From April 1, households which install photovoltaic solar panels and feed the energy (green electricity) in to the national grid will be paid 41.3p per kilowatt hour (kWh).
A typical 2.5 kWh system takes up about 10 feet by 10 feet and costs about £14,000 (with install). The Department of Energy and Climate Change (natch) estimates this size of kit will produce about 2,125 kWh per year - so total returns (including reduced electricity bills) would be in the region of £1,050 per year. You can also factor in a property price boost.

Remember, under NuLab governments you peons are only fit for means-tested credits in order that you can be controlled. For the rest of us, wahey! That's a yield of 8 per cent. Maybe this climate change bollocks isn't so bad after all.
