Dont waste your money its an antique
Ive had this book 4 years it was out of date then. I recently bought The Renewable Energy Handbook by kemp which is far more up todate. 8 years in Solar Electrics is a lifetime, the equipment shown and discussed is fit for a museum,sure its solar electricy for the indepedant home, as a model t ford is for cruising the motorway,save your money!
