The panels use **N-type TOPCon cells** in a half-cut format (132 pieces, 2x6x11 layout), which reduces resistive losses and improves performance under partial shading conditions. Thanks to **bifacial technology** and a glass-glass construction, the module captures additional energy from reflected light reaching the rear side of the cells, making it especially beneficial for ground-mount installations and light-colored roofing surfaces. The **multi-busbar technology** applied improves current collection and increases the reliability of electrical connections. The panels stand out for their **PID resistance** and very low annual power degradation, ensuring stable energy output throughout the entire service life. The reinforced frame withstands high snow and wind loads, making it suitable for both commercial installations and utility-scale solar farms operating in demanding climate conditions. This is a solution for investors and installers seeking high reliability, a **long linear warranty**, and predictable return on investment in large-scale projects. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*TOPCon 700-750W\*\* modules - 225.3 W/m² power density is 4.9 W/m² below \*\*TOPCon 700-750W\*\* median (230.2 W/m²) - requires larger installation area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 700-750W\*\* panels - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - Ranked #4222 out of 14005 panels for efficiency in the database ## Questions ### How does the RedSolar N series G12 TOPCon Bifacial CETC-700-720T differ from standard PERC panels? N-type TOPCon cells have lower current losses and a lower annual power degradation rate than classic PERC cells. In addition, the bifacial design allows the module to generate energy from its rear side using reflected light, increasing energy yield per installed area, especially over bright ground or in ground-mounted installations. ### What warranty comes with the RedSolar N series G12 TOPCon Bifacial CETC-700-720T panels? The manufacturer provides a 12-year product warranty and a 30-year linear power output warranty. This means the panel maintains a guaranteed, predictable energy output level over three decades, making it easier to plan return on investment for commercial projects and solar farms. ### Are bifacial panels from this series suitable for roof installations or only ground-mount systems? Bifacial technology performs best over bright, reflective surfaces, so it's most commonly used in ground-mount installations, solar farms, and flat roofs with light-colored coverings. On typical pitched roofs with dark shingles, the extra rear-side gain will be limited, but the panel still functions correctly as a standard monofacial module. ### How many cells does the CETC-700-720T(GDF)/132 module have, and how does this affect partial shading performance? The module uses 132 N-type TOPCon half-cut cells arranged in a 2x6x11 configuration. Splitting cells into halves reduces power losses under partial shading, such as from leaves, a chimney, or a neighboring building, since shading half the module has a smaller impact on overall panel performance. ### Are RedSolar TOPCon Bifacial panels resistant to PID degradation? Yes, the N series G12 TOPCon Bifacial line features high resistance to PID (Potential Induced Degradation), the power loss caused by voltage potential differences within an installation. This ensures stable performance throughout the panel's service life, even in large installations with high system voltage. ### What is the maximum power output of the RedSolar N series panel, and what installations is it suited for? The module reaches up to 720 Wp of maximum power. Combined with bifacial technology and a reinforced frame rated for high snow and wind loads, it's well suited to large commercial installations and solar farms, where high per-unit power and lower cost per watt installed matter most. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/17527441131208374ta-230608be3464.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -50 W, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -30 W, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -30 W, lighter, +2.3 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -30 W, lighter, +2.3 pp | | [RedSolar CETC-690T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-690t-gdf-132) | 690 W | -10 W, hotter, -0.3 pp | | [RedSolar CETC-695T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-695t-gdf-132) | 695 W | Hotter | | [RedSolar CETC-705T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-705t-gdf-132) | 705 W | Very close match | | [RedSolar CETC-710T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-710t-gdf-132) | 710 W | +10 W, +0.4 pp | | [RedSolar CETC-715T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-715t-gdf-132) | 715 W | +15 W, +0.5 pp | | [RedSolar CETC-720T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-720t-gdf-132) | 720 W | +20 W, +0.7 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +105 W, cooler, +2.6 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +100 W, cooler, +2.4 pp | --- Source: https://comparepv.com/panel/redsolar-cetc-700t-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, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
