GSTAR Solar 550W Solar Panel 144 Cell Bifacial GSD7G72M-550WT Commercial 720 panels per Container (Truckload)

GSD7G72M-550WT is part of the GSD7G72M Series — one of the most recent made by GSTAR. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. GSTAR made solar cells in GSD7G72M-550WT two times smaller than the standard size, thus reducing power loss and improving low-light behavior. Not surprisingly, the efficiency of this module is quite high – 21.29%. 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. GSTAR provides an industry-leading 30-year performance warranty and a 12-year product warranty.

Increased efficiency of up to 21.29 percent

GSD7G72M-550WT ensures maximum power production. The combination of PERC technology and a powerful antireflective coating results in 21.29 percent module efficiency. This is much greater than the average, resulting in significant extra savings over the years of production.

Heat-resistant performance

This module makes the heat less dangerous since it has one of the lowest temperature coefficients in the market, losing just -0.31% of efficiency for every 1.8°F over 77°F.

Quality and reliability

GSD7G72M-550WT is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.

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 30th year will not surpass 0.45%. After 30 years, the module will still produce more than 84.95% of its initial output.

Certified for the most challenging environmental conditions

GSD7G72M-550WT is resistant to PID, salt, acid and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 2400 Pa on the back. Such robustness is mainly due to the 1.38" thick anodized aluminum alloy frame and a layer of protective glass.
