Longi Solar 620W bifacial panel from the Hi-MO 7 series (model LR7-72HGD-620M) is a beast that’s all about squeezing more power from the sun without needing a ton of space. This bifacial panel grabs light from both sides—front for direct rays and back for reflected light off the ground or roof—so you could see up to 20-30% extra yield in the right conditions, like on white gravel or snowy areas. Built with top-tier monocrystalline cells and dual-glass for extra toughness, it’s resistant to harsh weather, PID issues, and even hail, making it a go-to for folks in variable climates like Kenya’s mix of sun and rain. At 620 watts, it’s efficient (around 23%), cuts down on installation costs since you need fewer panels, and pairs great with modern inverters for grid-tie or off-grid vibes. Longi Solar 620W bifacial panel got a rep for reliability, and with a 30-year power warranty, this one’s designed to keep pumping out clean energy for decades, helping you slash those electricity bills while doing your bit for the planet.
Longi Solar 620W bifacial panel Key Features
- Bifacial Technology: Captures sunlight from both sides for boosted energy production—ideal for reflective surfaces, potentially adding 20-30% more output compared to standard mono panels.
- High-Efficiency Monocrystalline Cells: Up to 23% module efficiency with advanced HPBC tech, performing well in low-light and high-heat scenarios without much power drop.
- Dual-Glass Construction: 2mm tempered glass on front and back for superior durability, fire resistance (IEC Class C), and resistance to environmental degradation like salt mist or ammonia.
- Robust Build for Harsh Conditions: Handles extreme temps from -40°C to 85°C, high wind/snow loads (5400Pa front, 2400Pa rear), and hail up to 25mm—perfect for tough installs.
- IP68 Junction Box: Waterproof and dustproof with 3 bypass diodes to minimize shading losses and hot spots, ensuring consistent performance.
- Long-Term Warranties: 12-year product warranty against defects and a 30-year linear power warranty down to 87.4% output, backed by Longi’s global reputation.
