Solar power has entered the mainstream as the world’s cheapest energy source, leaving many people wondering how solar photovoltaic cells  can be so efficient and inexpensive while still providing   renewable energy. Answering that question means understanding how solar energy works , how solar panels are manufactured, and what the parts of a solar panel are. Most panels available on the market are made of monocrystalline, polycrystalline, or thin film (“amorphous”) silicon. In this article, we’ll explain the different ways solar cells are made and what parts are required to manufacture a solar panel.
