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. - **30-Year Product and Power Output Warranty** - 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. - **Glass-Glass Construction Eliminates PID and Moisture Ingress** - 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. - **Bifacial Gain of Up to +30% from the Rear Side** - 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. - **Module Efficiency of 22.21–22.86% — Top of Segment** - 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. ## Cons - **Not Listed as a BNEF Tier-1 Manufacturer** - 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. - **Higher Module Weight Due to Glass-Glass Construction** - 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. ## About this series The Axitec AXIbiperfect GXQ TS series consists of advanced **bifacial Glass-Glass** modules that redefine performance standards in demanding installations.

The AXIbiperfect GXQ TS series is covered by both a 30-year product warranty and a 30-year power output warranty. Axitec guarantees that after 30 years of operation, the module will retain at least 87.4% of its nominal power output. This is one of the longest warranties available in the photovoltaic panel market, providing genuine investment security across three full decades of operation. ### What does TOPCon N-type cell technology mean in the AXIbiperfect GXQ TS panels, and why is it superior to standard PERC? TOPCon N-type is a next-generation cell technology in which a tunnel oxide passivation layer reduces charge carrier recombination. The result is higher module efficiency (up to 22.86% in the GXQ TS series) and a significantly lower annual degradation rate than conventional PERC cells. For the system owner, this translates into more power generated from the same roof area and more stable energy production throughout the entire operational lifetime. ### Are Axitec AXIbiperfect GXQ TS panels suitable for installation on a pitched roof with limited available space? Modules in the AXIbiperfect GXQ TS series measure 2384 × 1303 × 35 mm and deliver up to 710 Wp at an efficiency of up to 22.86%. This allows more power to be harvested from a constrained roof area compared to standard panels. The glass-glass construction and 35 mm aluminum frame are compatible with typical tile and metal-sheet mounting systems. However, the large module format may require verification of the structural load capacity of older roof trusses prior to installation. ### How much additional energy does the bifacial construction of the AXIbiperfect GXQ TS panels generate? Thanks to their bifacial design, AXIbiperfect GXQ TS modules can produce up to 30% more energy than equivalent monofacial modules, depending on the ground surface reflectivity (albedo). The best results are achieved on high-albedo surfaces such as white gravel, light-colored concrete, or snow. On a typical pitched roof, the actual bifacial gain is lower but still measurable, and the module itself operates identically to a conventional panel. ### Do AXIbiperfect GXQ TS modules perform well during heat waves and high ambient temperatures? Yes. The temperature coefficient of the AXIbiperfect GXQ TS series is just -0.31%/°C, placing it among the best performers on the market. This means that for every 25°C rise in module temperature above the reference temperature, the module loses only approximately 7.75% of its nominal power output, compared to the typical 9–10% loss seen in PERC panels. In practice, during hot summer conditions, a GXQ TS-based installation will produce noticeably more electricity than systems based on older technology. ### Is Axitec AXIbiperfect GXQ TS manufactured by a German company, and is the brand reliable? Axitec Energy GmbH & Co. KG is a company headquartered in Germany with extensive experience in the photovoltaic module market. The manufacturer does not currently appear on the Bloomberg NEF Tier 1 lists; however, it offers one of the longest product and power warranties available — 30 years — and the AXIbiperfect GXQ TS series is actively available and supported. Before purchasing, it is advisable to verify the local availability of warranty service support in your region. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DB_132zlg_biperfect_GXQ_TS_MiA_EN-e616cc67f6ea.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -50 W, lighter, +2.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.6 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +2.4 pp | | [Axitec AC-690TGB/132TS](https://comparepv.com/panel/axitec-ac-690tgb-132ts) | 690 W | Very close match | | [Axitec AC-700TGB/132TS](https://comparepv.com/panel/axitec-ac-700tgb-132ts) | 700 W | Very close match | | [Axitec AC-705TGB/132TS](https://comparepv.com/panel/axitec-ac-705tgb-132ts) | 705 W | +10 W, +0.3 pp | | [Axitec AC-710TGB/132TS](https://comparepv.com/panel/axitec-ac-710tgb-132ts) | 710 W | +15 W, +0.5 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +110 W, cooler, +2.7 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +105 W, cooler, +2.5 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +100 W, cooler, +2.4 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +95 W, cooler, +2.2 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +65 W, cooler, +2.1 pp | --- Source: https://comparepv.com/panel/axitec-ac-695tgb-132ts 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.
