HOW DO SOLAR PANELS WORK?

Solar panels function by capturing sunlight and converting it into usable electricity through the photovoltaic effect. At the core of this process are solar cells made from semiconductor materials, typically silicon. When sunlight strikes these cells, it excites electrons within the semiconductor, generating an electric current. This process effectively transforms solar energy into direct current (DC) electricity.

Once generated, the DC electricity is routed from the solar panels to an inverter, which converts it into alternating current (AC) electricity for consumer use. This transition is crucial because most household appliances and systems operate on AC electricity. The inverter also regulates the flow of electricity to ensure optimal performance and prevents damage to the devices using the energy.

Furthermore, solar power systems can be equipped with batteries that store excess energy produced during peak sunlight hours.
