The primary type of energy produced by solar panels is solar photovoltaic (PV) energy. Solar panels convert sunlight into electricity through the photovoltaic effect, where semiconductor materials generate direct current (DC) electricity upon exposure to light. This electric energy can be used directly to power homes and businesses or converted to alternating current (AC) for broader electricity grid usage. Solar energy is renewable, sustainable, and environmentally friendly, helping to reduce greenhouse gas emissions and reliance on fossil fuels. As technology advances, solar panels are becoming more efficient and cost-effective, making solar energy an increasingly viable alternative for powering the world.
