The RS9H-M-DG series is a bifacial dual-glass photovoltaic module designed for projects where every extra kilowatt-hour of yield matters. The panel is built on N-type TOPCon cells with multi-busbar (MBB) technology, which reduces internal power loss and boosts conversion efficiency compared to conventional PERC designs. The half-cell construction further lowers the risk of failures caused by microcracks and busbar breakage, while effectively mitigating hot-spot issues triggered by partial shading. Thanks to its bifacial dual-glass design, the module captures irradiance from both sides, delivering higher energy yield, especially in ground-mount installations over reflective surfaces. The panel also stands out for its high mechanical load resistance, certified for wind loads up to 2400 Pa and snow loads up to 5400 Pa, and it withstands salt mist and ammonia exposure, making it a solid choice for coastal and agricultural installations. Anti-PID performance combined with low annual power degradation ensures stable energy output throughout the module's service life, backed by a 30-year linear power warranty. This makes the series a strong fit for investors seeking high reliability and reduced LCOE in commercial and industrial-scale projects.

Common questions

6 answered
What is the maximum power output of the Resun Solar RS9H-M-DG panel?
The RS9H-M-DG series reaches a maximum power of up to 720 Wp, with a conversion efficiency above 22%. This is achieved through N-type TOPCon cells with multi-busbar (MBB) technology, which reduce current losses and deliver higher power from the same module surface compared to classic PERC panels.
How does TOPCon technology in the RS9H-M-DG differ from classic PERC panels?
The N-type TOPCon cells used in the RS9H-M-DG feature an additional passivation layer that reduces electron recombination and limits internal power losses. In practice, this means higher efficiency, lower degradation over time, and better performance at high temperatures compared to standard PERC modules, resulting in a higher annual energy yield.
Does the bifacial RS9H-M-DG panel require special mounting to benefit from rear-side light capture?
To fully exploit the bifacial dual-glass design, the panel should ideally be mounted on ground-mount structures or trackers with sufficient clearance beneath the module and over a reflective surface (e.g., white gravel, snow). On a typical sloped roof the rear-side gain will be smaller, but the panel still operates normally and generates power from its front side.
What warranty comes with the RS9H-M-DG solar panels?
Resun Solar provides a 15-year product warranty and a 30-year linear power warranty, meaning a guaranteed, gradual performance decline spread across three decades. This exceeds the market standard of roughly 10-12 years product and 25 years power warranty, reflecting the low annual degradation of the TOPCon cells.
Are RS9H-M-DG panels suitable for agricultural and coastal installations?
Yes, panels in this series are certified resistant to salt mist and ammonia exposure. This makes the RS9H-M-DG well suited for agrivoltaic projects, livestock farms, and coastal installations, where standard panels tend to corrode or degrade faster due to chemical exposure.
What wind and snow loads can the RS9H-M-DG panels withstand?
The panels are certified for wind loads up to 2400 Pa and snow loads up to 5400 Pa, meeting the requirements for demanding climates, including mountainous regions with heavy snowfall. The dual tempered glass construction further increases mechanical strength compared to standard back-sheet designs.
