Solar power is generated by photovoltaic (PV) solar panels. These panels convert sunlight into usable direct current electricity and are currently installed in over 100 countries. However, our current PV panels do not convert energy efficiently enough to be considered a feasible energy alternative. Why? Roughly 16 percent of sunlight that hits the panels is being converted into usable energy. With more efficient models already in production, solar power may become the world’s primary energy source in the future.
