Multiple Installation Methods

Clamps Rail Installation
Clamps Railess Installation

For metal rooftops, the Galaxy 570W features a clamp-based rail installation that adapts easily to different project needs. With four to six fixing points per module, it ensures a reliable balance between stability and installation efficiency, while integrating seamlessly with standard industrial roofing practices.
For more complex rooftop conditions, the Galaxy 570W supports a rail-less clamping solution combined with mechanical fastening. This method accommodates uneven roof surfaces and suits both new and retrofit projects, while providing enhanced stability in areas with higher wind resistant requirements.

FAQ

Q

How does the N-Type TOPCon technology in the Galaxy series impact Balance of System (BOS) costs for space-constrained projects?

The Galaxy series' N-Type TOPCon technology, with 22.97% module efficiency and 230W/m² power density, reduces module count in space-constrained projects, lowering BOS costs like mounting hardware, DC cabling, and labor, thus boosting ROI.
Q

Does the structural design help reduce subsequent operation and cleaning costs?

Yes, the Galaxy module's flat bottom end frame eliminates the protruding lip, allowing rainwater to flow freely and prevent dirt pooling, thus reducing operation and cleaning costs.
Q

What is the lifecycle performance and long term power degradation rate of the product?

GoodWe Galaxy series offers a 12-year product warranty and 30-year power guarantee, with ≤1% first-year degradation and 0.4% annual decay thereafter for sustained energy yields.
Q

What installation methods does this product support and how does it affect project schedules?

GoodWe Galaxy series supports rail and railless installation via clamp-fixed methods, compatible with standard PV modules and offering an optional connector for roofsheet leveling, which reduces installation time by 20%-30% to accelerate project schedules.
Q

Why is the Galaxy series specifically suited for commercial roofs with limited load bearing capacity?

The Galaxy series BMT-G5/120A module weighs just 6.8±0.4 kg/m², 50% lighter than conventional modules, making it compatible with roofs with load capacity as low as 11 kg/m², eliminating the need for costly structural reinforcements.
