Hounen Solar 550W Solar Panel 144 Cells Bifacial HNM7-SHDB144-550 Assembled in the USA Commercial 620 panels per Container (Truckload)

HNM7-SHDB144-550 is a model that uses a number of technologies to bring durability and performance to the next level. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

To further boost the performance, Hounen Solar employs half-cut cell technology. Each of the panel’s 144 cells is only half the size of a traditional solar cell. This grants HNM7-SHDB144-550 lower resistive losses and better shade tolerance. The efficiency of this model reaches 21.29% — well above the market’s average. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Hounen Solar provides 12 years of product warranty and guarantees that after 25 years, performance will be at 84.8% or more.

High efficiency of 21.29%

Hounen Solar HNM7-SHDB144-550 panels take full advantage of the company’s technologies that have won Hounen Solar multiple awards. This PERC option offers higher power output per square foot of PV modules. This means quicker installation times and fewer clamps and racks. All of which reduces your overall costs, shortening the payback time.

Better performance at high temperatures

Excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel’s efficiency by only -0.35%.

High quality standards

Hounen Solar strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 25th year will not surpass 0.55%. After 25 years, the module will still produce more than 84.8% of its initial output.

Improved frame design

HNM7-SHDB144-550 design makes it suitable for both residential and business rooftops. The use of a strong 1.38" frame composed of anodized aluminum alloy boosts durability and strength. The model can withstand a significant snow load of up to 5400 Pa. The panel's back can withstand 2400 Pa, guaranteeing that your system will resist even the fiercest winds.
