620W Longi Solar Panel (HiMO 7 LR772HGD620M)

The 620W LONGi Solar Panel (HiMO 7 LR772HGD620M) is a high performance bifacial photovoltaic module designed for utility scale, commercial, and large residential solar installations. Built using LONGi’s advanced HPDC cell technology and dual glass construction, this panel delivers exceptional energy yield, long term reliability, and industry leading efficiency. With a maximum module efficiency of up to 23.0%, the 620W LONGi solar panel is engineered to maximize power output per square meter, making it ideal for projects where space, performance, and lifetime value are critical. High Power Output and Energy Yield This module offers a rated power output of 620 watts under standard test conditions, with a 0–3% positive power tolerance to ensure guaranteed performance. Its bifacial design provides additional rear side power generation, enabling higher total energy production when installed on reflective surfaces. The low temperature coefficient and half cell design reduce power loss in high temperature environments and improve overall system stability. Advanced Bifacial Dual Glass Design The dual glass structure enhances durability and resistance to moisture, salt mist, sand, and harsh environmental conditions. With a bifaciality factor of 80% ±5%, the panel is capable of capturing reflected light from the rear side for increased system yield. This makes the 620W LONGi Hi?MO 7 panel well suited for ground?mounted, tracker, and large rooftop installations. Long Term Reliability and Warranties LONGi’s lifecycle quality assurance ensures dependable performance over decades. The module includes: 12 year warranty for materials and workmanship 30 year linear power output warranty with less than 1% first year degradation and only 0.4% annual degradation from year 2 to 30 This guarantees stable energy production and strong return on investment over the system’s lifespan.
