A solar panel is a device designed to convert sunlight into electricity using photovoltaic (PV) technology. It captures solar energy through specially designed cells that generate direct current (DC) power when exposed to sunlight. Solar panels are commonly used in residential, commercial, and outdoor applications to provide clean, renewable energy for lighting, appliances, and electrical systems. Durable and energy-efficient, they help reduce electricity costs and environmental impact while offering a reliable power source in both grid-connected and off-grid setups.
