tariffs for further information.
