The author has been generating his own electricity from wind and sun for several decades. In editions one and two he shared his knowledge and experiences so that readers could do the same. Developments in technology and improved equipment availability in the last few years have meant that a third edition was thought appropriate, with new chapters, drawings, schematics, and photographs. The hands-on approach is retained in this edition, with lots of practical tips, and advice on using second-hand components where feasible. He provides practical advice on all aspects of building and maintaining a low-cost, low-carbon home-generation system. This book accompanies an online course. and here’s a review.
