This may complicate access to bank financing for institutional or debt-financed projects. - **Shorter product warranty than N-type leaders** - The 15-year product warranty reflects an older-generation standard, while leading N-type manufacturers (e.g., LONGi, Trina Vertex N) now offer 25-year product warranties alongside the same 30-year power warranty. ## About this series The Powitt Solar G12 MONO MODULE N-TYPE series is an advanced solution based on **N-type silicon cells** that redefine efficiency standards in modern photovoltaics. Thanks to the use of wafers with an impressive 210 mm size, these modules offer significantly higher power density, which translates into real savings during installation and a smaller number of required structural components. Innovative **SMBB technology (Super Multi-Busbar)** effectively reduces resistive losses and minimizes the risk of micro-cracks, ensuring stable operation for decades. A key advantage of this series is **minimal light-induced degradation**, which allows maintaining high energy efficiency even after many years of intensive use. These panels are an ideal choice for investors seeking maximum yield from limited roof or ground space, especially in demanding conditions with lower sunlight. The G12 series stands out from the competition with an excellent **temperature coefficient**, guaranteeing efficiency on hot days when traditional modules lose power. This is a professional solution for industrial projects and demanding residential installations where the priority is the lowest cost of energy (LCOE) and the highest technological reliability. ## Notable figures - Efficiency of 22.4% is 0.9pp below the \*\*N-type 650-700W\*\* median (23.3%) - 223.7 W/m² power density is 9.5 W/m² below \*\*N-type 650-700W\*\* median (233.2 W/m²) - requires larger installation area - At -0.30%/°C, hot weather performance is typical for \*\*N-type 650-700W\*\* panels - At 37.9 kg, this panel is 4.4 kg heavier than the \*\*N-type 650-700W\*\* median (33.5 kg) - more demanding for installation crews - #4970 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### Is the Powitt Solar G12 MONO MODULE N-TYPE series still available for purchase? The Powitt Solar G12 MONO MODULE N-TYPE series has been discontinued and is no longer actively offered by the manufacturer. If you need similar performance — N-type technology with 210 mm wafers — contact your distributor about currently available alternatives or newer Powitt Solar series with comparable power output and specifications. ### What does the bifacial design offer in the Powitt Solar G12 N-TYPE panels, and how much extra energy can you expect? The bifacial G12 N-TYPE module generates power not only from the front side but also from reflected irradiance off the ground (albedo). In ground-mount or light-colored rooftop installations, the rear-side gain is typically 5–15% above the rated 720 Wp output. Actual yield depends on tilt angle, mounting height above ground, and ground surface reflectivity. ### What warranty covers the Powitt Solar G12 MONO MODULE N-TYPE panels? The manufacturer provides a 15-year product warranty covering mechanical defects and workmanship, plus a 30-year linear power output warranty. Over three decades, the panel should retain at least the minimum power percentage specified in the datasheet. This is among the longer warranty standards available for modules in this class, making it especially attractive for projects with long investment return horizons. ### Why are N-type cells in the G12 series better than common P-type PERC? The N-type cells used in the G12 MONO MODULE series show significantly lower light-induced degradation (LID) compared to P-type PERC cells, meaning the panel loses minimal power during the first weeks of operation. N-type also achieves a better temperature coefficient (approximately −0.30%/°C), resulting in noticeably higher energy production on hot summer days when conventional modules lose efficiency more sharply. ### Does the large 720 Wp G12 module fit standard inverters and rooftop racking systems? G12 modules at 720 Wp, based on 210 mm wafers, are significantly larger and heavier than typical 400–500 Wp panels. Before purchasing, verify that your chosen inverter — particularly its MPPT voltage range — supports the higher Voc resulting from stringing these large modules. Your system designer should also confirm that the roof structure can handle their physical dimensions and weight. ### What is SMBB technology in the Powitt Solar G12 panels and does it affect long-term durability? SMBB (Super Multi-Busbar) replaces a few thick busbars with a dozen or more thin current-collecting wires across the cell surface. This distributes mechanical stress more evenly, significantly reducing the risk of microcracks during transport and thermal cycling. The result is lower annual power degradation and better operational stability throughout the entire period covered by the 30-year power warranty. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/50373870267dbad79be02e-3ecbc7723423.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -45 W, 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 | | [Powitt Solar PW-66M690HG12-BD](https://comparepv.com/panel/powitt-solar-pw-66m690hg12-bd) | 690 W | Very close match | | [Powitt Solar PW-66M700HG12-BD](https://comparepv.com/panel/powitt-solar-pw-66m700hg12-bd) | 700 W | Very close match | | [Powitt Solar PW-66M705HG12-BD](https://comparepv.com/panel/powitt-solar-pw-66m705hg12-bd) | 705 W | +10 W, +0.3 pp | | [Powitt Solar PW-66M710HG12-BD](https://comparepv.com/panel/powitt-solar-pw-66m710hg12-bd) | 710 W | +15 W, +0.5 pp | | [Powitt Solar PW-66M715HG12-BD](https://comparepv.com/panel/powitt-solar-pw-66m715hg12-bd) | 715 W | +20 W, +0.6 pp | | [Powitt Solar PW-66M720HG12-BD](https://comparepv.com/panel/powitt-solar-pw-66m720hg12-bd) | 720 W | +25 W, +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/powitt-solar-pw-66m695hg12-bd 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.
