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. ## Notable figures - Efficiency of 22.4% matches the \*\*TOPCon 550-600W\*\* median - Power density of 224.5 W/m² matches the \*\*TOPCon 550-600W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 550-600W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - Ranked #4620 out of 14005 panels for efficiency in the database ## Questions ### How much power does the RedSolar N series M10 TOPCon Bifacial panel generate? The maximum output of the N series module is 595 Wp. This is achieved through N-type TOPCon cells combined with a half-cut design and multi busbar interconnection, delivering higher conversion efficiency compared to older PERC panels of similar size. ### What are the benefits of the bifacial design in the N series panels? The bifacial construction allows the rear side of the module to capture light reflected from the ground, roof, or surrounding surfaces. This results in an additional energy yield, especially on light-colored surfaces, gravel, or ground-mounted installations, where reflectivity is higher than on a dark pitched roof. ### What warranty comes with RedSolar N series panels? The manufacturer provides a 12-year product warranty and a 30-year power performance warranty. This means protection against material and workmanship defects for 12 years, while the module is guaranteed to maintain its specified power output level over three decades of operation. ### How does TOPCon technology differ from PERC in RedSolar panels? TOPCon is a newer N-type cell technology that reduces electron recombination through an additional passivation layer on the rear side of the cell. Compared to popular P-type PERC cells, this delivers higher efficiency, lower power degradation over time, and better performance at higher temperatures, resulting in a higher annual energy yield. ### Are N series panels suitable for large commercial installations and solar farms? Yes, the half-cut design with multi busbar cell interconnection and PID resistance make the N series suitable for commercial installers and solar farm investors. The stable, linear power degradation curve makes it easier to forecast LCOE and plan long-term investment returns. ### Do RedSolar N series panels handle partial shading better? Yes, the half-cut design with multi busbar interconnection divides the module into smaller, independently operating electrical sections. This reduces the overall performance loss when part of the panel is shaded and lowers the risk of hot-spot formation, extending the module's lifespan. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/175280228691636bq4y-d54914fab287.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, cooler, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -30 W, lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, lighter, +1.9 pp | | [RedSolar CETC-570T(GDF)/144](https://comparepv.com/panel/redsolar-cetc-570t-gdf-144) | 570 W | -10 W, -0.4 pp | | [RedSolar CETC-575T(GDF)/144](https://comparepv.com/panel/redsolar-cetc-575t-gdf-144) | 575 W | Very close match | | [RedSolar CETC-585T(GDF)/144](https://comparepv.com/panel/redsolar-cetc-585t-gdf-144) | 585 W | Very close match | | [RedSolar CETC-590T(GDF)/144](https://comparepv.com/panel/redsolar-cetc-590t-gdf-144) | 590 W | +10 W, +0.4 pp | | [RedSolar CETC-595T(GDF)/144](https://comparepv.com/panel/redsolar-cetc-595t-gdf-144) | 595 W | +15 W, +0.6 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/redsolar-cetc-580t-gdf-144 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
