Solar panels work by harnessing the sun’s energy through photovoltaic cells. These cells, typically made of silicon, absorb sunlight, releasing electrons that create an electric current. An inverter then converts this direct current (DC) into usable alternating current (AC) electricity. This clean, renewable energy can power homes, businesses, and more, reducing reliance on traditional fossil fuels and lowering environmental impact.

Solar panels have a lifespan of about 25 to 30 years on average. Factors influencing longevity include the quality of materials, manufacturing, and maintenance. Notably, most panels come with a performance warranty of 25 years, guaranteeing their efficiency only until this time. While degradation occurs over time (around 0.5% to 1% annually), modern panels are designed for durability, ensuring reliable energy production throughout their lifespan.
