Alex, there is definitely "a demand" or at least a wish list. Have been looking for a way to build a solar system to run the well house water pump, the furnace and maybe a couple of plugs. Over 10 years all the contractors contacted want 10 to 15 thousand $ or more for a system which would have no battery back up and would shut down when the power goes off. Not very useful. I have the basic skills to build and plumb a building as have done much of that for myself. I am not the only senior with limited income who wants to pursue solar. We (I) need a list of materials and sources if not Home Depot, Lowe;s etc and basic blueprints for a simple system which could be a starter and added to at a later date as finances allow. Your idea of a web site addressing these problems would be a boon to many. If and when you get your idea up and running, post it on FB and other social media and you could trigger a landslide of people who need you and your knowledge. For those of us who are just starting on the solar path, a single source would be helpful.
