- 【9BB TECHNOLOGY】- The 400 watt solar panel utilizes industry leading 9-bus technology, which significantly reduces the risk of micro-cracking and provides a longer lifespan than solar panels with 5BB technology. This 9BB 400W solar panel can even lower the operating temperature by about 2°C/35.6°F, thus optimizing module performance.
- 【High Efficiency Conversion】- The 400W monocrystalline solar panel expands the light receiving area to achieve a high conversion efficiency of 22-23%, surpassing most traditional solar cells. Under 5 hours of direct sunlight, our 12V 400 watt solar panel can generate up to 500Wh of electricity per day.
- 【Low light environment】- Bypass diode effectively reduces power loss due to shadows and eliminates hotspots, ensuring excellent performance in low light environments.
- 【Ruggedness】- Anti-reflective, high transparency, low iron content tempered glass is used to enhance rigidity and impact resistance.IP65 rated junction box and MC4 connectors allow you to avoid worrying about splashing water and rain. The corrosion-resistant aluminum frame provides protection for long-term outdoor use, ensuring that the panel will last for decades.
- 【 Easy Installation 】 – The 400 watt solar panel comes with pre-drilled holes for quick and safe installation. Compatible with Z mounts and tilt mounts, perfect for RVs, boats and other outdoor equipment.
