Thanks to the use of **N-Type TOPCon cell** technology, these modules offer higher efficiency and significantly better performance in low-light conditions compared to standard solutions. A key advantage of the series is its **bifaciality**, allowing for the generation of additional energy from reflected radiation, which is particularly effective on light-colored surfaces or ground-mounted installations. This solves the problem of rapid power loss over the years, ensuring a stable energy yield for decades. PERUN GLASS DUO also stands out with the highest class of resistance to fire and mechanical loads, making it an ideal choice for demanding commercial systems and modern single-family homes. Unlike traditional modules with a protective backsheet, the **double glass** construction completely eliminates the risk of micro-cracks and moisture penetration into the laminate. This product is dedicated to investors looking for premium technology that combines innovation with a maximum service life, ensuring safety and a reliable return on investment in the Polish climate. ## Notable figures - Efficiency of 22.0% matches the \*\*TOPCon 400-450W\*\* median - Power density of 220.2 W/m² matches the \*\*TOPCon 400-450W\*\* median - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - #6329 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What is the warranty on Kensol PERUN GLASS DUO solar panels? The Kensol PERUN GLASS DUO series comes with a 30-year product warranty and a 30-year power output warranty. This is among the longest warranty coverage available on the market. The manufacturer guarantees that after 30 years of operation the module will retain at least 87.4% of its initial rated power, making it an exceptionally secure long-term investment. ### Do Kensol PERUN GLASS DUO panels perform well in overcast conditions? Yes. The N-Type TOPCon cell technology used in the PERUN GLASS DUO series delivers significantly better performance under low-irradiance conditions compared to standard PERC modules. In climates with a high number of cloudy days this translates into measurably higher annual energy yield. The double-glass construction also handles frost, moisture, and hail reliably throughout the module's lifetime. ### How does the double-glass construction of PERUN GLASS DUO differ from conventional backsheet modules? Standard modules use a polymer backsheet that is susceptible to microcracks, yellowing, and moisture ingress over time. PERUN GLASS DUO replaces the backsheet with a full tempered glass layer, completely eliminating these failure modes. The result is higher mechanical strength, improved fire resistance class, and a significantly slower degradation rate across the entire service life of the installation. ### Does the bifacial design of PERUN GLASS DUO make sense for a rooftop installation? Bifacial modules deliver the greatest gain in ground-mounted systems with a light-colored albedo surface (gravel, concrete, snow), where the rear side can capture 5–25% additional energy from reflected irradiance. On a pitched roof the gain is smaller but still measurable, especially with a light-colored roof surface or nearby white facades. For maximum bifacial yield, plan for adequate clearance between the module and the mounting surface. ### What is the rated power of a Kensol PERUN GLASS DUO panel, and what system types is it designed for? Modules in the PERUN GLASS DUO series reach up to 460 Wp maximum power output. The series is designed for both modern residential installations and demanding commercial PV systems. The high per-panel power rating means fewer modules are needed to reach a given system capacity, which reduces BoS costs including racking hardware and cabling. ### Is Kensol a Polish brand, and does that matter when buying PERUN GLASS DUO panels? Yes, Kensol is headquartered in Poland. For installers and investors this means faster delivery logistics, shorter lead times, and straightforward warranty claims without dealing with overseas service centers. It also means technical support and documentation are readily available in Polish, which simplifies system design and after-sales service. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Karta-katalogowa-KS440MNHTR3-BI-EN-ebafe9f03639.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +2.5 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +2.5 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, cooler, +2.3 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +2.3 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +2.3 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +2.3 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, cooler, +2.3 pp | | [Kensol KS430MNHTR3-BI](https://comparepv.com/panel/kensol-ks430mnhtr3-bi) | 430 W | -10 W, -0.5 pp | | [Kensol MNHTR2-BI-435](https://comparepv.com/panel/kensol-mnhtr2-bi-435) | 435 W | Cooler, heavier, -0.2 pp | | [Kensol MNHTR2-BI-445](https://comparepv.com/panel/kensol-mnhtr2-bi-445) | 445 W | Cooler, heavier, +0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/kensol-ks440mnhtr3-bi 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.
