Light for its output, short guarantee
The Longi Solar Hi-MO X6 Explorer (LR5-72HTH 565~585M) was designed with the goal of maximizing yield from every square meter - without compromising on aesthetics and durability. Its key advantage is the HPBC (Back Contact) technology, which means the electrical contacts are moved to the rear of the cell. This results in a “cleaner” front side of the module, and limits losses from shading in the wiring paths, translating to more stable performance in real-world conditions - even under poorer light, high temperatures, or partial soiling.
In practice, this is a series for investors who wish to maximize production in space-limited installations and simultaneously reduce the number of panels needed to achieve a certain power output. These modules will perform particularly well in commercial and industrial installations, on rooftops with complex geometries, and in projects where cable and construction costs matter. An additional asset is good performance in heat and enhanced mechanical durability, which is crucial under wind and snow loads.

Top 15% of the 470-670 W band, against a median of 52.7.
Bottom 10% of the 470-670 W band, against a median of 30 yrs.
Electrical contacts are moved to the rear of the cell, eliminating visible fingers and busbars on the front side. This reduces shading losses from the metallization grid, improves module aesthetics, and limits the impact of partial soiling on energy yield.
The 21.9-22.6% efficiency range is essentially on par with the best N-type competitors in this power class (Hanersun Hitouch 5N 22.65%, Risen RSM144-9 22.6%, Q-SUN Qrystal N8 22.65%), confirming the series is not technologically behind the market leaders.
Modules rated at 565-585 Wp reduce the number of panels needed to reach a given installed capacity, lowering mounting structure, DC cabling, and labor costs - particularly valuable in commercial and industrial projects with limited roof area.
LONGi Solar has operated since 2000 and is classified as a Tier-1, bankable manufacturer, which eases project financing through banks and investment funds and increases confidence in the durability of the factory warranty.
A power temperature coefficient of -0.29%/°C is more favorable than the -0.35% to -0.40%/°C typical of older PERC modules, resulting in lower production losses at high operating temperatures, such as during summer months.
The 15-year product warranty and 25-year power warranty fall below the current market standard for top-tier TOPCon panels (Jinko Tiger Neo, Trina Vertex S+, JA Deep Blue), which now offer 25-year product warranties and 30-year power warranties with an 87.4% output floor.
The module has a monofacial (single-sided) design, while some competing 585 Wp N-type series (e.g., Risen RSM144-9-560-585BNDG) are offered in bifacial versions that capture additional rear-side energy yield in ground-mount or carport installations.
Independent reviews of HPBC-based Hi-MO series indicate a higher price versus comparable TOPCon panels of similar power and efficiency, which can extend the payback period for typical residential/prosumer installations.
