Middle of its segment, weak in heat
The Axitec AXIbiperfect GXQ TS series consists of advanced bifacial Glass-Glass modules that redefine performance standards in demanding installations. The use of cells in N-type TOPCon technology allows for significantly higher efficiency and a radical reduction in power degradation over time, which translates into stable profits for decades. Thanks to their double-sided design, these panels effectively utilize light reflected from the ground, generating additional energy yield, making them an unrivaled choice for rooftop and ground-mounted systems. The double-glass construction ensures exceptional mechanical resistance and full protection against degradation caused by moisture or the PID phenomenon, eliminating common problems of standard modules. This series is dedicated to investors who value fire safety and component longevity. The innovative cell structure optimizes performance in low-light conditions, and low temperature losses guarantee high power production even on hot days. This solution stands out from the competition with an excellent balance between modern aesthetics and heavy-duty construction, offering maximum profitability with minimal risk of failure. By choosing AXIbiperfect GXQ TS, you are opting for future technology that effectively increases self-consumption and the profitability of the photovoltaic system over a long-term horizon.
Ranking
Signals from the data
Commercial, utility-scale, shaded-installations and hot-climate.
Hot climates, roofs where every square metre has to count and weight-limited structures.
Bottom 8% of the TOPCon 700-750 W segment, against a median of -0.290. Ranked 8,005th in the whole database.
Bottom 21% of the TOPCon 700-750 W segment, against a median of 230.2.
Bottom 23% of the TOPCon 700-750 W segment, against a median of 52.9.
N-type TOPCon technology delivers a Pmax temperature coefficient of -0.31%/°C, offering a clear advantage over PERC modules (-0.35%/°C). At a typical cell operating temperature of 65°C during Polish summers, the module loses approximately 1.4% less power relative to PERC, translating into measurably higher energy yield on hot days.
Axitec provides both a 30-year product warranty and a 30-year linear power warranty, guaranteeing ≥87.4% of nominal power after 30 years (linear degradation of ~0.4%/year). The industry standard for PERC modules is 25 years at an 84.8% threshold, making this warranty offering exceptionally strong within the segment.
The dual-glass design (2.0 mm front + 2.0 mm rear) eliminates the risk of potential-induced degradation (PID) and provides a complete barrier against moisture ingress — the primary cause of premature power loss in glass-backsheet modules. This ensures more stable performance throughout the full 30-year operational lifetime.
The bifacial design with a transparent rear glass pane enables absorption of light reflected from the ground surface. The manufacturer rates rear-side bifacial gain at up to 30% (typical real-world bifacial gain is 5–15%, depending on ground albedo and mounting configuration), making the series particularly cost-effective in ground-mounted systems with high-albedo surfaces.
A peak efficiency of 22.86% for the 710 Wp variant positions the series on par with comparable models such as the Phono Solar Draco N-TOPCon (22.86%) and Solarspace SS9-66HD (22.86%). The G12 format with 132 half-cut cells minimizes resistive losses and improves performance under partial shading conditions.
Axitec does not appear on the BNEF Tier-1 Bankable Manufacturers list (confirmed as of Q1 2026), which may complicate or preclude securing non-recourse bank financing for utility-scale PV projects. For residential prosumer systems and small commercial installations this is a non-issue, but for projects exceeding ~1 MWp it may necessitate additional credit enhancements.
The dual-glass design results in a higher unit weight than glass-backsheet counterparts in the same power class — G12 glass-glass modules in the 690–710 Wp range typically weigh 34–38 kg. This may require roof structure reinforcement or heavier-duty racking systems, increasing Balance of System (BoS) costs in rooftop installations.
- At 22.7% efficiency, this panel is on par with typical TOPCon 700-750W modules
- Power density of 226.9 W/m² is 3.2 W/m² below TOPCon 700-750W median (230.2 W/m²) - needs more roof space
- -0.31%/°C temperature coefficient - 0.02pp worse than TOPCon 700-750W median (-0.29%/°C), expect higher hot weather losses
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
- In the top 24% for efficiency among all TOPCon panels
