Galaxy Framed Version Uncovered: Technical Insights into High-Power, Full-Screen Modules
February 25, 2026
As commercial and industrial rooftop projects expand, many buildings face constraints such as limited load-bearing capacity, flat roof ballast systems, or high snow-load requirements. At the same time, installers must control installation time and structural costs while ensuring long-term reliability. Conventional high-power modules often increase roof weight and mounting complexity, creating a clear need for a solution that combines high output with optimized weight and strength. To meet this demand, GoodWe has developed the Galaxy Plus(565/570/575W).
The Galaxy Plus(565/570/575W) is specifically designed for commercial and industrial rooftops, offering enhanced performance for metal roofs, flat roofs, and structures with strict load-bearing requirements. Upholding the principles of lightweight design, high reliability, and installation efficiency, it provides a practical and high-performing solution for users.
With evolving application scenarios, the Galaxy series has expanded from the Galaxy Plus frameless module, primarily used for metal roof installations, to the Galaxy Plus(565/570/575W) high-power framed module, capable of covering flat roofs and regions with heavier snow loads. Together, these products offer a comprehensive solution for diverse roof types and environmental conditions.

Key Advantages of Galaxy Plus(565/570/575W)
1. Lightweight Design
Galaxy Plus(565/570/575W) continues the lightweight concept of the Galaxy series. Despite its larger module size and higher power output, its weight is only 6.8 kg/㎡, making it suitable for rooftops with structural load limits within 11 kg/㎡.
Compared with conventional modules weighing 10-15 kg/㎡, Galaxy Plus(565/570/575W) can be installed on roofs with much lower load-bearing capacity. This significantly expands its applicability to lightweight commercial and industrial rooftops where structural reinforcement is difficult or costly.
By reducing roof load while maintaining high power output per module, Galaxy Plus(565/570/575W) enables safe installation and improved system capacity on load-restricted buildings.
2. Full-Screen Design
The Galaxy Plus(565/570/575W) features a full-screen surface design that minimizes dust accumulation by eliminating front-side frame edges. This reduces the frequency of cleaning and lowers long-term operation and maintenance (O&M) costs.
By decreasing soiling losses and reducing manual cleaning requirements, the design directly contributes to lowering the Levelized Cost of Electricity (LCOE). In many commercial and industrial rooftop projects, cleaning typically accounts for a noticeable portion of annual O&M expenses. For example, if a rooftop system requires 2–3 manual cleanings per year due to dust accumulation around frame edges, reducing cleaning frequency by even one cycle annually can cut cleaning-related costs by 30–50%, depending on local labor rates.
In addition to lowering cleaning expenses, reduced soiling losses help maintain more stable power output over time, minimizing performance fluctuations between cleaning cycles. This improves overall annual energy yield and enhances long-term revenue predictability.
By combining lower maintenance frequency with improved energy generation stability, the full-screen design supports long-term operational efficiency and contributes to a more competitive LCOE.
3. High-Power Performance
Galaxy Plus(565/570/575W) features a high-power design, increasing installed capacity per module and reducing the total number of modules required for a given system size.
This not only simplifies installation and shortens construction cycles but also brings tangible cost benefits, including:
Lower Balance of System (BOS) costs due to fewer mounting structures and fittingsReduced racking and support requirementsDecreased electrical wiring and labor costs
Together, these advantages make Galaxy Plus(565/570/575W) ideal for commercial and industrial projects where installation efficiency, speed, and overall project economics are critical.
4. Reliability
Galaxy Plus(565/570/575W) features Stäubli junction boxes and connectors, ensuring secure and stable electrical connections. It has also passed Salt Spray Test Level 6, providing reliable performance in corrosive environments up to 500 m above sea level.
Galaxy Plus(565/570/575W) is mechanically reinforced to withstand extreme environmental conditions:
Certified to handle snow loads up to 5,400 Pa, equivalent to 1.8 m of snow with a density of 300 kg/m³
Certified wind resistance up to 49 m/s
With its strengthened structural design and reinforced frame architecture, Galaxy Plus(565/570/575W) provides enhanced mechanical performance under certified snow and wind load conditions, ensuring long-term system safety, durability, and consistent energy generation.
Product Status and Packaging
Galaxy Plus(565/570/575W) is available for sale and holds TUV and IEC certifications, ensuring international compliance and reliability.
In addition, its efficient packaging supports project logistics, simplifying transport and on-site handling:
Value Proposition for Distributors & Installers
