**N-type TOPCon technology with half-cut and MBB** - The combination of N-type TOPCon cells, half-cut architecture, and multi-busbar (MBB) design reduces resistive losses and hot-spot risk while improving current collection across the cell surface, even at elevated operating temperatures. - **Dual-side energy generation (bifacial)** - The bifacial construction enables additional energy yield from reflected light reaching the module's rear side, which is particularly beneficial for ground-mount, tracker, or high-albedo surface installations - typically 5-15% extra output compared to mono-facial panels. - **High unit power up to 695 Wp** - Maximum power of 695 Wp with efficiency up to 22.37% provides high power density per square meter, translating into lower BoS costs (wiring, mounting structures) per installed watt. - **30-year linear power warranty** - The 30-year power warranty aligns with the standard offered by leading N-type cell manufacturers and exceeds the typical 25-year warranties of older PERC technology, indicating lower annual degradation of the module. - **Low degradation thanks to N-type cells** - N-type cells show lower sensitivity to LID (Light Induced Degradation) than older P-type/PERC technologies, resulting in more stable energy yield throughout the installation's operational lifetime. ## Cons - **Efficiency below top competitors** - Maximum efficiency of 22.37% is lower than comparable models - Sunket SKT680~700M12-132D5 achieves 22.5% at up to 700 Wp, and Sunova TS-BGT66-G12 reaches 22.4% at the same 695 Wp maximum power. - **12-year product warranty - below market trend** - The 12-year product warranty is shorter than the current standard offered by many N-type module manufacturers, where 15 years (and in some cases 20-25 years) is becoming the new norm for this technology class. - **Limited brand recognition and bankability** - RedSolar does not have confirmed presence on publicly available BNEF Tier-1 lists, unlike global brands (e.g., Canadian Solar) offering similar 690-695 Wp N-type bifacial specs. This may matter for bank financing of large commercial projects. ## About this series The RedSolar G12-MBB N-type Mono Bifacial series delivers modern photovoltaic modules that combine N-type TOPCon cells with dual-sided energy generation. The panels use large-format G12 silicon wafers together with a **half-cut** cell architecture, which reduces resistive losses, improves shading tolerance, and lowers the risk of hot spots. The **multi-busbar (MBB)** technology enhances current collection across the cell surface, improving module stability even under high-temperature conditions. Thanks to their **bifacial** design, the panels capture additional energy from reflected light reaching the rear side of the module, making them especially effective on light-colored surfaces, ground-mount installations, or tracker systems. **N-type** cells offer lower degradation over time and reduced sensitivity to LID compared to older cell technologies, resulting in longer service life and more stable energy yield throughout the system's operating period. This series is a strong choice for large commercial installations and solar farms, as well as demanding industrial projects where high power density per square meter and low levelized cost of energy (LCOE) are priorities. The module's robust construction and materials ensure resilience against harsh weather conditions and long-term installation reliability. ## Notable figures - Module efficiency of 22.4% is 0.9pp below average for \*\*N-type 650-700W\*\* panels (median: 23.3%) - At 223.7 W/m², this panel generates 9.5 W/m² less per unit area than \*\*N-type 650-700W\*\* median (233.2 W/m²) - -0.31%/°C temperature coefficient - 0.02pp worse than \*\*N-type 650-700W\*\* median (-0.29%/°C), expect higher hot weather losses - At 38.0 kg (4.5 kg above \*\*N-type 650-700W\*\* median of 33.5 kg), requires checking roof load capacity - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### How do N-type TOPCon cells in the RedSolar G12-MBB panels differ from older P-type panels? The N-type cells used in the G12-MBB series feature lower annual degradation and virtually eliminate LID, which used to reduce output on older P-type panels within the first months of operation. This keeps the module's efficiency higher throughout its service life and enables a longer, more stable power warranty of up to 30 years. ### How much extra energy can I gain from the bifacial design of the G12-MBB panels? The bifacial design lets the rear side of the module capture light reflected off the ground, typically adding a few to over ten percent extra energy yield compared to monofacial panels. Best results come from installation over light-colored gravel, white roofing membrane, ground-mount structures, or trackers with adequate clearance beneath the module. ### What warranty comes with the RedSolar G12-MBB N-type panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 30-year power output warranty. This warranty structure is typical of the latest generation N-type panels and reflects their slower degradation compared to conventional PERC technology. ### Is the 695 Wp RedSolar G12-MBB panel suitable for large-scale solar farms or industrial projects? Yes, with output up to 695 Wp and large G12 wafers, this series is designed for high power density per square meter, lowering installation cost per watt. This makes the panels well suited for large solar farms and commercial projects where minimizing LCOE and reducing the total module count for a given capacity are priorities. ### What is multi-busbar (MBB) and half-cut technology in the RedSolar G12-MBB panels? Half-cut technology splits each cell into two halves, reducing resistive losses and improving resistance to partial shading and the risk of hot spots. Multi-busbar increases the number of current-collecting pathways across the cell surface, improving conductivity and keeping the module's performance more stable even at higher operating temperatures. ### Do RedSolar G12-MBB panels perform well in high summer temperatures? Yes, the multi-busbar technology combined with the half-cut architecture helps the module dissipate heat more effectively and maintain more stable output at high temperatures than traditional panels. N-type cells also have a lower efficiency drop as temperature rises compared to older P-type technology, resulting in more predictable energy yield on hot days. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/17365113633761derox-4869f4037577.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -50 W, lighter, +2.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.6 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +2.4 pp | | [RedSolar CETC-690T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-690t-gdf-132) | 690 W | Very close match | | [RedSolar CETC-700T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-700t-gdf-132) | 700 W | Cooler | | [RedSolar CETC-705T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-705t-gdf-132) | 705 W | +10 W, cooler, +0.3 pp | | [RedSolar CETC-710T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-710t-gdf-132) | 710 W | +15 W, cooler, +0.5 pp | | [RedSolar CETC-715T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-715t-gdf-132) | 715 W | +20 W, cooler, +0.6 pp | | [RedSolar CETC-720T(GDF)/132](https://comparepv.com/panel/redsolar-cetc-720t-gdf-132) | 720 W | +25 W, cooler, +0.8 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +110 W, cooler, +2.7 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +105 W, cooler, +2.5 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +100 W, cooler, +2.4 pp | --- Source: https://comparepv.com/panel/redsolar-cetc-695t-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.
