Middle of its segment, needs the roof space
The GSP7G72M(H) series comprises bifacial single glass solar modules built with half-cut mono PERC cells and 10BB busbar technology. By splitting cells in half and reducing resistive losses, the panel delivers a lower risk of hot spots and more stable performance even under partial shading. The rear side captures additional reflected radiation from the ground, resulting in increased rear-side energy yield depending on installation conditions and surrounding albedo. This makes the series especially well suited to installations over bright, reflective surfaces - light-colored roofing, facades, or ground-mount farms with high-albedo terrain. The reinforced frame and structure are engineered for enhanced mechanical load resistance, allowing installation in regions with heavy wind and snow loads. The IP68-rated junction box provides high resistance to moisture and contaminants, extending trouble-free operation of the array. The GSP7G72M(H) series is a solid choice for both commercial and residential investors seeking panels that combine durability, low long-term power degradation, and installation flexibility across varied site conditions.
Ranking
Signals from the data
Utility-scale, commercial and shaded-installations.
Roofs where every square metre has to count and tight roof space.
Bottom 15% of the PERC 500-550 W segment, against a median of 209.0.
Bottom 17% of the PERC 500-550 W segment, against a median of 20.90%.
The reinforced anodized aluminum alloy frame withstands snow loads up to 5400 Pa and rear wind loads up to 2400 Pa, matching or exceeding the typical segment benchmark of 5400/2400 Pa and enabling installation in regions with high wind and snow loads.
Splitting mono PERC cells into halves combined with 10-busbar technology reduces resistive losses and hot-spot risk, while improving module performance under partial shading and low-irradiance conditions.
Efficiency in the 20.52-21.29% range is on par with leading peer comparables in the 530-550 Wp segment, such as the IBC Solar 182M Half Cell (21.28%) and Goldi Solar GS10-B144-TF (21.3%).
The single-glass bifacial construction captures additional energy reflected off the ground from the rear side of the module, which is particularly beneficial on light-colored roofs, facades, or ground-mount installations with high-albedo terrain.
The IP68-rated junction box provides high resistance to moisture and contamination, reducing the risk of electrical connection failures under demanding operating conditions.
G-STAR does not appear on the BloombergNEF Tier 1 list, unlike some competitors in the 530-550 Wp segment. This may translate into higher project financing risk with banks and less certainty about the manufacturer's production scale and supply chain stability.
The 12-year product warranty falls below the current premium-segment standard, where Tier 1 manufacturers (e.g., IBC Solar - 25 years) typically offer 25-year materials and workmanship coverage, increasing long-term servicing risk exposure for the investor.
- At 20.5% efficiency, this panel is on par with typical PERC 500-550W modules
- At 205.2 W/m², this panel generates 3.8 W/m² less per unit area than PERC 500-550W median (209.0 W/m²)
- At -0.35%/°C, hot weather performance is typical for PERC 500-550W panels
- 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces
- Ranked #11244 out of 14005 panels for efficiency in the database
