l know it's been quite a while since carbon legacy installed my panels, but l did say l was skeptical about the clams you made and the figures you gave me. But as you seamed more knowledgeable and less pushy than the other company's l had received quotes from. l had them installed by you, and l said I would give them long enough for a fair trial before getting back in touch with you again which l have now done. the result is that l have a very red skeptical face. Because your clams and figures were on the low side by quite a lot so obviously l am very pleased with my purchases. but the best thing about the system is the part you just mentioned in passing and l asked for more information on, and decided in for a penny in for a pound as they say. That was that l would have batteries and hot water heating as well and boy am l glad l did. and if anyone is not sure what l am on about the panels supply the needs of the House first then before any electric is sent to the national grid the panels send Electric to a large hot water cylinder and heat the water for free, and l also have batteries that are charged up free from the panels so l have free Electric at night as well. this is a God send when you are out at work all day. and as the amount of power you send to the national grid is estimated I get the same allowance as everyone else so l am winning again. So Thanks David it's no often l can say l am glad l was wrong. p. s. l take credit for asking for more information on the hot water and the batteries p.p.s. my combined Electric and gas bills were £48.90p for the last three months that's for the three months not each month. Not forgetting that the money I receive from the Government and the national grid is a lot more than my bills at the moment So thanks again David.
