Modern panels reach 18–23% efficiency. That means they convert about one-fifth of sunlight into usable power. But efficiency is only part of the story. Real-world performance changes with temperature, shading, tilt angle, and even the quality of the inverter or battery. . The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 24%.
