GSTAR 440W Solar Panel 108 Cell All-Black Bifacial GSD7S54T-440BT Wholesale 31 panels per pallet

GSD7S54T-440BT is part of the N-Type Series — one of the most recent made by GSTAR. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Topcon N-Type cell technology ensures excellent power output.

Another advantage is the half-cut cell technology. GSD7S54T-440BT has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity, and better low-light performance. Not surprisingly, the efficiency of this module is quite high – 22.53%. 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. The innovations made the appearance of the panel as impressive as the specs. A mere 1.38" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. GSTAR provides an industry-leading 30-year linear power warranty and a 25-year product warranty.

High efficiency of 22.53 percent

GSTAR N-Type panels fully use the firm's innovations, for which GSTAR has received several distinctions. With Topcon N-Type cell technology, more electricity can be produced per square foot of PV modules. As a result, there will be fewer clamps and racks required during installation. All of which lowers your overall expenses and accelerates the payback period.

Heat-resistant performance

The heat is less of a threat with this module: with one of the lowest temperature coefficients in the industry, GSD7S54T-440BT loses just -0.3% of efficiency for every 1.8°F above 77°F.

Quality and reliability

GSD7S54T-440BT 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, GSTAR is committed to quality, safety, and dependability.

Low degradation for a longer lifespan

These panels will lose no more than 1% of their power output in the first year of service. From the 2nd year to the 30th year, the average annual power decline will be no more than 0.4%. The module retains over 87.4% of its original output after 30 years. Guaranteed by GSTAR.

Enhanced frame design

This model's construction makes it perfect for both residential and business rooftops. Durability and strength are increased by using a strong, robust frame built from black anodised aluminium. A significant snow load of up to 5400 Pa may be supported by the model. The panel's back can support 2400 Pa, assuring that even the strongest winds won't damage your system.

Outstanding all-black design

The panel features an all-black design that looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. GSTAR engineers use thinner wires to connect the cells together, and at a distance, the surface of the modules appears smooth and uninterrupted.
