What is Solar Panel?

Overview

Solar panels are made up of many smaller units called solar cells, which are typically made from silicon. When sunlight hits these cells, it creates an electric current through a process called the photovoltaic effect. This electricity can then be used to power homes, businesses, or even fed back into the electrical grid. The way solar panels work is quite straightforward. When sunlight strikes the solar cells, it excites electrons, causing them to move and generate electricity. This electricity can be used immediately or stored in batteries for later use, making solar panels a flexible energy solution. Solar panels are important for several reasons. They provide a clean and renewable source of energy, helping to reduce greenhouse gas emissions and combat climate change. For example, many homes in sunny areas use solar panels to lower their electricity bills while contributing to a more sustainable energy future.
