Different Types of Solar Panel
Raisysolar offers a full range of solar panels in stock that you can choose by type or solar panel wattage, or let us know your required specifications to benefit from our customization service.
Foldable Solar Panel
Our foldable solar panels employ ETFE durable filming technology to ensure long-term performance and Mono-Si battery cells to offer a high efficiency of 22%. Their solar panel wattage ranges from 28W to 200W, catering for both home and commercial use.
Flexible Solar Panel
Our portable folding solar panel of 28W to 200W uses Mono-Si solar panel to offer conversion efficiency as high as 22%, compared with the market average of 20%, it will generate more kilowatt-hours of power in the usable area and has better performance.
Mono Solar Panel
Monocrystalline solar panels are crafted from highly pure single-crystal silicon, ensuring exceptional quality and efficiency. Monocrystalline solar panels use pure single-crystal silicon, melted and crystallized into uniform wafers.
In-house Manufacturing of Solar Panels
Though BLJ Solar manufactures and offers three different types of solar panels, the core and important manufacturing processes of all solar panels are similar as follows:
Solar Cell Selection
Every piece of solar cell has been carefully inspected and then will be precisely cut by an automatic laser cutting machine to pick out high-quality solar cells for assembly.
Solar Cells Welding
These precisely cut solar cells will be welded by advanced automated machines to maintain product consistency, improve efficiency, and ensure the high quality of our solar panels.
Semi-product Assembley
After the solar cells are serially welded by an automated machine, we utilize a jig for precise positioning, and assembly. And electrical testing of semi-finished products is conducted.
Lamination
After solar cells are assembled and tested, we will laminate the multi-layers structure including the front panel, EVA, solar cells, and back sheet together to form a complete solar panel.
Trimming
There will be some extra dead parts after the solar panel is laminated, so we need to trim around and remove it.
Optional Service
When the final solar panel is built, we also offer some optional services as clients required, such as wire welding before go ahead performance test.
Strict Quality Control of Solar Panels
Ensuring superior quality solar panels for your energy solutions is our constant pursuit. With rigorous quality control from raw material sourcing to final delivery, we guarantee 100% inspection of each panel. Our well-equipped laboratory conducts industry-standard and customized tests to meet your specifications. Our quality management includes:
Raw Material Inspection
All incoming raw materials will be carefully inspected, including electrical performance inspection and classification of high-quality solar cells, cross-linking test of high-quality EVA, and durability test of backsheet, etc.
In-house Manufacturing Quality Control
Complete performance test will be conducted throughout the whole manufacturing processes, including EL testing, electrical performance testing of semi-finished solar panels, electrical performance testing of finished solar panels, etc.
Finished Solar Panel Tests
All solar panels are subject to final product testing to verify compliance with industry standards as well as customer specific requirements.
