Thanks to the bifacial glass-glass construction, this series excels at overcoming challenges such as potential-induced degradation and the negative impact of atmospheric factors. **Increased low-light efficiency** ensures that the system produces energy effectively even on cloudy days, which is crucial for the Polish latitude. The use of a **Half-Cut structure** minimizes internal losses and the risk of hot spots, directly translating to a longer lifespan for the entire system. This solution is primarily dedicated to investors looking to maximize profits from limited roof or ground space. What sets them apart from the competition is their exceptional **resistance to extreme mechanical loads** and a low temperature coefficient, guaranteeing stable operation on hot days. By choosing the ODA-120MHD, the user receives a product that optimizes self-consumption and shortens the return on investment time, combining innovation with solid workmanship. It is the ideal choice for modern households and demanding business installations where durability and predictability of energy yields for decades are priorities. ## Notable figures - At 21.1% efficiency, this panel is 0.8pp below the \*\*database\*\* median of 21.8% - At 210.8 W/m², this panel generates 7.3 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - Temperature coefficient of -0.35%/°C is 0.05pp worse than \*\*database\*\* median (-0.30%/°C) - higher losses in summer heat - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface - Ranked #9586 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the PolyCrown Solar Tech ODA-120MHD series come with? PolyCrown Solar Tech provides a 15-year product warranty and a 30-year power output warranty for the ODA-120MHD series. The power warranty guarantees that the panels will maintain a specified minimum output over three decades, following the manufacturer's defined degradation curve. A 30-year power warranty is especially important when financing a solar installation, as it serves as a bankable basis for long-term yield projections. ### What is N-type TOPCon technology and why does the ODA-120MHD series use it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type silicon cell technology that adds a thin tunnel oxide passivation layer to minimize carrier recombination at the rear contact. Compared to PERC cells, TOPCon achieves higher conversion efficiency, a lower temperature coefficient of Pmax (typically around -0.30%/°C), and effectively zero LID/LeTID degradation risk. The ODA-120MHD series leverages these advantages for superior hot-weather performance and a longer usable lifespan over the full 30-year warranty period. ### Do the bifacial ODA-120MHD panels make sense for a standard pitched residential roof? Bifacial panels deliver the greatest energy gain in ground-mounted systems or flat-roof installations where the rear glass captures irradiance reflected off a bright surface below. On a steep pitched roof with dark roofing, bifacial gain typically falls to just 5-10%. That said, the ODA-120MHD's dual glass construction independently provides superior moisture resistance and PID immunity, extending module lifetime compared to conventional glass-backsheet modules regardless of the bifacial contribution. ### How do ODA-120MHD panels perform in low-light conditions and overcast weather? The N-type TOPCon cells in the ODA-120MHD series offer a broader spectral response and a higher short-circuit current under diffuse irradiance compared to standard PERC modules. This translates to efficient energy generation even on the cloudy autumn and winter days common across Poland. The half-cut cell architecture further reduces partial shading losses and lowers internal series resistance, improving low-light output across the entire array. ### How many 460 Wp ODA-120MHD panels are needed to build a 10 kWp system? At a peak power of 460 Wp, approximately 22 ODA-120MHD panels are required to reach 10 kWp. That is 2-3 fewer panels than with common 400-420 Wp modules, which means less roof area consumed or lower racking and labor costs for an equivalent system output — a significant advantage when available roof space is limited. ### Can ODA-120MHD panels handle heavy snow loads and hard frost in the Polish climate? The ODA-120MHD series is engineered for exceptional mechanical load resistance, and its dual glass construction meets or exceeds IEC snow load certification thresholds. The glass-glass laminate eliminates moisture ingress and backsheet delamination risks in sub-zero temperatures. Additionally, the low temperature coefficient of N-type TOPCon cells means output remains stable — or even improves relative to STC — on cold, clear winter days when irradiance levels are high. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ccd2c2e5e5f2fd0c40a1d79ec5c56867-2c07d08413e6.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +3.6 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +3.4 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +3.4 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | Cooler, lighter, +3.4 pp | | [PolyCrown Solar Tech ODA440-30V-MHD](https://comparepv.com/panel/polycrown-solar-tech-oda440-30v-mhd) | 440 W | -15 W, -0.7 pp | | [PolyCrown Solar Tech ODA445-30V-MHD](https://comparepv.com/panel/polycrown-solar-tech-oda445-30v-mhd) | 445 W | -10 W, -0.5 pp | | [PolyCrown Solar Tech ODA450-30V-MHD](https://comparepv.com/panel/polycrown-solar-tech-oda450-30v-mhd) | 450 W | -0.2 pp | | [PolyCrown Solar Tech NS-450MH-120](https://comparepv.com/panel/polycrown-solar-tech-ns-450mh-120) | 450 W | Cooler, lighter, -5 yr warranty | | [PolyCrown Solar Tech ODA460-30V-MHD](https://comparepv.com/panel/polycrown-solar-tech-oda460-30v-mhd) | 460 W | +0.2 pp | | [PolyCrown Solar Tech NS-460MH-120](https://comparepv.com/panel/polycrown-solar-tech-ns-460mh-120) | 460 W | Cooler, lighter, -5 yr warranty | | [PolyCrown Solar Tech NS-470MH-120](https://comparepv.com/panel/polycrown-solar-tech-ns-470mh-120) | 470 W | Cooler, lighter, -5 yr warranty | | [PolyCrown Solar Tech NS-480MH-120](https://comparepv.com/panel/polycrown-solar-tech-ns-480mh-120) | 480 W | Cooler, lighter, +1.1 pp | | [PolyCrown Solar Tech NS-485MH-120](https://comparepv.com/panel/polycrown-solar-tech-ns-485mh-120) | 485 W | Cooler, lighter, +1.3 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +105 W, cooler, +3.7 pp | --- Source: https://comparepv.com/panel/polycrown-solar-tech-oda455-30v-mhd Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
