The Kensol PERUN GLASS DUO MNHTR2-BI includes a 30-year product warranty and a 30-year linear power output warranty. This means the manufacturer guarantees both the mechanical integrity of the module and a defined minimum power output level for three full decades. A combined 30-year warranty is among the longest offered in the PV market and reflects the premium build quality of this series. ### What does the glass-glass construction of the PERUN GLASS DUO mean for long-term durability? In the PERUN GLASS DUO MNHTR2-BI, the solar cells are encapsulated between two tempered glass panes instead of a conventional backsheet. This eliminates delamination and microcrack risks while providing full protection against potential-induced degradation (PID). The dual-glass structure significantly extends module lifespan under demanding conditions such as high humidity, coastal salt air, or wide temperature swings. ### Do Kensol PERUN GLASS DUO MNHTR2-BI panels perform well in winter or low-light conditions? Yes. The N-type TOPCon cells in the PERUN GLASS DUO MNHTR2-BI deliver an exceptionally low temperature coefficient and high sensitivity to diffuse irradiance. Under overcast skies or weak winter sunlight the modules generate more power than comparable PERC panels. In climates with long cloudy seasons this advantage translates into a measurably higher annual energy yield for the entire installation. ### How much extra energy does the bifacial design of the PERUN GLASS DUO MNHTR2-BI actually produce? Bifacial operation allows the PERUN GLASS DUO MNHTR2-BI to generate electricity from both direct front-side irradiance and light reflected from the ground surface (albedo gain). Depending on substrate reflectivity — light gravel, snow, or a bright rooftop membrane — the rear-side contribution typically adds a few to over ten percent on top of what a monofacial 460 Wp module of equivalent nameplate power would produce. ### Is the Kensol PERUN GLASS DUO MNHTR2-BI suitable for large utility-scale solar farms or only for residential use? The PERUN GLASS DUO MNHTR2-BI is designed for both residential prosumers and utility-scale PV farms. The low annual degradation rate of N-type TOPCon cells is critical for LCOE calculations in commercial projects, and the bifacial design is especially cost-effective in open-field installations with high ground albedo. With Kensol headquartered in Poland, warranty service and logistics are straightforward for European projects. ### How does the Kensol PERUN GLASS DUO MNHTR2-BI differ from standard monofacial PERC modules? Compared to conventional monofacial PERC panels, the PERUN GLASS DUO MNHTR2-BI delivers higher efficiency through N-type TOPCon cells, a lower temperature coefficient that reduces summer power losses, and additional rear-side energy harvest from bifacial operation. Replacing the backsheet with a second glass pane eliminates microcracks and delamination, substantially extending system lifespan relative to standard PERC modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/KS450MNHTR2-BI-Karta-katalogowa-KS450MNHTR2-BI-PL-548ae4458d00.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, lighter, +2.5 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, lighter, +2.5 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, lighter, +2.5 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, lighter, +2.5 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.5 pp | | [Kensol KS430MNHTR3-BI](https://comparepv.com/panel/kensol-ks430mnhtr3-bi) | 430 W | Hotter, lighter, -0.3 pp | | [Kensol MNHTR2-BI-440](https://comparepv.com/panel/kensol-mnhtr2-bi-440) | 440 W | Very close match | | [Kensol MNHTR2-BI-445](https://comparepv.com/panel/kensol-mnhtr2-bi-445) | 445 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, lighter, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, lighter, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +2.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, lighter, +2.7 pp | --- Source: https://comparepv.com/panel/kensol-mnhtr2-bi-435-1 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.
