solar efficiency

Solar efficiency refers to how well a solar panel converts sunlight into usable electrical energy. It is expressed as a percentage: the higher the efficiency, the more sunlight the panel can transform into electricity. For example, a panel with 20% efficiency turns 20% of the sunlight hitting it into electrical power, while the rest is lost as heat or reflected away. Factors affecting efficiency include the materials used, panel design, and environmental conditions. Higher efficiency panels produce more electricity in the same amount of space, making them advantageous for maximizing energy generation.
