It does if you are happy to pay a premium for the environment. We installed a solar hot water system (coupled with a wet back on our log burner) 5 years ago. Works fine, and no need to supplement with electricity on sunny days. Obviously in winter the wetback does its job ... the most problematic times are overcasted but warm days in summer / autumn (nothing but electricity to heat the water ...).Originally Posted by westerly
However if I look at the cost of the system - and the annual payback in reduced power bills - than you look at a roughly 15 years payback period (without considering any interest ...). Investing the money in power generator shares and using the dividends to pay the electricity bill makes more financial sense, but hey ... this way we can feel like Greenies
