Solar Photovoltaic Panels for Public Sector
Public sector buildings including schools, leisure centre, council buildings and hospitals are excellent candidates for installing renewable energy systems. As most of their energy consumption is during the day and that’s when solar system generates electricity, they can dramatically reduce their energy bills and cut their CO₂ emissions. And best of all, as they are generating electricity at the same location as they are consuming it, there are no transmission losses or costs.
Solar Photovoltaic panels has been around for many decades so the technology is well and truly established. Solar is also the only ‘fit and forget’ technology as it requires virtually no maintenance or service. Most Solar panels come with a 25 year performance guarantee, meaning they will generate at least 80% of their rated power for 25 years. In the last two years the take up of Solar has increased exponentially and consequently the cost of Solar panels has come down drastically. In October 2011 the cost of a Solar installation of up to 20kW was around £ per Watt. A year later it is around £1.50 per Watt. On this basis a Solar installation on a house can provide annual returns of between 10-14% and a payback of 6-7 years if you include the savings and Government Tariffs.
- Cut your electricity bills: sunlight is free, so once you've paid for the initial installation your electricity costs will be reduced.
- Get paid for the electricity you generate: the government’s Feed-In Tariffs pay you for the electricity you generate, even if you use it.
- Sell electricity back to the grid: if your system is producing more electricity than you need, or when you can't use it, you can sell the surplus back to the grid.
- Cut your carbon footprint: solar electricity is green, renewable energy and doesn't release any harmful carbon dioxide] or other pollutants. A typical home solar PV system could save over a tonne of carbon dioxide per year – that's more than 30 tonnes over its lifetime.
