I have been asked a few times recently, is it still worth getting Solar installed at home on your roof. I have gathered the data and completed the calculations, The answer still seems to be yes.
Despite the current governments lack-lustre support of micro renewable generation and the almost complete decimation of the micro wind generation market, a micro solar installation still looks like it will pay the initial outlay back within a reasonable time.
The following link will take you to a simple calculator for returns from solar installations based on average prices recorded as part of the official MCS certification process.
Based on our estimates, a 4kW installation (the average size) would cost about £7264 and pay for itself in about 10 years. The total value of savings over 25 years is an estimated £35,385 and over 26 tons of CO2.
