Welcome to my website, these pages give details of the solar systems we have installed in Stonehouse, Gloucestershire and records of the outputs we have got from them. The solar hot water system was installed in September 1999 and the PV in March 2004 Our house faces 40 degrees west of south, but the PV has still managed to produce around what was predicted for a south facing roof. PV typically produces 75% of its annual output over the 6 months through summer when the sun is higher in the sky, and the remaining 25% over the other 6 months. Good Energy pay us 9.4p per kWhr for all our electricity plus 3.1p for 50% of total generation assumed as exported, we get this rate as our PV was installed before the Feed In Tariff was announced. If you install a PV system now you could get up to 43.3p/kWh plus 3.1p for 50% assumed export. By April 1st 2011 we had generated as much as imported so far that year Monthly details:- January 2012 has been the best Jan figure since system installed (56kWh), getting the year off to a good start Full details on Grid connect PV page or for solar hot water stats look at SHW performance page Last year we earned as much from our electricity as we owed on our electricity bill by 9th April 2011. From then on we are in credit for our electricity, despite not getting the full FIT amount. The solar hot water system produces over 70% of the hot water used in this house. It produced 100% of the hot water from early March to middle of September in 2000. Proving to us that solar power really does work in England. The solar hot water system was installed as a DIY installation, but the Renewable Heat Incentive is due to be launched this summer (2011) which will pay you for the hot water you generate if the system is installed by an MCS accredited installer - see links page for details. Our house faces approximately South West which is not the optimum direction, but even so water temperatures in the summer regularly reach over 70 deg C and in the middle of winter on a clear frosty day we have got the water heated up to over 40 deg C even though the air temp is below O deg!!! |
