Ground-mounted PV projects are becoming more relevant in the solar industry as project sizes get larger and the nature of projects changes from an asset held by a building owner to a pure investment. Unlike rooftop systems, which are limited by the size of roofs, ground-mounted systems can be constructed on a much larger scale, offering investors financially attractive projects. In addition, the growing market penetration of low-cost thin-film PV technologies, which require a larger area than traditional crystalline silicon PV, drives growth in ground-mounted systems. More mature solar markets like Germany and Spain have a good history of large ground-mounted systems. Most industry analysts predict tremendous growth in the US for large ground-mounted systems over the next several years.
