The Kensol PERUN GLASS DUO panel series is an advanced solution based on a glass-glass construction, which guarantees extreme durability and resistance to degradation caused by atmospheric factors. 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.

What owners get
Efficiency up to 23%, matching market leaders

The 21.52-23% efficiency range puts the PERUN GLASS DUO series on par with leading TOPCon products such as Phono Solar Draco (23.02%) and SunKean SKT440-460 (23.02%), and clearly ahead of Axitec AXIbiperfect GR WB (22.54%).

Glass-glass construction with bifacial technology

The dual-glass design fully eliminates the risk of microcracks and moisture ingress into the laminate, while bifaciality enables additional energy yield from reflected irradiance - especially effective in ground-mount installations and on high-albedo surfaces.

30-year product and power warranty

The manufacturer offers 30 years of warranty on both the product and power output - significantly beyond the standard 12/25-year terms offered by most manufacturers in the segment, reducing long-term investment risk.

N-Type TOPCon cells

N-Type TOPCon technology delivers a lower LID/LeTID degradation coefficient and better performance under low-light conditions and high temperatures compared to older P-type PERC cells.

Polish manufacturer operating since 2014

Kensol is headquartered in Poland and has been active in the market for over a decade, easing logistics, warranty claims, and service compared to imports from Asian suppliers.

Trade-offs
No confirmed BNEF Tier 1 status

Unlike some comparable manufacturers (e.g., Phono Solar), available sources do not confirm Kensol's presence on the BNEF Tier 1 list, which may matter to institutional investors and bank-financed projects when assessing product bankability.

Short market track record for the series

The PERUN GLASS DUO series launched in 2023, so multi-year independent field-test data on real-world power degradation is still limited compared to manufacturers with a longer history in glass-glass TOPCon products.

Notes from the database

Common questions

6 answered
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.
