Longi Solar LR5-72HBD-555M Solar Panel, 555 W

Description

Single-crystal bifractional(two-sided) solar panel LR5-72HBD-555M It is used in grid-connected, hybrid, or off-grid solar power plant systems. It has a power rating of 555 watts, which is very high a benchmark for 2023. The photovoltaic module’s efficiency is 21.51 TP3T when paired with an inverter, allowing it to be used effectively to generate revenue under «green tariff» programs or for off-grid power supply.

The model was built using the best materials and components available on the photovoltaic market. 144 high-quality silicon cells They are mounted in a 30-mm-thick composite alloy frame, arranged in 24 rows. By converting solar energy into direct current with a maximum voltage of 42.10 V and a current of 13.19 A, they generate minimal heat, thereby increasing the efficiency of each cell. The panel’s surface is reliably protected by 3.2-millimeter tempered glass. 

The structure is capable of withstanding snow loads of up to 5,200 Pa and wind loads of up to 2,400 Pa. It is resistant to salt spray, ammonia, and dust, as confirmed by independent testing.

The device's IP68 protection rating means that it is completely protected against dust ingress and can withstand brief immersion in water to a depth of up to 1 meter. Accidental contact between the electrical components and a person is prevented.

The model is certified under ISO management systems. TÜV Rheinland conducted an independent conformity assessment.

The device has standard dimensions of 2278 × 1134 × 30 mm and weighs only 31.8 kg.

Advantages of the Longi Solar LR5-72HBD-555M solar panel:

• The efficiency is higher than 21.51 TP3T, which is one of the highest figures today.

• The module is part of the Hi-MO 5 series, which features «smart soldering.» This reduces the distance between the solar cells and maximizes light capture.

• The panel has 9 conductive tracks

• Thanks to Bifical technology, electricity generation increases by 5–30% (because the back side of the panel also generates power—sunlight is reflected off the ground or the surface it covers).

• Photovoltaic modules with Bifical technology are more efficient in terms of electricity generation per square meter.

• Thanks to Low LID Mono PERC technology: degradation in the first year of operation is <2%; from the 2nd to the 25th year, it is no more than 0.55%;

• Optimized standard M10 silicon wafers doped with gallium (182 mm) for the manufacture of a P-type mono-PERC module with a low cover, enhanced attenuation and power output, as well as long-term reliability.

• Low thermal coefficient and improved performance in low-light conditions.

• Half-cell technology.

• The 35-mm frame can withstand snow and wind loads of up to 5,400 Pa.

The manufacturer provides a 12-year warranty on the parts and components of the photovoltaic module. The warranty period for maintaining linear output performance is 25 years; at the end of this period, the panel’s power output will be no less than 84.95 %.
