How are Solar Panels made?
Solar panels are intricate devices that harness the power of the sun and convert it into the type of electricity we use in our houses. They have become increasingly popular due to their renewable energy generation capabilities, environmentally friendly nature, and as a way to SAVE MONEY ON POWER BILLS.
The production of solar panels typically begins with the extraction of silica, a key component in silicon, from quartzite rock. The silica is then subjected to a series of chemical reactions to produce pure polycrystalline or monocrystalline silicon, which forms the basis of the solar cells. Monocrystalline silicon is considered more efficient, but it is also more expensive to produce compared to polycrystalline silicon.
Once the silicon is obtained, it undergoes several additional steps to transform it into usable solar cells. The silicon is sliced into thin wafers using a wire saw or a diamond saw. These wafers are then polished to achieve a smooth surface and remove any imperfections. The wafers are typically rectangular or square in shape and have a bluish to black hue.
Next, the wafers go through a process called doping. This involves adding impurities to the silicon to alter its electrical properties. Phosphorus is commonly used as a doping agent to create a negatively charged layer on one side of the wafer, while boron is used to create a positively charged layer on the other side. This creates a p-n junction, a crucial component for the solar cell’s functioning.
After doping, a layer of anti-reflective coating is applied to the front surface of the solar cell. This coating helps to reduce the reflection of sunlight and increases the amount of light absorbed by the cell. Different materials such as silicon nitride or titanium dioxide can be used for this purpose.
Once the individual solar cells are ready, they are interconnected to form a larger module or panel. Conductive wires are soldered onto the front and back of each cell, creating a series of interconnected cells. These wires allow the flow of electricity generated by each cell to be combined and collected. The interconnected cells are then encapsulated within a protective layer, often made of tempered glass, to shield them from environmental factors such as moisture and physical damage.
The encapsulated solar cells are assembled into a frame, usually made of aluminum, to provide structural support. This frame also facilitates the installation and mounting of the solar panel. The backside of the panel is covered with a protective backing, such as a polymer or a sheet of Tedlar, to further enhance its durability.
Finally, the assembled solar panels undergo rigorous quality control testing to ensure their performance and reliability. These tests include checking the electrical output, inspecting for any defects or damage, and verifying the panel’s ability to withstand various environmental conditions.
In summary, the production of solar panels involves a series of complex steps, starting from the extraction of silica to the assembly of the final product. From the production of silicon wafers to the creation of solar cells, the doping process, application of anti-reflective coatings, interconnection of cells, encapsulation, and quality control testing, each step plays a crucial role in manufacturing solar panels. The result is a clean and renewable energy solution that helps reduce our reliance on fossil fuels and contributes to a more sustainable future.
The better panels come from reputable manufacturers that have stringent quality controls and checks in place. The best raw materials and processes make the best panels. We use our experience to work through the “chaff from the hay” and are very particular about the solar panels we recommend and use on our jobs.
Every step of our process from design, product selection, installation, testing and commissioning is always focused on quality, yield and performance. A solar system is a performance product. You rarely get great performance at a budget price, no matter what the product. The same is especially true of Solar. To focus only on Price for the largest electrical appliance you will ever but in your lifetime is a mistake. We are not expensive, just very careful how we spend your money when you engage us for your solar system.
