Off Grid Home Forums Technical Discussion Zero-energy solar homes Re: Zero-energy solar homes


I’d like to point out here that the pay back on solar systems is still like around 50 years at current energy prices (obviously it depends, we were doing some calcs at work the other day (we’re a bunch of building services engineers so we do this all the time) and in some instances the pay back is still 70 years. Lots of energy goes into the production and transport of cells and other technologies. So lets make this one clear, zero energy homes is a non sense expression. I believe its a good idea to pay for independence and security, but give me a break, no one goes green to save money, because the economics dont work like that unless you’ve got large amounts of socialist subsidies – and that is hardly a fair, free market way to go about things is it?
