In part due to falling costs, increased competition, and improved consumer awareness, nationwide solar activity has tripled over the last six years, and has increased 30 percent over the last year.
Pro Remodeler, which took data from BuildFax and the Solar Energies Industries Association, notes that the cost to install solar has dropped by more than 70 percent in the last decade. Also, California constitutes 44 percent of the total market share.
The largest cost savings for solar exists in so-called soft costs such as labor, supply chain and overhead. SEIA predicts the solar industry will install 14.5 GigaWatts of capacity by the end of 2016, nearly double the amount installed last year. It also predicts more than 5,000 residential solar installations by 2020.
