We all want to save the world, but I think Solar is one initiative that should be handled by large scale installations supported by State and Federal Government subsidies. Apart from being a crappy ROI for home owners, there is the added hassle of the potential problems the home installation could cause to the roof of the dwelling over a period of time. Hopefully that will be limited to a some minor roof leaks, uneven fading of colorbond , moss on the tiles or the like. But what about in a severe storm. Will we see solar panels in flight? Sounds like a lot of hassle for nothing to me. I will just elect to quietly purchase a percentage of green power from the utility and pass up the opportunity to show off my solar panels as a demonstration of my commitment to reducing greenhouse gas.
