Longi Solar has released a brand-new series of photovoltaic modules and introduced “Hybrid Passive Back Contact” cell technology. The new Hi-MO 7 series will initially be available in four different formats, primarily aimed at rooftop solar power plants.
The monocrystalline bifacial solar panel LR8-66HGD-615 bifacial is used in grid-tied, hybrid, or off-grid solar power plant systems. It has a power output of 615 W, which is a very high figure for 2025. The solar panel’s efficiency is very high, reaching 22.6% when paired with an inverter, allowing it to be effectively used for earning income under a “green tariff” or for off-grid power supply.
The model is built using the best materials and components available on the photovoltaic market. 132 high-quality silicon cells are secured in a composite alloy frame, 30 mm thick, arranged in 22 rows. Converting solar energy into direct electric current with a maximum voltage of 40.51 V and a current of 15.06 A, they have a low heating level, thereby increasing the performance of each cell. The panel’s surface is reliably protected by double 2.0 + 2.0 mm tempered glass.
The solar panel has passed hail-impact testing with 25 mm hail at a wind speed of 23 m/s. The structure can withstand a snow load of up to 5200 Pa and a wind load of up to 2400 Pa. It is resistant to salt moisture, ammonia, and dust, as confirmed by independent testing.
The device’s IP68 protection class means it is fully protected against dust ingress and can withstand brief immersion in water to a depth of up to 1 meter. Accidental contact between electrical components and people is excluded.
The model is certified under the ISO 9001:2008 and ISO 14001:2004 management systems. Compliance with the industry standards IEC61215 and IEC61730 ensures high quality and safety of the equipment. Independent verification of compliance was carried out by TUV Rheinland.
The device has increased overall dimensions of 2382x1134x30 mm and a light weight of 33.5 kg.
The manufacturer provides a 12-year warranty on the photovoltaic module’s parts and components. The warranty period for linear power output retention is 30 years, with the panel’s power level remaining no lower than 87.4% by the end of this period. In other words, the panel’s degradation over 30 years of operation amounts to only 12.6%.
