Solar Power (photovoltaics) is now a one-billion-dollar industry, and it’s poised to grow rapidly in the near future as more pressure is placed on limited fossil fuel resources and as advances in solar technology drive down the costs of residential solar systems. This book helps readers understand the basics of solar power and other renewable energy sources, explore whether solar power makes sense for them, what their options are, and what’s involved with installing various on and off-grid systems.
