Space saver, short guarantee
The Axitec AXIbipremium XXL HC MT series is an advanced solution for demanding investors who prioritize maximum energy efficiency. The key distinguishing feature of these modules is bifacial technology, which enables the generation of additional energy from reflected radiation, which, combined with the large XXL format, allows for record-breaking yields from every square meter of surface area. Thanks to the use of an innovative Half-Cut design, these panels effectively eliminate the problem of performance drops in partial shading conditions, which is crucial for the stability of system operation in Polish weather conditions. The use of the Multi-Busbar system shortens the electron flow path and strengthens the cells' resistance to mechanical loads, which drastically extends the lifespan of the entire installation. This series is primarily dedicated to large-scale farms and industrial facilities where the lowest levelized cost of energy matters. Compared to the competition, this product stands out for its exceptional resistance to degradation and precise matching of components, which guarantees trouble-free operation for many years. By choosing AXIbipremium XXL HC MT, you gain investment certainty based on solid German engineering, which realistically translates into a faster return on investment and higher profits from electricity production.

Top 20% of the PERC 550-600 W segment, against a median of 212.9.
Bottom 24% of the PERC 550-600 W segment, against a median of 27 yrs.
N-type TOPCon cells deliver a Pmax temperature coefficient of approximately -0.30%/°C and an annual degradation rate of ~0.4%/year, compared to ~0.35%/°C and ~0.55%/year for PERC technology. In the Polish climate — characterized by cool mornings and variable irradiance — this difference translates into a measurable increase in annual energy yield of several percentage points over the full system lifetime.
The bifacial module design harvests additional energy from albedo-reflected irradiance on the rear surface. With typical ground albedo values for light gravel or snow cover, the real-world annual yield gain is 5–15%, directly reducing the LCOE of ground-mount and carport installations without requiring additional modules.
A peak efficiency of 21.48% positions this series above ET Solar Elite PLUS (21.4%) and Boviet VEGA (21.3%), and at virtual parity with JA Solar DEEP BLUE 3.0 (21.5%). In the XXL format (144 cells, Pmax 555 Wp), this translates into a smaller roof or land footprint for the same installed capacity, lowering balance-of-system (BoS) costs per installed MW.
Splitting cells in half reduces internal I²R resistive losses by ~75% compared to full cells, and partial shading on one half of the module does not disable the entire string. The multi-busbar (MBB) configuration shortens current path lengths and improves cell resistance to microcracks — a critical advantage for XXL-format modules exposed to snow and wind loads in Polish conditions.
The 15-year product warranty exceeds that of certain competitors in this segment — for example, JA Solar DEEP BLUE 3.0 offers a 12-year product warranty per ENF/SolarReviews. The 25-year linear power output guarantee provides cash flow predictability for utility-scale PV projects with a typical financing horizon of 20–25 years.
Axitec does not appear on the BloombergNEF Bankable Module Makers list (tier_1_bankable: false). For non-recourse-financed utility-scale PV projects, lenders and financial institutions routinely require modules from BNEF Tier-1 manufacturers. This creates potential financing barriers or the need for additional credit enhancements on projects above 1 MWp, where competitors such as JA Solar — a Tier-1 manufacturer — hold a structural advantage.
The AXIbipremium XXL HC MT series has been on the market since 2021 without a documented product refresh. Between 2024 and 2026, leading TOPCon manufacturers such as Jinko Tiger Neo and LONGi Hi-MO 9 have introduced modules achieving 22–23% efficiency and Pmax above 600 Wp at comparable price points. When planning long-term utility-scale farms, this series should be benchmarked against the latest market offerings before a final procurement decision is made.
- At 21.5% efficiency, this panel is on par with typical PERC 550-600W modules
- At 214.8 W/m² power density, roof space requirements are typical for PERC 550-600W panels
- At -0.35%/°C, hot weather performance is typical for PERC 550-600W panels
- 28.5 kg weight - 2.3 kg lighter than PERC 550-600W median (30.8 kg), reducing installation effort
- Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof
