Solar power systems, which are designed to capture solar energy, include everything from small home systems to large commercial and utility scale installations. These systems can either be grid tied, sending surplus power to the grid and drawing power when needed, or off-grid where energy storage is utilized. Solar panels, inverters, batteries, and charge controllers are key components. Technological advancement has greatly improved the efficiency, reliability, and cost of solar power systems, which in turn accelerates the shift to renewable energy worldwide.
