Babrock Premium 20 Watt Solar Panel with Multi Pin Mobile Charger Heavy Quality W-678 Solar Panel  (Pack of 20)

It is made with high efficiency solar cells. We source high performance Multi Crystalline solar cells and other raw material from leading international suppliers to provide and long-term reliability of PV Modules. solar panels use only 'Grade A' quality, high purity silicone cells. does not incorporate used, rejected, refused or second-hand cells into its solar panels. Furthermore, utilizes the most advanced technologies in the production of its panels, such as a fully automated, microprocessor guided, precision, robotic arms guided soldering process of the solar cells. The solar cells are coated with a blue nitride anti-reflection coating. This special coating process provides a uniform blue hue color and increases light absorption in all weather conditions. The encapsulation and lamination process used with solar cells consists of a process that ensures true atmospheric vacuum and encapsulation of cells within lamination layers of High Ethylene Vinyl Acetate (High-EVA) and DuPontTM Tedlar. Each panel is equipped with low-iron, patterned, tempered glass. The glass has been manufactured, again, through a proprietary process, providing up to 60% more strength, as compared to conventional photovoltaic (PV) glass. As a result, panels are among the world's strongest, with hail impact survival index rating of 25mm@80 km/h. This means the specialized PV glass of panels can withstand hail size of 1+ inch, traveling at speeds of approximately 50 miles per hour.
