【9BB CELLS FOR BETTER PERFORMANCE】- HQST 400 watt solar panel adopts the industry-leading 9 busbars technology, which reduces the risk of microcracks. Compared with 5BB cells solar panel, it has a better longer lifespan. 9BB 400w solar panel can also reduce the working temperature by around 2℃/ 35.6℉ to improve the module’s performance.
【22-23% CONVERSION EFFIENCY】- HQST 400 watt monocrystalline solar panels increase the light-receiving area and offer 22-23% conversion efficiency, which is higher than most conventional solar cells. Our 12V 400w solar panel provides up to 500Wh of electricity per day in 5 hours of direct sunlight.
【BETTER LOW LIGHT PERFORMANCE】- Bypass diode minimizes power drop caused by shadows, eliminates hot spots, and ensures excellent performance in low light environments. It keeps solar panels working even if some solar cells are accidentally damaged. The mono panel is constructed from high-purity silicon Class A cells, coated with advanced encapsulation materials and multi-layer sheet lamination to enhance cell performance and provide long-lasting durability.
【BUILT TO THE LAST】- Anti-reflective, high transparency, low iron tempered glass with enhanced stiffness and impact resistance. IP65 rated junction box and MC4 connectors give you the freedom to worry about water splashes and rain. Corrosion-resistant aluminum frame provides extended outdoor use, ensuring panels will last for decades. Heavy snow loads of 5400 Pa and strong winds of 2400 Pa provide excellent durability in harsh environments.
【EASY INSTALLATION】- HQST 400w solar panels come with pre-drilled holes for quick and secure installation. Compatible with HQST Z mounts and tilt mount brackets. Great for RVs, boats, and other outdoor equipment. HQST offers a 5-year warranty on materials and workmanships and a 25- year 80% efficiency power output.
