Sunshine to Dollars is a very cool book, it has a great balance of theory with how to advice. I haven’t followed any of the plans in the book my self, but I have used all the concepts to enhance existing projects, and to design new ones.
I really like the concepts in this book, particularly the idea that it is more efficient to use the heat energy of the sun directly – rather than turn the energy into power to be used to create heat later…
The author, Harris, is well known in the preparedness and sustainable living worlds. He is a frequent presenter and speaker and has written a lot of books of use toward off grid living. Solar power happens to be his best topic, but I have also enjoyed his work with ethanol fuel production, and plan to give workshops on homestead fuel production at Dual Homestead as soon as I can qualify for a license.
The only thing I have against Sunshine to Dollars is that it took things Harris did, but that may not be available to everyone, and suggest they are universal how-tos.
His example on how to get free solar panels is the most prominent. I admit his method is ingenious, but I found that after a couple years of trying, it is not quite that easy.
