The temperature coefficient of -0.30%/°C for Pmax is approximately 0.04–0.06 percentage points better than typical PERC modules (-0.34 to -0.36%/°C), which, in the Polish climate during the summer (30°C above STC), results in a real increase of approximately 1.2–1.8% in power output on hot days. - **30-year power guarantee – 87.4%** - The manufacturer guarantees a minimum power retention of 87.4% after 30 years of operation under linear power warranty – the same level of retention as Jinko Solar Tiger Neo 66HL4M-BDV (30 years / 87.4%), which places the series among the global leaders in the segment. - **Power up to 630W – standard for high-end devices** - The maximum power output of 630 Wp matches that of direct competitors (Canadian Solar TOPBiHiKu6 630 Wp, Jinko Tiger Neo 66HL4M-BDV 630 Wp), reducing the number of modules required in the installation and lowering BOS (Balance of System) costs – which is particularly important in large-scale PV farm projects. - **PID immunity built into N-type devices** - The N-type architecture in TOPCon technology exhibits structural resistance to PID (Potential Induced Degradation) without the need for additional anti-degradation coatings, which stabilizes annual yields in string configurations at high system voltages (up to 1500 V DC). ## Cons - **Performance lower than the segment leaders** - The maximum efficiency of the AU-156MH series is 22.54% – 0.76% less than Canadian Solar TOPBiHiKu6 (23.3%) and Jinko Tiger Neo 66HL4M-BDV (23.32%) at the same maximum power of 630 Wp. For this same power output, the series requires approximately 3–4% more roof space than the modules of its main competitors. - **Lack of bifaciality** - AU-156MH is a monofacial module (is\_bifacial: false), while all comparable modules in the 630 Wp segment – including Canadian Solar TOPBiHiKu6 Anti-Dust and Jinko Tiger Neo 66HL4M-BDV – offer bifacial technology. The potential energy gain from the rear side of the module typically ranges from 5–30%, depending on the albedo of the surface and the mounting angle. - **Austa Energy does not currently meet the Tier-1 requirements of the BNEF (Benchmark Natural Energy Financial) rating system.** - The producer (Austa Energy) is not listed on the BNEF Tier 1 Q1 2026 list as a standalone, bankable entity. This could pose a barrier to project financing of solar farms by independent commercial banks, which typically require confirmation of Tier-1 bankability from the module supplier. ## About this series AU-156MH series photovoltaic panels utilize advanced **monocrystalline cells in Half-cut technology**, which translates into significantly higher energy efficiency even in demanding lighting conditions. Thanks to the use of large-format silicon wafers, this design effectively minimizes power losses on internal connections, offering stable operation for decades. A key differentiator is **excellent resistance to the PID phenomenon** and degradation caused by external factors, which guarantees security and predictability of yields for investors. This series solves the problem of limited installation space, generating more energy per square meter compared to older types of modules. The innovative frame design ensures **high resistance to snow and wind loads**, making them an ideal choice for the Polish climate. AU-156MH panels are dedicated to both extensive home installations and commercial farms, where a quick return on investment matters. They are distinguished from the competition by an optimal balance between high efficiency and system costs, as well as a **reduced power temperature coefficient**, allowing for effective operation on hot days. This is a solid solution for investors focusing on proven PERC technology in a modern edition. ## Notable figures - Efficiency of 21.8% matches the \*\*PERC 600-650W\*\* median - At 218.2 W/m² power density, this panel generates 4.4 W/m² more per unit area than \*\*PERC 600-650W\*\* median (213.8 W/m²) - Temperature coefficient of -0.30%/°C vs median -0.34%/°C means ~2% less power loss at 65°C - 30.7 kg weight - 3.3 kg lighter than \*\*PERC 600-650W\*\* median (34.0 kg), reducing installation effort - Ranked #7000 out of 14005 panels for efficiency in the database ## Questions ### What is the warranty for AUSTA ENERGY AU-156MH series solar panels? The AU-156MH series is covered by a 12-year product warranty from the manufacturer, as well as a 30-year linear warranty for output power. After 30 years of operation, the module should maintain at least 87.4% of its nominal output power. This is an acceptable level for the mid-range segment, although it is important to ensure that the local distributor respects the warranty terms, rather than solely relying on the manufacturer based abroad. ### What is the TOPCon technology used in the AU-156MH series, and is it a better option than PERC? TOPCon (Tunnel Oxide Passivated Contact) is a technology for N-type solar cells of the latest generation. Compared to popular PERC cells, it offers higher energy conversion efficiency (above 22% for the AU-156MH series), lower temperature coefficient, and slower degradation over time. This translates to better annual yields and higher power output per square meter of roof area, particularly noticeable in installations with limited surface area. ### Is the AUSTA ENERGY AU-156MH series still available for purchase? No, the AU-156MH series has been discontinued and is no longer offered by the manufacturer as an active product. Some distributors may still have existing stock, but it is essential to verify availability and confirm that the manufacturer's warranty will be honored before making a purchase. It may be worthwhile to consider newer, currently manufactured series with similar specifications. ### How does a 630 Wp AU-156MH panel perform in the summer, under very high temperatures? The AU-156MH series has a power temperature coefficient of -0.30%/°C, which is one of the key advantages of TOPCon technology. In practice, this means that when the surface temperature of the module reaches 45°C (typical Polish summer), the panel loses approximately 7.5% of its power relative to the nominal STC value. This is a more favorable result than in older PERC technologies, making August heat less of a factor in energy generation. ### What is the weight of the AU-156MH panel, and will my roof be able to support an installation consisting of such modules? The AU-156MH module weighs approximately 30.7 kg with dimensions of 2465 x 1134 x 30 mm. These are large and heavy modules belonging to the high-power 630 W category. Before installation, it is essential to have a qualified installer or structural engineer assess the load-bearing capacity of the roof structure, especially in older buildings with wooden trusses. A properly designed installation does not pose a risk to typical roofs in good condition. ### Is AUSTA ENERGY a Tier 1 manufacturer, and does this status affect the quality of the AU-156MH panels? AUSTA ENERGY is not listed as a Tier 1 manufacturer according to the BloombergNEF classification, which means a lower level of financial recognition in the institutional market. This does not automatically imply poor product quality, but when purchasing panels from the discontinued AU-156MH series from stock, it is particularly important to carefully check the warranty terms and conditions in Poland, as well as to ensure that the distributor can guarantee support for the entire declared warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/img-id9qd12n4n-0cc0f569a128.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +40 W, cooler, +3.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -50 W, lighter, +3.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +3.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +2.8 pp | | [Longi Solar LR8-66HVD-660M](https://comparepv.com/panel/longi-lr8-66hvd-660m) | 660 W | +50 W, cooler, +2.6 pp | | [AUSTA ENERGY AU590-39V-MH](https://comparepv.com/panel/austa-energy-au590-39v-mh) | 590 W | -20 W, -0.7 pp | | [AUSTA ENERGY AU595-39V-MH](https://comparepv.com/panel/austa-energy-au595-39v-mh) | 595 W | -15 W, -0.5 pp | | [AUSTA ENERGY AU600-39V-MH](https://comparepv.com/panel/austa-energy-au600-39v-mh) | 600 W | -10 W, -0.4 pp | | [AUSTA ENERGY AU605-39V-MH](https://comparepv.com/panel/austa-energy-au605-39v-mh) | 605 W | Very close match | | [AUSTA ENERGY AU615-39V-MH](https://comparepv.com/panel/austa-energy-au615-39v-mh) | 615 W | Very close match | | [AUSTA ENERGY AU620-39V-MH](https://comparepv.com/panel/austa-energy-au620-39v-mh) | 620 W | +10 W, +0.4 pp | | [AUSTA ENERGY AU625-39V-MH](https://comparepv.com/panel/austa-energy-au625-39v-mh) | 625 W | +15 W, +0.5 pp | | [AUSTA ENERGY AU630-39V-MH](https://comparepv.com/panel/austa-energy-au630-39v-mh) | 630 W | +20 W, +0.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +70 W, cooler, +3.4 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +65 W, cooler, +3.2 pp | --- Source: https://comparepv.com/panel/austa-energy-au610-39v-mh 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.
