About product

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. Novel design solutions allow this panel to look as well as it performs. This model is just 1.18" in depth and is jet black with a sleek finish. The panel's functionality and durability are not affected by its aesthetic appeal though. GSTAR provides an industry-leading 30-year linear power warranty and a 25-year product warranty.

  • 108 half-cut TOPCON N-type cells
  • 440 W nameplate capacity
  • 22.53% efficiency
  • 1500 V DC maximum system voltage
  • MC4-EVO2 connectors
  • 25 years of product and 30 years of linear power 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 black 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.

Stunning black aesthetics

The sleek, all-black aesthetics of the panel will complement any rooftop. By using a variety of treatments and selection criteria, the producer guarantees high quality cell color. Engineers at GSTAR employ smaller gauge wires to link the cells together, creating a seamless appearance.

High-efficiency N-type and TOPCon solar modules from Singapore's vertically integrated manufacturer

G-Star Pte Ltd, founded in 2019 and headquartered in Singapore, is committed to being a trusted global new energy solution provider with a focus on both PV material manufacturing and PV system services. The company specializes in photovoltaic power generation solutions, realizing vertically integrated R&D, design, production and sales from silicon wafers, cells to modules.

G-Star maintains a global strategy with a "1+N" model, one headquarters in Singapore, with N bases covering the United States, China, India, Mexico, Thailand, Indonesia, Laos, the Philippines, and Egypt. By 2025, G-Star's integrated production capacity in Southeast Asia is expected to reach 3GW, with total capacity reaching 17.5GW.

Why Choose G-Star Solar?

🏭 Manufacturing Excellence

G-Star's PV material manufacturing business primarily focuses on the production and processing of silicon materials, including silicon pulling and N-type silicon wafers, as well as metal materials production, including frames and mounting systems. The company controls every step of production which often means better quality control.

🌏 Global Supply Chain

G-Star Solar has established a "vertically integrated" PV production base with facilities in Thailand, Indonesia, Laos, the Philippines, and Egypt. Since it is a Singaporean brand, extra import tariffs for Chinese solar panels from the American government do not affect them and make the panels more affordable for US citizens.

🔬 Technology Innovation

G-Star Solar Panel Technologies Explained

N-Type vs P-Type Cell Technology

P-type solar cells use boron-doped silicon as their base material and have been the industry standard for decades because they were cheaper to produce and the manufacturing process was well-understood. However, N-type cells offer superior performance with less light-induced degradation and better efficiency retention over time.

TOPCon Bifacial Solar Panels

The gstar 425w topcon bifacial solar panel represents cutting-edge technology in the g star solar lineup. The Gstar GSD7S54T 108 cell panels, 425 bifacials sure look interesting, offering enhanced energy generation from both sides. Users report that the GStar 425W panel is quite good and very light (45 pound).

Advanced Manufacturing Features

At RE+2024 Solar Exhibition, G-Star made a prominent appearance with its full suite of photovoltaic supply chain solutions, showcasing the highly anticipated CleanEdge and LightEdge products, which captured significant attention from attendees.
