Efficiency leader, no clear weak spot
RedSolar's N series delivers M10 TOPCon Bifacial modules built for installations where squeezing maximum energy yield out of every square meter of roof or ground truly matters. The use of N-type cells with TOPCon technology, combined with a half-cut cell layout and multi busbar interconnection, results in higher efficiency and better performance under partial shading, while reducing the risk of hot spots. The module's dual-sided, bifacial design captures light reflected from the ground, meaningfully boosting total energy output, especially in installations over bright surfaces or ground-mounted systems. These panels stand out for their low first-year degradation rate and a stable, linear power decline over subsequent years, translating into a predictable LCOE and stronger returns over the system's full lifetime. PID resistance and a robust mechanical build make the N series a dependable choice for both commercial installers and solar farm investors who expect reliability and long-term warranty coverage. It's a solution for anyone looking to maximize energy production without compromising on durability or system safety.
Ranking
Signals from the data
Utility-scale and commercial.
Top 5% of the TOPCon 550-600 W segment, against a median of 22.44%. Ranked 1,744th in the whole database.
Top 7% of the TOPCon 550-600 W segment, against a median of 224.4. Ranked 1,758th in the whole database.
The N series' peak efficiency (23.03%) matches the best peer comparables — Solarspace Lumina II (23.03%) and Heliene 144HC (23.02%) — and clearly outperforms Sunova TS-BW78 (21.3%) at the same 595 Wp power rating.
N-TOPCon cells in a half-cut, multi-busbar layout deliver lower LID degradation and better performance under partial shading, reducing hot-spot risk compared to older PERC panels.
The double-sided module design captures light reflected off the ground, meaningfully increasing total energy production, especially in ground-mount installations on bright surfaces or freestanding structures.
The linear power degradation warranty over 30 years ensures predictable LCOE across the module's operating life, a key factor for utility-scale investors calculating long-term ROI.
6 power variants spanning 570-595 Wp allow flexible matching to available roof or ground area, while PID resistance improves reliability in demanding operating environments.
A 12-year product warranty is shorter than the 15-25 year standard offered by leading tier-1 manufacturers (e.g., JinkoSolar, LONGi, Trina Solar), which can matter when comparing total risk cost in commercial projects.
Unlike some peer comparables, RedSolar's presence on the BloombergNEF Tier-1 list could not be verified from publicly available data, which may complicate bank financing for projects requiring this certification.
- At 23.0% efficiency, this panel is 0.6pp above typical TOPCon 550-600W modules (median: 22.4%)
- Power density of 230.3 W/m² packs 5.9 W/m² more into the same footprint vs TOPCon 550-600W median (224.4 W/m²)
- At -0.29%/°C, hot weather performance is typical for TOPCon 550-600W panels
- In the top 12% for efficiency among all TOPCon panels

Datasheet charts
Measured curves published by RedSolar in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 595 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
Model: bifaciality × albedo × 0.6 view factor. A first-order estimate, not a yield simulation.
