Longi Solar LR7-72HVH-640M Solar Panel, 640 W

Description

Longi Solar has released a completely the new Hi-MO X10 series of solar modules and presented the «hybrid passive back-contact» cell technology» HPBC 2.0, which led to a dramatic increase in the efficiency of solar panels.

As for silicon cells, HPBC 2.0 technology uses its own high-quality N-type TaiRay LONGi silicon wafers, which optimize and reduce solar cell degradation, efficiency potential, and resistance concentration.

The following technology is also used: BC-Cell (Back Contact Cell) — is a method of manufacturing solar panels in which all electrical contacts are located on the back side of the cell. This significantly increases efficiency and improves the appearance of the panels. Since the current-carrying paths are on the back side, the front surface of the solar cell is completely free of metal conductors. This increases sunlight absorption and improves efficiency.

Monocrystalline single-sided solar panel LR7-72HVH-640M застосовується в системах мережевих, гібридних чи автономних сонячних електростанцій. Має потужність 640Вт, при габаритах 2382х1134х30мм, що є дуже хорошим показником на 2025 рік. Коефіцієнт корисної дії сонячної панелі є дуже високим і складає аж 23,7 %, ...which, when paired with an inverter, allows it to be used effectively to generate revenue under the «green tariff» program 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 закріплені в рамі з композитного сплаву, товщиною 30мм, у 24 ряди. Перетворюючи енергію сонця на постійний електричний струм з максимальною напругою 44,36 В та силою струму 14,43А, вони мають низький рівень нагрівання, збільшуючи таким чином продуктивність кожного елементу. Поверхня панелі надійно захищена 3,2-міліметровим загартованим склом.

The solar panel withstood a hailstorm with 25-mm hailstones and wind speeds of 23 m/s. 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 the ISO 9001:2008 and ISO 14001:2004 management systems. Compliance with industry standards IEC 61215 and IEC 61730 ensures the high quality and safety of the equipment. TÜV Rheinland conducted an independent conformity assessment.

The device has larger dimensions of 2382 × 1134 × 30 mm and a light weight of 28.5 kg.

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 30 years, and at the end of this period, the panel’s power output will be no less than 88.85%. That is, The panel's degradation over 30 years of operation is only 11.51 TP3T.
