[QUOTE="binky, post: 444253, member: 490"] have a look here for info / books [URL="http://info.cat.org.uk/"]http://info.cat.org.uk/[/URL] The only DC earthed panels I've seen were the old style 'thin film' type, I don't think this is relevent to todays technology. Couple of things though, water is best heated via thermal panels. Avoiding converting from DC to AC is a lot more efficient, so would limit AC stuff to machinery that you can only buy as 240V like washing machines. Avoiding all power consuming items that you don't need like CCTV is also a good idea A wind turbine is definetly a good idea as these can work 24/ 7 if you are in a windy spot Don't use lorry batteries - wrong technology. I kind of get the impression you are trying to have a 'normal house' and making renewable energy sources fit that expectation - you may get rather disappointed. The nature of renewables is that they are rather variable in output especially during winter months, so a genie is almost certainly a necessity. Reducing loads is essential. A lot can be done with PV / wind etc etc, but there are limits. [/QUOTE]
