The author has been generating his own electricity from wind and sun for several decades. In both edition one and two of Wind and Solar Electricity he shared his knowledge and experiences so that readers could do the same. Dramatic 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, as well as 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. Wind and Solar Electricity accompanies an online course – details of which are given in the book.
