SOLAR ELECTRICITY (PV) - ALSO KNOWN AS PV PANELS
Solar PV Introduction
Photovoltaic Solar panels use the sun's energy to produce electricity. The Direct Current (DC) electricity produced is fed to an inverter which converts it to 230Vac that can be used within the home. The output of the inverter is wired back to the consumer board to supplement the electricity you draw from your supplier and so reduce your bill. Any surplus electricity may be sold back to the grid as part of the ‘feed-in tariff’ incentive. Feed-in tariffs were confirmed for the UK on 1st April 2010 and make PV an attractive investment.
How does Solar PV work?
- Roof mounted Solar PV panels collect daylight energy and convert it to Direct Current (DC) electricity
- An inverter converts the generated DC into AC (Alternating Current) electricity similar to that supplied from the grid
- The converted AC electricity is fed into your mains supply via the consumer unit (fuse board)
- Unused energy may be sold back to the local electricity supplier when feed-in tariffs have been confirmed
How much does Solar PV cost?
- Costs depend mainly on the number of panels installed and the ease of installation
- A fully supplied and installed 3kWp system will cost from around £10,000.
What is a 1kW Solar PV peak system?
A 1kW peak (1kWp) can, in optimum conditions, deliver 1kW of energy. In reduced sunlight and cloud cover, the amount of energy delivered from the panels will be less than this.
A 1kWp system will consist of:
- Up to 6 PV panels totalling around 8m2 in area
- A safety DC isolation switch
- An inverter
- A safety AC isolation switch
- A connection to the consumer board via a safety RCBO (Residual Current Breaker with Overload protection).
A 1kWp system will typically produce up to 750kW hours per year which is around 25% usage of electricity in the average household
Is planning permission required for my Solar PV system?
- Planning permission is not usually required for roof mounted solar panels
- Planning permission may be required in conservation areas; please check with your local authority
- Solar roof panels are not generally allowed on listed buildings but other options may be available, please contact us for further information
A recent survey found people are willing to pay more for a home built to high environmental standards. Therefore with such a system your house value will increase, possibly even covering the installation costs, if not more.
