Kensol PERUN GLASS DUO MNHTR2-BI panels are advanced modules based on N-type technology that redefine market standards for durability and efficiency. Their innovative glass-glass design provides uncompromising cell protection against potential-induced degradation (PID) and the harmful effects of atmospheric factors. By fully utilizing bifacial technology, these modules also generate energy from radiation reflected from the ground, which significantly increases total power yield compared to single-sided counterparts. The use of TOPCon cells allows for achieving exceptional efficiency even in low light intensity, offering users energy stability throughout the year. This solution is dedicated primarily to conscious investors looking for premium products that combine elegant design with the highest resistance to material aging. What distinguishes them from the competition is an optimized temperature coefficient, minimizing power drops during summer heat. The PERUN GLASS DUO series is the optimal choice for modern households and large PV farms focusing on maximum longevity of the system. Choosing this model guarantees safe operation for decades and eliminates the problem of cell micro-cracks, ensuring a fast and predictable return on investment.

What owners get
High N-type cell efficiency

Efficiency of 21.8-23% places the PERUN GLASS DUO series clearly above the Zonergy ZPM MH3-72 peer (21.16%) and on par with Risen RSM96-11-440-460BNDG (23%), meaning less roof area is needed for the same output at comparable 435-460 Wp power.

Glass-glass construction with PID protection

The double-glass build eliminates potential-induced degradation (PID) risk and reduces cell micro-crack exposure, a meaningful advantage over cheaper backsheet-based modules still used in parts of the competitive segment.

Full bifacial technology

The active rear side captures reflected irradiance from the ground (bifaciality factor around ~80% per the manufacturer's documentation), delivering a real annual yield uplift versus monofacial panels of the same nominal power.

30/30-year warranty above market standard

A 30-year linear product and power warranty exceeds the segment's typical 12-15 year product / 25-year power coverage, offering longer investment protection than the average tier-1 offering.

Polish manufacturer with EU service base

Kensol, operating since 2014 and headquartered in Poland, provides a shorter logistics chain and local EU-based warranty support, easing enforcement of the 30-year warranty compared to non-European manufacturers.

Trade-offs
No confirmed BNEF Tier 1 status

Unlike the Risen peer (an established BloombergNEF Tier 1 manufacturer), publicly available sources do not confirm Kensol's presence on the BNEF Tier 1 list, which can be a relevant bankability criterion for large bank-financed PV farm projects.

Common questions

6 answered
What warranty does the Kensol PERUN GLASS DUO MNHTR2-BI come with?
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.
