Solar PV

Since their first commercial deployment in space in 1964 one of the most successful technologies in the 21st century is Solar Photovoltaic panels generating low CO2 electricity from free sunshine. We are often asked if Solar panels work when its cloudy, the short answer is yes, read the long answer in our blog post here.Millions of houses in the UK have retrofitted solar PV on their roofs and reduced their electricity costs significantly. Sadly the Government backed Feed-in Tariff has now been ceased, but a reasonable return can still be made from solar PV, particularly if significant roof works are part of your project.A typical domestic installation comprises 10-24 solar PV panels, an inverter (handling the connection between the panels and the home electrical system and grid) and generation meter. Normally the panels are fixed on the roof, the inverter is in the garage or your loft and the meter close to your fuse board.The PV panel life expectancy is 25+ years normally supplied with a manufacturer’s warranty, which assures an 80% performance after 20 years. Inverters typically have a 5 or 10 year warranty.
