Solar energy
Solar panels are a key technology for converting sunlight into electricity. They power solar farms, homes, industrial facilities, water pumps and many other applications. But how does raw silicon become a photovoltaic cell that produces electrical current? We trace the complete manufacturing process—from silicon purification and wafer production to cell fabrication, module assembly, testing and quality control—and explain the materials and technologies that influence panel efficiency and service life.

Solar energy
Solar energy is one of the most important renewable energy resources. As technology advances, it is playing a larger role in homes, businesses and industry. Sunlight can be converted into electricity, used to heat water and buildings, and help reduce dependence on fossil fuels. In this Niawell introduction, we explain what energy is, how the Sun produces it, how photovoltaic and solar-thermal technologies work, and where solar power is used. We also introduce the main parts of a solar power system, including panels, inverters, batteries and associated equipment.
