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 21p/kWh plus 3.1p for 50% assumed export. By March 19th 2012 we have generated as much as imported this year, over a week sooner than last year. 2012 Monthly details:- January - has been the best Jan figure since system installed (56kWh), getting the year off to a good start February - has been well above average and easily the second best Feb figure since system installed (82kWh, 6 year average 71), continuing the good start to the year March - has continued the record breaking run this with the best March figure since system installed (174kWh) and also had the best March week at 58kWh -previous best 47kWh April - has continued the record breaking run but this time as the worst April since system installed (148kWh, average 190kWh) this has also been the wettest April since Met office records began in 1910 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 autumn 2012 for domestic properties which will pay you for the hot water you generate if the system is installed by an MCS accredited installer . 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!!! |
