When one of the world’s largest monocrystalline solar cell manufacturers produce their own module in the latest 120 half cut cell trend, a second look is often worthwhile. Here’s the most intriguing part, it appears LONGi has the pick of the bunch when it comes to solar cell selection.

.

Make and model:  LONGi LR6-60HPH.

Variants:  300 / 305 / 315 / 325 W.

  Efficiency, Performance.

  Durability.

LONGi solar panels, in general, have a proven tendency to produce higher yields (kWh) when compared to similar wattage solar panels within like for like competing module classes. Why so? In a nutshell, beyond rated specifications, not all solar panels are created equal. Therefore, how does the LONGi LR6-60HPH compete in a world where the slightest differences mean everything?

Design.

Embracing the latest innovative solar module trend in a 120 half cut solar cell design, the LONGi LR6-60HPH presents some admirable qualities. In its typical monocrystalline nature, the PERC enhanced five ribbon busbar design could potentially be more potent in a six wire busbar configuration. Beyond such, LONGi’s LR6-60HPH variant works better than many in real-world conditions.

LR6-60HPH Efficiency; Superior
  • 19% Maximum module efficiency.
  • -0.37%°C Temperature coefficient.
  • 0/5W Power tolerance.

Performance.

Backed by a full manufacturer parts & service guarantee for the 25-year period speaks volumes toward manufacturer confidence behind the LONG LR6-60HPH.

Although not the best, the 0.5% annual degradation after the first year 2% degradation is better than most (3% yr-1 & 0.7% p/a). An exceptional performer, the LONGi LR6-60HPH, presents solid performance specifications for any consideration.

LR6-60HPH Performance; Superior
  • 2% degradation in the 1st year.
  • 0.5% degradation per annum.
  • 25-year linear performance warranty.
  • Parts & service performance warranty.

Guarantee.

An inclusive parts and service 10-year product warranty facilitate some additional comfort to an industry average duration. Lacking that of extra length end-user comfort could be solidified with a LONGi approved installer network and potentially greater end-user benefits. Unfortunately, there is no LONGi affiliated or trained installer network.

OVERALL.


The LONGi LR6-60HPH is a superior solar panel in anyone’s language. Could it be better? Absolutely. Given its affordability though there is exceptional value in the technology at hand even if specific criteria elements languish behind the industries best.

One of the better mid-range solar panels available and backed by a company with the pick of the purest foundations. In real-world testing, such purity speaks volumes in overall yield (kWh). If budget restraints present then the LONGi LR6-60HPH is one of the better value 120 half-cell solar modules available which has proven to produce reliable yields over alternative like rated modules. A good solar panel choice for many.
