How does solar pv work

Solar photovoltaic (PV) technology is a renewable energy source that converts sunlight into electricity. The process of how solar PV works can be broken down into several key steps.

1. Absorption of sunlight: Solar panels, also known as PV modules, are made up of individual solar cells that are made of semiconductor materials, such as silicon. When sunlight hits these cells, the photons in the sunlight are absorbed by the semiconductor material.

2. Generation of electricity: When the photons are absorbed, they knock electrons loose from the atoms in the semiconductor material. These free electrons create an electric current that flows through the material and generates electricity.

3. Conversion of electricity: The electricity generated by the solar cells is in the form of direct current (DC) electricity. This electricity needs to be converted into alternating current (AC) electricity, which is the type of electricity used in homes and businesses. This is done by an inverter, which converts the DC electricity into AC electricity that can be used to power appliances and devices.

4. Distribution of electricity: The AC electricity generated by the solar panels can be used to power homes, businesses, and other buildings. Any excess electricity that is generated can be stored in batteries for later use or fed back into the grid for credit.

Overall, solar PV technology is a clean and sustainable way to generate electricity. It can help reduce greenhouse gas emissions, lower energy costs, and decrease reliance on fossil fuels. By harnessing the power of the sun, we can create a more sustainable energy future for generations to come.
