""" my only regret is I had not read this sooner. i had a tiny home solar system installed in 2020 by a ""professional"" and it cost thousands and never worked correctly. It is currently broken and I have to rebuild (And respend) the money to make it right. I take superb comfort that by reading this book I can now correct the grave inconsistencies and working with my new installer, make sure it is done RIGHT. I only wish I had read this book before forking over all that money, knowledge truly is power. My thanks to the authors for the amazing book, well laid out and worth the price all day! """
