solar panel efficiency

Solar panel efficiency measures how effectively a panel converts sunlight into usable electricity. It’s expressed as a percentage: for example, a 20% efficient panel turns 20% of the sunlight hitting it into electrical power. Factors like the materials used, technology, and design influence efficiency. Higher efficiency panels generate more electricity from the same amount of sunlight, making them ideal for limited space. However, more efficient panels often cost more initially. Overall, efficiency helps determine how much energy a solar system can produce, impacting cost-effectiveness and suitability for specific installations.
