Introduction to Solar Panels
Solar panels, also known as photovoltaic panels, are devices that convert sunlight into electricity. They are a key component of solar power systems, which are an important source of renewable energy. Solar panels are made up of photovoltaic cells, which are usually made of silicon. When sunlight hits these cells, it causes electrons to be excited and flow, generating an electric current.
Solar energy is clean, abundant, and sustainable. Using solar panels to generate electricity helps reduce reliance on fossil fuels, mitigates environmental pollution, and contributes to the global effort to combat climate change.
