The RS8V-M-DG series consists of bifacial, double-glass modules engineered for installations where long-term energy yield stability and resilience under harsh operating conditions matter most. The panels use N-type TOPCon cells with half-cut technology and multi busbar interconnection, which reduces internal power losses and improves the module's resistance to microcracks and busbar breakage. Thanks to a double tempered glass layer with high light transmittance and an anti-reflective coating, the series delivers improved performance in low-light conditions, translating into higher real-world energy harvest on cloudy days and during morning or evening hours. The modules are PID-resistant, limiting power degradation over time and contributing to a lower LCOE for the installation. The construction is certified for high wind and heavy snow load resistance, as well as exposure to salt mist and ammonia, making it well suited for both coastal and agricultural installations. The RETIE version meets the requirements of the Colombian market. This is a solution for investors and installers seeking durable, high-performance panels for commercial and industrial projects, where a predictable return on investment over a 30-year linear power warranty is a key priority.

Common questions

6 answered
How does N-TOPCon cell technology in the RS8V-M-DG panels differ from classic PERC cells?
N-TOPCon cells use an additional passivation layer that reduces electron recombination and increases both voltage and module efficiency compared to PERC. In practice this means higher power output from the same panel surface area, lower annual degradation, and better performance in high temperatures. For investors, this translates into higher energy yield and a lower LCOE over the system's operating life.
Do the bifacial RS8V-M-DG panels require special mounting?
Yes, to fully exploit dual-sided energy generation, panels are best mounted on racking that elevates them above the surface, such as flat-roof structures or ground-mounted trackers with a light or reflective surface underneath. Standard pitched-roof installation is also possible, but rear-side gain will be limited due to reduced clearance and light reflection.
What warranty does Resun Solar offer on the RS8V-M-DG series, and what does it cover?
The manufacturer provides a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty. This means a gradual, predictable power degradation curve spread over three decades, allowing investors to precisely plan ROI — an important factor for commercial projects financed through loans or leasing.
Are RS8V-M-DG modules resistant to PID, and what does that mean in practice?
Yes, the series is certified PID-resistant, meaning it resists potential-induced degradation, which in unprotected panels can cause power losses of over ten percent within the first few years of operation. PID resistance keeps RS8V-M-DG modules performing stably throughout their service life, which is especially important in large installations with high system voltage across module strings.
Are RS8V-M-DG panels suitable for coastal or agricultural installations?
Yes, the double-glass construction is certified for resistance to salt mist and ammonia exposure, making it suitable for both coastal installations and agricultural sites, such as those near livestock barns or manure storage. The panels also carry certifications for high wind load and heavy snow load resistance, increasing their versatility in demanding climates.
What is the maximum power output of a single RS8V-M-DG panel?
Panels in the RS8V-M-DG series reach a maximum power output of up to 440 Wp. The combination of N-TOPCon half-cut cells with multi-busbar interconnection reduces internal losses and delivers high module efficiency while maintaining resistance to microcracks, which matters during transport and installation on large rooftop and ground-mounted systems.
