This translates into a real increase in energy yield for the same roof area. - **N-type TOPCon cell technology** - N-type TOPCon cells exhibit lower LID/LeTID degradation than older PERC solutions and a favorable temperature coefficient of -0.30%/°C, improving output on hot days compared to P-type modules. - **Half-cut cells with SMBB/MBB** - Half-cut cell construction reduces resistive losses and hot-spot risk under partial shading, while SMBB/MBB busbar technology improves current collection in low-irradiance conditions, increasing production predictability. - **30-year / 87.4% power warranty** - The manufacturer guarantees at least 87.4% of nominal power retained after 30 years (following 99% after the first year), matching standards used by leading TOPCon manufacturers and supporting a longer investment payback period. - **Bifacial dual-glass variants available** - Double-sided variants with dual glass allow for additional energy gain from reflected light on bright roof surfaces, carports, and ground-mount structures. ## Cons - **Limited brand recognition** - Unlike the peer comparables JA Solar, GCL, and Risen - established tier-1 manufacturers with a long track record in global markets - Ocean Solar (founded in 2012) has significantly lower brand recognition, which can affect project financing ease and resale valuation of the installation. - **12-year product warranty below market trend** - The 12-year product warranty is shorter than the 15-year standard that many tier-1 manufacturers (e.g., JA Solar) now offer for TOPCon modules in this power range, which can matter when comparing total lifecycle service risk cost. ## About this series The Ocean Solar AOX-72M10HC series comprises half-cut modules based on M10 cells, designed for high efficiency and stable performance in rooftop and larger commercial installations. The use of **N-type TOPCon technology** helps minimize losses due to degradation and maintain good performance even in harsher temperature conditions. The **half-cut cell** design improves performance under partial shading and reduces the risk of hot-spot formation, leading to greater safety and predictable energy production. Furthermore, **SMBB/MBB** solutions enhance current collection and improve performance under weaker sunlight conditions. Versions with **bifacial and double-glass** construction can generate additional power from reflected light, which will be appreciated by investors on bright roofs, balconies, and ground-mounted structures. This series is ideal for those who want to combine high efficiency with durability and lower maintenance costs over the lifespan of the system. ## Notable figures - Efficiency of 23.8% is 1.0pp above the \*\*TOPCon 600-650W\*\* median (22.8%) - At 238.1 W/m² power density, this panel generates 10.4 W/m² more per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 600-650W\*\* panels - Weight of 28.0 kg (4.7 kg below \*\*TOPCon 600-650W\*\* median of 32.7 kg) allows easier transport and roof mounting - Ranked #433 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the Ocean Solar AOX-72M10HC series come with? The AOX-72M10HC series includes a 12-year product warranty covering material defects and workmanship, along with a 30-year linear power warranty. The manufacturer guarantees that modules will retain at least 87.4% of their nominal power output after 30 years of operation. N-type TOPCon technology inherently degrades more slowly than legacy PERC cells, meaning real-world end-of-warranty performance is typically better than the guaranteed minimum. ### How heavy is the Ocean Solar AOX-72M10HC panel and can it be installed on a standard pitched roof? The AOX-72M10HC module weighs approximately 31.5 kg and measures 2278×1134×30 mm — standard dimensions for a 72-cell 600 W+ panel. On a typical pitched roof with rafter spacing of 60–90 cm, mounting on standard aluminum rails presents no issues. You should verify that the roof structure can handle a load of roughly 15–20 kg/m², which is within the capacity of most residential and light commercial roofs. ### What is N-type TOPCon technology and why choose it in the AOX-72M10HC series over cheaper PERC modules? TOPCon (Tunnel Oxide Passivated Contact) uses an N-type silicon wafer with a thin tunnel oxide passivation layer that reduces electron recombination. In practical terms, this translates to higher efficiency (up to 23.8% in this series), a lower temperature coefficient of approximately -0.30%/°C versus roughly -0.35%/°C for PERC, and slower long-term degradation. For the end customer, this means more kilowatt-hours generated from the same roof area across the full system lifetime. ### Do the Ocean Solar AOX-72M10HC panels perform well in overcast conditions and on cloudy days? Yes. The combination of half-cut M10 cells and SMBB/MBB busbar technology improves current collection efficiency and low-irradiance response compared to standard modules. Half-cut cells reduce internal string resistance, enhancing performance under diffuse light conditions. Installers and homeowners in Central and Northern Europe can expect more consistent energy yields throughout the year, not only during peak summer sunshine hours. ### How do the half-cut cells in the AOX-72M10HC series protect the system against shading and hot-spots? In a conventional module, shading one cell can throttle an entire string. Half-cut cells split the panel into two electrically independent halves: shading the bottom section — for example from a chimney or dormer — does not block output from the top half. The smaller individual cell area also reduces operating currents, which significantly limits the formation of hot-spots. The result is lower risk of long-term damage and more predictable energy production on rooftops with obstructions. ### What types of systems are the Ocean Solar AOX-72M10HC modules best suited for — residential or commercial? With output up to 615 Wp, AOX-72M10HC modules are primarily designed for larger installations: flat commercial rooftops, industrial warehouses, carports, and ground-mount arrays. Their high per-module power reduces the total module count and Balance of System (BoS) costs. They also work well on large residential pitched roofs. For very small prosumer systems of 3–5 kWp, the large physical dimensions may be a limiting factor on narrow roof sections. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/mono-580w-615w-monofacial-b5d84e714025.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +35 W, cooler, +1.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +30 W, cooler, +1.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +25 W, cooler, +1.0 pp | | [Longi Solar LR8-66HVD-665M](https://comparepv.com/panel/longi-lr8-66hvd-665m) | 665 W | +50 W, heavier, +0.8 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (665W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-665w-class) | 665 W | +50 W, heavier, +0.8 pp | | [Huayao HY665-B144DSS](https://comparepv.com/panel/huayao-hy665-b144dss) | 665 W | +50 W, cooler, +0.8 pp | | [Sunpro Power SPDG665-BC132R12](https://comparepv.com/panel/sunpro-spdg665-bc132r12) | 665 W | +50 W, heavier, +0.8 pp | | [Ocean Solar AOX-72M10HC 580W](https://comparepv.com/panel/ocean-solar-aox-72m10hc-580w) | 580 W | -35 W, -1.4 pp | | [Ocean Solar AOX-72M10HC 585W](https://comparepv.com/panel/ocean-solar-aox-72m10hc-585w) | 585 W | -30 W, -1.2 pp | | [Ocean Solar AOX-72M10HC 590W](https://comparepv.com/panel/ocean-solar-aox-72m10hc-590w) | 590 W | -25 W, -1.0 pp | | [Ocean Solar AOX-72M10HC 595W](https://comparepv.com/panel/ocean-solar-aox-72m10hc-595w) | 595 W | -20 W, -0.8 pp | | [Ocean Solar AOX-72M10HC 600W](https://comparepv.com/panel/ocean-solar-aox-72m10hc-600w) | 600 W | -15 W, -0.6 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +20 W, cooler, +0.8 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | Cooler, heavier, +0.6 pp | --- Source: https://comparepv.com/panel/ocean-solar-aox-72m10hc-615w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
