HOW DO SOLAR PANELS WORK?
Solar panels function through the utilization of photovoltaic (PV) cells that convert sunlight into electricity. Composed primarily of semiconductor materials like silicon, these cells generate an electric current when exposed to sunlight. The process begins when photons from sunlight strike the surface of the panel, energizing electrons in the semiconductor. This excitement frees the electrons, allowing them to flow through the material, creating a direct current (DC). An inverter subsequently transforms this DC into alternating current (AC), which is the standard electricity type used in homes and businesses. The efficiency of this energy conversion largely depends on the quality of the solar cells, the panel design, and external factors such as temperature and sunlight intensity. As technology continues to evolve, the performance of solar panels increases, enabling homeowners and businesses to harness more solar power effectively. This process not only provides clean electricity but also paves the way for a substantial reduction in greenhouse gas emissions, setting a positive course towards sustainability.
