Solar PV (Photovoltaic) systems are technologies that convert sunlight directly into electricity using solar panels. They are one of the most widely used renewable energy solutions because of their efficiency and eco-friendly nature. A typical PV system consists of solar panels, inverters, batteries, and other control devices. These systems can be installed on rooftops, open land, or even integrated into building structures. Solar PV systems reduce dependence on conventional fossil fuels and help lower carbon emissions. They are highly suitable for homes, businesses, and large-scale power plants. With proper installation, they provide reliable and cost-effective electricity for many years. Advances in storage technology have made solar PV more practical by ensuring power supply even at night. Government incentives and subsidies are also encouraging their adoption. Overall, Solar PV systems are a key step toward achieving sustainable and clean energy goals.
