Hello, this is my first post but have been reading for a while. We are just completing on our plot purchase in Scotland and are looking to use solar pv instead of a normal roof on a passive house. I find it really sad that people base there decisions purely on economics. If economics area all we base our decisions on then there will no planet left and the point where we won't be able to stop that being the case is pretty much now. The decisions you are making now about how to heat and power your home have a direct impact on whether or not we will have a planet to live on. The Government can't do it alone.
