Middle of its segment, heavy for its output
PolyCrown Solar Tech ODA-120MHD panels are advanced modules based on N-type TOPCon cell technology, setting new efficiency standards in the Polish photovoltaic sector. 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.
Ranking
Signals from the data
Residential, commercial, shaded-installations and hot-climate.
Weight-limited structures and hot climates.
Bottom 12% of the 360-560 W band, against a median of 52.6.
Bottom 20% of the 360-560 W band, against a median of -0.300.
N-type TOPCon cells in a glass-glass bifacial design reduce LID/LeTID degradation and improve low-light performance, which matters given Poland's high share of overcast days.
Splitting cells into halves lowers resistive losses and hot-spot risk, translating into higher long-term module reliability.
The manufacturer offers a 30-year linear power warranty, exceeding the 25-year linear warranty that remains the market standard for many competing TOPCon series.
The ODA-120MHD series has been on the market since 2021 and remains in active production, indicating a mature manufacturing process and continuity of service and spare-parts availability.
The maximum efficiency of 21.31% is clearly below comparable TOPCon series at the same 460 Wp power class - Phono Solar Draco (23.02%), SunKean SKT440-460M12 (23.02%) and Axitec AXIbiperfect GR WB (22.54%) - meaning more installed area is needed to reach the same system power.
PolyCrown Solar Tech does not appear on BloombergNEF's Tier 1 manufacturer list (Q2 2026), which can complicate obtaining non-recourse financing for larger commercial and utility-scale projects.
The 15-year warranty against material and workmanship defects is shorter than the 25-year product warranty now offered by leading TOPCon manufacturers, despite matching their 30-year power warranty.
- Efficiency of 21.3% is 0.5pp below the database median (21.8%)
- 213.2 W/m² power density is 4.9 W/m² below database median (218.1 W/m²) - requires larger installation area
- Temperature coefficient of -0.35%/°C is 0.05pp worse than database median (-0.30%/°C) - higher losses in summer heat
- Bifaciality factor of 69% can add 3-10% extra yield with reflective mounting surface
- Ranked #8503 out of 14005 panels for efficiency in the database
