JJN Solar has revolutionized solar energy with its cutting-edge transparent backsheet design on solar panels. Unlike conventional solar panels that only generate electricity from the front, JJN's 200W bifacial solar panels can harness sunlight from both the front and the back, significantly boosting energy production. This innovative design makes them ideal for a wide range of applications, from residential rooftops to off-grid systems for RVs, boats, and more. 1, The 400W solar panel set (containing two 200W panels) is built with advanced 16BB N-type solar cells, achieving an impressive efficiency of over 25%. Compared to traditional 9BB/10BB solar cells, these panels are: a, More compact, saving space while delivering higher power output. b, Less affected by shading, ensuring consistent performance even in partially shaded conditions. 2, JJN Solar prioritizes durability and performance in challenging conditions. The 400 Watt solar panels feature: a, A black corrosion-resistant aluminum frame that combines sleek aesthetics with robust construction. b, The ability to withstand strong winds up to 2400Pa and snow loads up to 5400Pa, ensuring reliability in harsh weather. c, IP67-rated solar connectors and an IP65-rated junction box, providing exceptional waterproofing and protection against environmental particles and low-pressure water jets. 3, Designed with user convenience in mind, JJN's bifacial solar panels include: a, Pre-drilled holes on the back for quick and hassle-free installation. b, A lightweight design, with each 200W panel weighing just 24.3 lbs, making them easy to transport and mount. 4, JJN Solar stands behind the quality and durability of its bifacial solar panels with: a, A 10-year workmanship warranty, ensuring peace of mind for a decade. b, An output warranty guaranteeing over 80% performance after 30 years, highlighting the panels' long-term reliability and efficiency.
