LONGI LR4-72HPH 440M (440W) Photovoltaic Solar Panel

Features of LONGI LR4-72HPH 440M Solar Panel:

LONGI is a world-leading brand in the production of photovoltaic cells. The LR4-72HPH 440M is an efficient product with 144 monocrystalline cells, a solid and aesthetically pleasing structure, and excellent photovoltaic performance.

It has achieved notable certifications such as UL 1703, IEC 61215, IEC 61730, and ISO 9001/14001. It is suitable for residential or commercial solar power systems.

Equipped with a robust 3.2mm tempered glass, it provides excellent protection for the cells in harsh weather conditions, while also minimizing dust accumulation on the surface, which could affect the system's performance.

Utilizing mono half-cell technology, it delivers over 22% higher photovoltaic efficiency and reduces the temperature of the panel during operation.

A unique feature of the parallel design is the ability to generate more power compared to other panels in shaded conditions.

The junction box meets IP68 water resistance standards. The high-quality diodes ensure the module runs safely, dissipates heat efficiently, and has a long lifespan.

The 40mm frame is rigorously tension-tested, with meticulous adhesive application, ensuring durability for long-term use. The average load-bearing capacity of the front and back of the panel is 5400Pa and 2400Pa, respectively. The frame color is available in silver or black.

The panel has a lifespan of 25-30 years, with a 12-year technical warranty and a 25-year performance warranty, maintaining over 80% efficiency.
