The Ocean Solar AOX-144M10RHC panel series utilizes advanced Half-Cut cell technology, which effectively eliminates the problem of performance drops in partial shading conditions and reduces resistive losses. The use of M10 standard silicon wafers translates into optimization of the active surface area, making these modules an ideal choice for investors aiming for maximizing yields per square meter of the installation. Thanks to the innovative multi-busbar design, the panels demonstrate increased resistance to micro-cracks, which significantly extends their trouble-free lifespan. This series is dedicated to large-scale projects and commercial roofs, where the key parameter is minimizing the LCOE index through high energy density. Importantly, this technology offers a much better temperature coefficient, guaranteeing stable operation even during record heatwaves, which distinguishes it from older technological solutions. Choosing the AOX-144M10RHC is an investment in high resistance to light-induced degradation (LID and LeTID), which translates into predictable and high yields throughout the system's lifespan. These panels combine a substantive approach to engineering with mechanical durability, serving as a competitive alternative to the most popular brands on the Polish photovoltaic market.

What owners get
Up to 23% efficiency with N-type TOPCon

N-type TOPCon cells deliver efficiency in the 21.5-23% range, placing the series on par with Phono Solar Draco (23.02%) and SunKean SKT440-460M12 (23.02%) - the leaders in the 430-460 Wp segment.

30-year linear power warranty

The manufacturer offers a 30-year linear power degradation warranty alongside a 12-year product warranty, matching the current premium standard for TOPCon modules and exceeding older 25-year PERC-era warranties.

Half-cut cell and multi-busbar design

Half-cut cells in a multi-busbar layout reduce resistive losses and increase resistance to microcracks and hot-spot effects under partial shading, translating into higher real-world energy yield in suboptimal irradiance conditions.

High power density from M10 wafer

The 430-460 Wp power range on an M10 wafer standard (144 cells) matches the maximum output of the best comparable series (Phono Solar, SunKean, Axitec - all at 460 Wp), important where commercial roof area is limited.

IEC 61215 and IEC 61730 certification

Modules carry full IEC 61215/61730 safety and performance certification, a prerequisite for bank financing and approval for large-scale installations in the EU.

Trade-offs
Manufacturer not on BNEF Tier 1 list

Ocean Solar (founded 2012) does not appear on the BloombergNEF Tier 1 list (Q2 2026), unlike the comparable Phono Solar brand. This may complicate bank financing for large-scale projects, where manufacturer bankability is a key criterion.

No bifacial variant available

The series is monofacial only, while the comparable Axitec AXIbiperfect GR WB offers bifacial technology, enabling additional energy yield from reflected light in ground-mount or high-albedo roof installations.

Common questions

6 answered
What warranty comes with the Ocean Solar AOX-144M10RHC panels?
Ocean Solar provides a 12-year product warranty covering manufacturing defects and workmanship, along with a 30-year linear power output warranty. Over three decades, the manufacturer guarantees the panels retain a specified percentage of their rated power. This warranty package reflects the commercial-grade reliability expected from the AOX-144M10RHC series.
How does the TOPCon technology in the AOX-144M10RHC differ from standard PERC cells?
TOPCon (Tunnel Oxide Passivated Contact) cells incorporate a thin silicon oxide layer that minimizes charge carrier recombination, achieving typical cell efficiencies of 22–24% versus around 20–22% for PERC. Additional benefits include stronger resistance to LID and LeTID degradation and a more favorable temperature coefficient, resulting in higher energy yields across the module's entire service life.
How do the Ocean Solar AOX-144M10RHC panels perform under partial shading from chimneys or trees?
The half-cut cell design splits each cell into two halves, reducing operating current and limiting power loss when part of the panel is shaded. When a shadow covers a section of the module, the remaining portion continues operating with minimal disruption. This makes the AOX-144M10RHC a solid choice for rooftops with chimneys, dormers, or nearby vegetation.
What is the peak power of the AOX-144M10RHC module, and what type of installations is it suited for?
The AOX-144M10RHC series reaches a peak power of 460 Wp. It is primarily designed for large-scale commercial rooftop projects where minimizing LCOE is the main priority. The high energy density enabled by M10 wafers allows fewer panels to be installed, lowering balance-of-system (BoS) costs while maintaining high total system output.
Is the Ocean Solar AOX-144M10RHC a bifacial panel?
No, the AOX-144M10RHC is a monofacial module — it captures solar energy from the front side only and does not generate additional power from light reflected off the ground, as bifacial panels do. It is suitable for both rooftop and ground-mount installations, provided bifacial gain is not included in the energy yield calculations.
What are LID and LeTID degradation, and why does resistance to them matter in the AOX-144M10RHC series?
LID (Light Induced Degradation) and LeTID (Light and elevated Temperature Induced Degradation) are processes that reduce panel output during the first months of operation due to light and heat exposure. Thanks to its TOPCon cell technology, the AOX-144M10RHC series exhibits high resistance to both phenomena, resulting in lower initial power loss and more predictable energy yields throughout the entire 30-year warranty period.
