This translates to a difference of approximately 0.5–1 m² in the required surface area for a typical 10 kWp prosumer installation. ## Cons - **The series has been discontinued (2023)** - The ODA-120MHD series was available from 2021 to 2023 and is now discontinued. This means limited availability of new modules for expanding the installation, difficulty in accessing certified service technicians, and a lack of ongoing technical support from the manufacturer – all of which pose a significant risk for 25-30-year investments. - **Manufacturer not on the Tier-1 BNEF list** - AUSTA ENERGY is not listed on Bloomberg NEF's Tier-1 bankability list, which makes it difficult to secure project financing and may be disqualifying in commercial tenders or solar farm bids that require confirmation of bankability from insurers. - **A brief overview of the market for the producer** - The company, founded in 2015 (approximately 11 years of market presence), with its headquarters in India, has a significantly shorter operational history compared to its competitors (Jinko Solar – since 2006, REC Group – since 1996). This reduces the likelihood of accurately assessing its long-term ability to honor a 30-year power output warranty. - **Performance is lower than the segment leaders by approximately 1.1 percentage points.** - The maximum efficiency of 22.62% is 1.07 percentage points lower than Jinko Eagle G7B and Powitt Solar (23.69%). For installations with limited roof space (e.g., 40 m²), this difference translates to a real reduction of approximately 400-500 Wp per square meter in peak power compared to the most efficient available alternatives. - **15-year product warranty – below premium** - The warranty for the product is 15 years, while the REC Alpha Pro M Series offers a 25-year product warranty (frame + backsheet). For the premium N-type bifacial segment, 15 years is below market expectations and could influence an investor's decision when comparing the total cost of ownership (TCO). ## About this series The ODA-120MHD photovoltaic panel series introduces a new level of quality to prosumer and commercial installations, utilizing advanced **N-type TOPCon cell** technology. Thanks to the **bifacial double glass** design, these modules not only generate energy from direct solar radiation but also effectively utilize reflected light reaching the back of the panel. This solves the problem of limited installation space, allowing for higher power generation from the same roof or ground area. The use of **half-cut technology** minimizes energy losses resulting from shading and reduces the risk of hot-spots, which directly translates into the fire safety of the entire installation. The ODA-120MHD stands out from the competition with its exceptional resistance to potential-induced degradation (PID) and light-induced degradation (LID), guaranteeing stable energy yields for decades. This solution is dedicated to investors seeking maximum **durability in harsh weather conditions**, such as strong winds or snow loads. By choosing this series, the user receives a product that combines an innovative crystalline structure with an aesthetic finish, making the panels blend perfectly with modern architecture while providing the **lowest levelized cost of energy (LCOE)**. ## Notable figures - Module efficiency of 22.3% is 0.5pp below average for \*\*TOPCon 600-650W\*\* panels (median: 22.8%) - At 222.6 W/m², this panel generates 5.1 W/m² less per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - Weight of 34.5 kg is 1.8 kg above \*\*TOPCon 600-650W\*\* median (32.7 kg) - verify structural support - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### Is the AUSTA ENERGY ODA-120MHD series still available for sale? The ODA-120MHD series has been discontinued and is no longer available for regular sale. If you are looking for similar specifications – N-type TOPCon technology, a bifacial double glass structure, and a power output of around 640 W – it is advisable to inquire with a distributor about currently available replacements from reputable Tier 1 manufacturers that offer comparable performance and full warranty support. ### What warranty period does the ODA-120MHD panel from the AUSTA ENERGY series cover? The ODA-120MHD series was covered by a 15-year product warranty (for material and workmanship defects) and a 30-year linear performance warranty. After 30 years of operation, the manufacturer guaranteed the maintenance of a specified minimum percentage of the nominal power output. It is important to note that AUSTA ENERGY is not listed on Tier 1 manufacturer lists, which in practice may make it more difficult to enforce warranty claims after the series is discontinued. ### What does the N-type TOPCon technology mean in the ODA-120MHD panels, and is it worth paying extra for? N-type TOPCon solar cells exhibit lower annual degradation rates compared to traditional P-type PERC cells, better temperature coefficients (less power loss in hot weather), and higher resistance to PID and LID effects. For a 640 W panel, this translates to a significantly higher amount of energy produced over the entire lifespan. The premium is particularly justified in installations designed for long-term return on investment. ### How does bifacial double-glass technology work in the ODA-120MHD series, and when is this design truly cost-effective? A bifacial double-glass panel features an active rear surface covered with tempered glass instead of a film, allowing it to collect light reflected from the ground, roof, or other surfaces. The actual energy gain ranges from 5–25%, depending on the albedo (reflectivity) of the surface beneath the panel – the highest gain is achieved with a light, sandy surface, a white roof membrane, or snow. The bifacial effect is minimal on a dark, bituminous roof, so it is important to assess the mounting conditions before making a decision. ### Is the ODA-120MHD panel with a power output of 640W suitable for a residential rooftop installation? Panel 640W in the ODA-120MHD series is a large-format module – typically in the 2278x1134 mm class – primarily intended for commercial and ground-mounted installations. While installation on the roof of a single-family home is technically possible, the large dimensions and weight (approximately 35 kg) require a reinforced supporting structure and make it difficult for the installation team. Most installers opt for smaller formats of 400-430W, which are better suited to standard roof pitches. ### Will the ODA-120MHD panels withstand strong winds and heavy snow loads? The double-glass construction (two panes of tempered glass instead of glass with a rear foil) provides high mechanical strength and resistance to loads. Typical panels of this class are certified for wind loads up to 2400 Pa and snow loads up to 5400 Pa, which corresponds to extreme atmospheric conditions in Poland. However, it is advisable to verify the specific values in the technical specifications of the particular product before installation, as parameters may vary between different power variants within the series. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/c882456894dbc297ffd3362c56943f49-1b62526fa4ba.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +50 W, lighter, +2.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +45 W, lighter, +2.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +40 W, lighter, +2.5 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +40 W, lighter, +2.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.5 pp | | [AUSTA ENERGY ODA610-30V-MHD](https://comparepv.com/panel/austa-energy-oda610-30v-mhd) | 610 W | -20 W, -0.7 pp | | [AUSTA ENERGY ODA615-30V-MHD](https://comparepv.com/panel/austa-energy-oda615-30v-mhd) | 615 W | -15 W, -0.5 pp | | [AUSTA ENERGY ODA620-30V-MHD](https://comparepv.com/panel/austa-energy-oda620-30v-mhd) | 620 W | -10 W, -0.4 pp | | [AUSTA ENERGY ODA625-30V-MHD](https://comparepv.com/panel/austa-energy-oda625-30v-mhd) | 625 W | Very close match | | [AUSTA ENERGY ODA635-30V-MHD](https://comparepv.com/panel/austa-energy-oda635-30v-mhd) | 635 W | Very close match | | [AUSTA ENERGY ODA640-30V-MHD](https://comparepv.com/panel/austa-energy-oda640-30v-mhd) | 640 W | +10 W, +0.4 pp | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | Hotter, lighter, +1.8 pp | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | Hotter, lighter, +1.6 pp | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +40 W, cooler, +1.4 pp | --- Source: https://comparepv.com/panel/austa-energy-oda630-30v-mhd 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.
