First Solar is a company that makes something called "solar panels". These panels are special because they can take the energy from the sun and turn it into electricity that can power things like your TV or computer.
The panels are made up of lots of little cells called photovoltaic cells. These cells are made of special materials that react to sunlight and create electricity. When the sunlight hits the cells, they create a flow of electricity that is then sent through wires and used to power things.
First Solar is really good at making these solar panels. They make them in big factories where they carefully put together all the pieces that make up the panels. Once they make them, they can sell them to people who want to use them to make their own electricity using the power of the sun.
Using solar power is good for the environment because it doesn't create pollution like burning coal or gas does. So, using First Solar's solar panels can help make our planet cleaner and healthier for everyone.
