design and installation of solar power
Solar Photovoltaics (PV) |

Solar Electricity Solar PV (PhotoVoltaic) uses energy from the sun to create electricity to run appliances and lighting. PV requires only daylight, not direct sunlight to generate electricity and so can still generate some power on a cloudy day. The Benefits: PV systems produce no greenhouse gases. A typical domestic system can save approximately 1.2 tonnes of carbon dioxide per year. adding up to almost 30 tonnes over a systems lifetime. In addition a 2kWp system could provide enough electricity to meet around half a households electricity needs each year. PV cells are referred to in terms of the amount of energy they generate under peak conditions, known as kilowatt peak or kWp. Types of System: The most economical PV system is the grid connected system. Most importantly, from April 2010 a new feed-in tariff (FIT) becomes available for solar PV. PV installations will receive 41.3p per kilowatt-hour (kWh) generated, with a further 3p per kWh for excess electricity sold back to the grid (prices guaranteed for 25 years). This effectively reduces the payback period for the installation and can increasingly be used to generate income. The other type of system is known as off grid and uses batteries to store the electricity.

PV Panels: Bright Energy are proud to be able to supply and fit PV panels from SCHOTT, Schüco and Mitsubishi. These panels are some of the best on the market and are of superior design and manufacture. The panels supplied produce between 160Wp and 180Wp. Costs: Prices for PV systems vary depending on the size of the system to be installed. The size of the system is dictated by the available roof space and budget. For the average domestic system costs will be around £5000 per kWp installed with most domestic systems usually between 1.5 and 3 kWp.
