The gap depends on which power variant within the 600-620 Wp range is selected. ## About this series The N series G12R TOPCon Bifacial from RedSolar is engineered to make the most of available roof space while delivering dependable long-term energy output. The use of **N-type TOPCon cells** in the rectangular G12R format achieves a favorable power-to-area ratio, which matters when installation space is limited on both pitched roofs and ground-mount systems. The panel features **bifacial technology**, capturing additional energy from the rear side of the module and improving real-world energy yield throughout its service life. The **multi-busbar cell structure** reduces resistive losses and increases resistance to microcracks, resulting in more stable performance over time. A low **power temperature coefficient** means the module retains high efficiency even on hot summer days, which is particularly relevant given Poland's variable solar irradiance conditions. The sleek **black frame** allows for seamless visual integration with roofing in prosumer installations. This series answers the needs of investors seeking a balance between performance, durability, and aesthetics, suited to both residential and commercial segments, while backed by long-term product and power warranties. ## Notable figures - Efficiency of 22.6% matches the \*\*TOPCon 600-650W\*\* median - Power density of 225.8 W/m² matches the \*\*TOPCon 600-650W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 600-650W\*\* panels - Ranked #3658 out of 14005 panels for efficiency in the database ## Questions ### How does N-TOPCon cell technology differ from classic PERC panels? N-TOPCon cells use a thin passivation oxide layer that reduces carrier recombination at the silicon surface, allowing higher efficiency than standard PERC cells. In practice this means more power from the same panel surface, a lower temperature coefficient, and slower power degradation over time, resulting in greater real-world energy yield over the system's lifetime. ### Are N series G12R Bifacial panels suitable for pitched roof installation? Yes, the rectangular G12R format was designed for efficient use of pitched roof surfaces, where the power-to-area ratio matters most. The black frame also allows for a more aesthetic integration with roofing materials. However, the full potential of bifacial technology is best realized with installations that allow reflected light underneath the module, such as flat roofs or ground-mounted systems. ### How much extra energy does bifacial technology actually deliver in these panels? The rear-side energy gain depends on ground albedo, mounting height, and tilt angle, typically ranging from a few to just over ten percent more energy compared to a monofacial panel of the same rated power. Best results are achieved with a light-colored surface, such as gravel or white roofing membrane, combined with elevated racking above the ground. ### What warranty comes with RedSolar N series G12R TOPCon Bifacial panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means the module should still produce a defined percentage of its initial rated power after that period, an important factor when calculating long-term return on investment. ### Do 620 Wp panels require a special inverter or mounting structure? 620 Wp modules are larger and heavier than typical residential panels, so they require a properly sized mounting structure that accounts for higher load and mounting point spacing. The inverter should be selected for compatible string voltage and current per the datasheet, though the N-TOPCon technology itself does not require a dedicated inverter type and works with standard string inverters on the market. ### How do N series G12R TOPCon Bifacial panels perform in high summer temperatures? Thanks to the low power temperature coefficient typical of N-TOPCon technology, these panels lose less power as operating temperature rises compared to older P-type cells. This matters especially in summer, when module surfaces can heat up significantly, and the improved temperature resilience results in more stable energy yield on hot days. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/175280184008777xrf6-21aba563a53d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +40 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +35 W, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -50 W, lighter, +2.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +30 W, lighter, +2.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR8-66HVD-660M](https://comparepv.com/panel/longi-lr8-66hvd-660m) | 660 W | +50 W, cooler, +1.8 pp | | [RedSolar CETC-600TR(GDF)/132](https://comparepv.com/panel/redsolar-cetc-600tr-gdf-132) | 600 W | -10 W, -0.4 pp | | [RedSolar CETC-605TR(GDF)/132](https://comparepv.com/panel/redsolar-cetc-605tr-gdf-132) | 605 W | -0.2 pp | | [RedSolar CETC-615TR(GDF)/132](https://comparepv.com/panel/redsolar-cetc-615tr-gdf-132) | 615 W | Very close match | | [RedSolar M10R-620TR](https://comparepv.com/panel/redsolar-m10r-620tr) | 620 W | +10 W, hotter, +0.3 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +90 W, cooler, +2.4 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +85 W, cooler, +2.3 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +60 W, lighter, +2.2 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +60 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/redsolar-cetc-610tr-gdf-132 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
