Solar That Really Works fills a previously all but unexplored need. In one tightly written book, Collyn covers all that is needed to design and install solar electrical systems in anything from a tiny caravan or campervan to a large fishing camp. It includes the specialised needs of big converted coaches and the increasingly accepted fifth-wheeler caravans. Solar That Really Works covers just what can and cannot realistically be run from a typical solar installation. It shows how to calculate the energy required, shows simple ways of finding out the most probable solar energy available anywhere and anytime in Australia and New Zealand. It shows just how much solar panels really do produce (it’s a lot less than that apparently claimed).
