About product

GSP7G54M(H) is part of the MARS Series — one of the most recent made by GSTAR. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.

Another advantage is the half-cut cell technology. GSP7G54M(H) 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. Given its size and weight, GSP7G54M(H) efficiency of 20.48% is quite impressive. 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. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. GSTAR offers 12 years of product warranty and guarantees 84.95% of original performance after 30 years of operation.

High efficiency of 20.48%

GSTAR MARS panels take full advantage of the company’s technologies that have won GSTAR 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.

Improved efficiency at high temperatures

Greater energy as temperature rises is a mark of a good temperature coefficient. Your panel's efficiency will drop by just -0.29% for every 1.8°F increase over 77°F.

Quality and reliability

GSP7G54M(H) 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 a longer lifespan

These panels will lose no more than 2% 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 0.45%. The module retains over 84.95% of its original output after 30 years. Guaranteed by GSTAR.

A panel that can handle hail, wind and snow

The 1.18" frame built of Black anodised aluminium and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 5400 Pa load, whereas the back side can withstand a 2400 Pa load.

Outstanding all-black design

The panel features all-black design which 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.

GStar Solar panels: Singaporean brand with efficient solar energy solutions

In this section of our website, we present you G-Star Solar panels. G-STAR Group started in Singapore in 2019. They make solar panels and provide solar system services. The company has offices in six places: Singapore (their main office), United States, Taiwan, Thailand, Indonesia, and Laos.

GStar Solar handles everything from developing new products to making and selling them. The company sells their solar products in North America, Europe, Asia-Pacific, and Africa.

Why choose G-Star Solar panels

GStar Solar offers solar panels for all kinds of applications: home, business and utility-scale projects. 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. Finally, GStar solar panels have all the necessary safety certificates for installation, and come with a 25-year warranty for product. The company controls every step of production which often means better quality control.

Benefits of G-Star panels for your business

G-Star solar panels employ p-type cells, n-type cells and NPBC cells. Let us explain what these are.

  • Rapid fulfillment: P-type solar cells use boron-doped silicon as their base material. These cells have been the industry standard for decades because they were cheaper to produce and the manufacturing process was well-understood. However, they have some drawbacks - they're more susceptible to light-induced degradation (LID) and suffer from efficiency losses over time, particularly in hot climates.
  • Speedy delivery: N-type solar cells use phosphorus-doped silicon as their base material. These cells have several advantages over p-type cells: they're less sensitive to light-induced degradation, have better performance in low-light conditions, and generally maintain their efficiency better over time. They also have higher efficiency potential because the phosphorus-doped base material has better electron mobility. While historically more expensive to manufacture, improved production techniques have made n-type cells increasingly competitive.
  • Nationwide reach: In NPBC (N-type Passivated Back Contact) modules, all the metal contacts are moved to the back of the cell, leaving the front surface completely free to capture sunlight. This design eliminates front-side shading losses from metal gridlines and allows for better light absorption. NPBC modules typically achieve higher efficiencies than conventional solar cells, but require more precise manufacturing processes and typically come at a premium price point.

How to select G-Star Solar panels

Looking for solar panels for home? In that case, we recommend solar panels under 500W in power output. They are smaller and less susceptible to wind and hail. For commercial and industrial-scale systems, it makes sense to pick panels that over 500W in power output. For ground-mounted system, consider bifacial solar panels.

Efficiency of solar panels becomes important when you space is limited and you need a powerful system. In this case, look for panels that have over 22-23% efficiency. For hot areas, we recommend panels with HJT cells – they lose less efficiency in hot weather.

What is G-STAR Solar?

G-STAR Solar, officially known as G-STAR Pte. Ltd., is a solar photovoltaic (PV) manufacturer founded in 2019 and headquartered in Singapore. The company focuses on providing smart energy solutions globally, specializing in PV material manufacturing and system services.
