What Are Solar Panels Made Out Of?
Solar panels are primarily made from silicon, which is excellent at absorbing sunlight and converting it into electricity. The silicon cells are protected by a tempered glass layer that shields them from weather and captures more sunlight. To keep this glass clean and maximize sunlight absorption, solar panel cleaning is important. A metal frame, usually aluminum, holds the panel together, and wiring connects the cells to an inverter, converting direct current (DC) to alternating current (AC) for home use
Some panels, like thin-film solar cells, use materials like cadmium telluride or copper indium gallium selenide. These materials make the panels lighter and more flexible, ideal for unique installations like curved surfaces or windows. Some panels also have extra coatings, like those on PERC panels, which improve efficiency by reflecting more sunlight back into the cells.
Each part of a solar panel is designed to enhance energy production, ensure durability, and suit different needs, helping you choose the best option for your home. If you’re unsure which option is right for you, don’t hesitate to contact us for personalized recommendations.
