1. Silicon Extraction and Purification: solar panel companies start with the extraction of silicon, typically from quartz sand. Silicon is abundant but must be purified for solar panel companies. This involves a process called carbothermic reduction, where the sand is heated with carbon at high temperatures to extract silicon.
2. Ingot and Wafer Creation: The pure silicon is melted and formed into large cylindrical ingots. These ingots are then sliced into thin wafers. This slicing must be precise to ensure the wafers are the correct thickness for optimal solar panel companies efficiency.
3. Cell Manufacturing: The wafers are then processed into solar panel companies. This involves doping the silicon with other elements like phosphorus and boron to create an electric field. An anti-reflective coating is also applied to the surface of the cells to increase light absorption and efficiency.
4. Panel Assembly: Individual solar cells are then assembled into solar panel companies. The cells are interconnected in a series and encased in protective materials like glass and a durable backing. This assembly ensures the panel can withstand environmental factors like weather.
5. Testing and Quality Assurance: Once the panels are assembled, they undergo rigorous testing. This testing ensures that the panels meet industry standards for efficiency, durability, and safety.
6. Distribution and Installation: The finished panels are then distributed to suppliers and installers. These panels are installed on rooftops, in solar farms, or in other locations, depending on the application and the customer’s needs.
7. Power Generation and Use: Once installed, the solar panel companies convert sunlight into electricity through the photovoltaic effect. This electricity is either used directly, stored, or fed into the power grid.

Throughout this process, companies like Qcells, Silfab Solar, JA Solar, Jinko Solar, and Canadian Solar, among others, are constantly innovating to improve efficiency, reduce costs, and enhance the sustainability of their products​​. For instance, Qcells’ significant investment in the U.S. market reflects a broader industry trend of increasing domestic manufacturing​. Additionally, technological advancements like TOPCon solar cells are making panels more efficient and cost-effective​.

The entire process, from silicon extraction to electricity generation, represents a remarkable convergence of technology, engineering, and sustainable energy production, with these leading companies at the forefront of innovation and eco-friendly energy solutions.
