Thinking about going solar? It's more than just shiny rectangles! Understanding the materials that make up solar panels is key to appreciating their technology and lifespan.
The star of the show is **silicon**, typically in crystalline form (mono- or polycrystalline). It's the semiconductor that converts sunlight into electricity. But silicon needs help!
**Glass** protects the delicate silicon from the elements, usually tempered for durability. **Aluminum** forms the frame, providing structural support and weather resistance. Encapsulation materials like **ethylene-vinyl acetate (EVA)** seal the silicon cells, preventing moisture damage.
Finally, **conductive materials** like copper connect the cells and carry the electricity. A **backsheet**, often made of polymer, provides insulation and protection on the rear of the panel.
So, next time you see a solar panel, remember the blend of materials working together to harness the sun's power!
