Longi Solar LR8-66HYD-650M Bifacial Solar Panel

Description

Are you looking for a no-compromise solution to maximize the profits of your commercial solar power plant, or do you want to get the most power out of the roof of your private home? Meet LONGi LR8-66HYD-650M — the flagship bifacial photovoltaic module from the latest product line Hi-MO 9.

Thanks to a revolutionary combination of proprietary silicon wafers TaiRay wafer and advanced reverse-contact cell technology (BC-CELL), this photovoltaic module sets new standards for reliability and performance. It is capable of generating 6.5% more electricity over its entire life cycle, compared to standard panels from previous generations.

The main advantages of solar panels:

• Bifacial Technology (Bifacial Power Generation): Thanks to its double-glazed design (2.0 + 2.0 mm) and a bifaciality index of 70±5%, the panel collects reflected light on its rear side. Depending on the albedo (the surface’s reflectivity), this results in From 5% to 25% of free additional capacity (up to 809 W under ideal conditions!).

• A phenomenal temperature coefficient (-0.260%/°C): Forget about significant power generation losses during the summer heat. Thanks to the BC-CELL structure, the module's operating temperature is significantly reduced, allowing it to operate efficiently even under the scorching sun.

• Rated efficiency 24.1% (efficiency): Every square meter of your roof or structure will generate maximum profit.

• Extremely low degradation: A 30-year linear power output warranty! The power output decline in the first year is less than 1%, and from age 2 to 30—negligible 0.35% annually. Even after 30 years of continuous operation, the panel is guaranteed to produce 88,85% from its original face value.

Key Technical Specifications:

• Rated power (Pmax): 650 watts

• Open-circuit voltage (Voc): 50.01 B

• Short-circuit current (Isc): 4:49 p.m. A

• Voltage at maximum power (Vmp): 41.20 V

• Current at maximum power (Imp): 15.78 A

• Maximum system voltage: 1,500 V (DC)

• Overall dimensions: 2382 × 1134 × 30 mm

• Weight: 33.5 kg

Official warranties from the manufacturer (Tier-1):

• 12 years — A full warranty on materials and workmanship.

• 30 years — Guarantee of linear output power (remaining power of at least 88.85%).

Who is this panel suitable for?

Longi Solar LR8-66HYD-650M Bifacial Solar Panel — is the ideal choice for industrial ground-mounted solar power plants under own consumption, commercial facilities (factories, warehouses) and high-capacity home systems for “Green Tariff”. Thanks to their high string voltage and high current, they integrate perfectly with modern, high-power grid-tied and hybrid inverters (such as Deye, Huawei, and Solis).
