Solar Cell Efficiency

Solar cell efficiency refers to the percentage of sunlight that a solar panel can convert into usable electricity. For instance, if a solar panel has a 20% efficiency rating, it means that 20% of the sunlight hitting the panel is transformed into electrical energy, while the rest is reflected or absorbed as heat. Higher efficiency means more electricity generated from the same amount of sunlight, which is crucial for maximizing energy production, reducing costs, and making solar energy a more viable option for homes and businesses. Factors influencing efficiency include material quality, design, and technology used.
