GSTAR 440W Solar Panel 108 Cell Bifacial GSD7S54T-440BT Wholesale 36 panels per pallet

Among the newest offerings of GSTAR, GSD7S54T-440BT is part of the GSD7S54T series. These panels use state-of-the-art technology to achieve high efficiency and dependability.

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 GSD7S54T-440BT two times smaller than the standard size, thus reducing power loss and improving low-light behavior. The efficiency of this model reaches 22.53% — 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. GSTAR provides an industry-leading 30-year linear power warranty and a 25-year product warranty.

Great productivity through the latest innovations

This GSTAR panel provides 440 W power at 22.53% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including TOPCON N-type cell technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.

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.

High quality standards

GSTAR stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Low degradation for increased longevity

In the first year of service, these panels will lose no more than 1% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.4%. After 30 years, the modules will retain more than 87.4% of their initial output.

Improved frame design

GSD7S54T-440BT design makes it suitable for both residential and business rooftops. The use of a strong 1.18" frame composed of anodised aluminium 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.
