Middle of its segment, heavy for its output
The MY Solar ALTRA N-Type TOPCon Bifacial (Dual-glass framed, N144) series are modules designed for maximum energy yield in situations where every percentage counts - especially for ground-mounted and PV farm installations. A key advantage is the combination of N-Type TOPCon cells with a dual-sided (bifacial) design, allowing the panel to not only generate power from the front but also to effectively utilize reflected light from the ground (albedo). This translates to higher yields on the same surface area and improved project profitability.
The use of double-glass enhances resistance to environmental conditions and reduces the risk of degradation over the long term - a crucial factor for investments spanning decades. The half-cut and multi-busbar technology helps minimize losses and improve stability under less-than-ideal sunlight conditions. An additional advantage is salt and ammonia resistance, making installation easier in coastal, agricultural, and high-humidity areas. This is a choice for investors, EPC companies, and firms that want to extract maximum energy from the same BoS infrastructure.
Ranking
Signals from the data
Utility-scale, commercial and shaded-installations.
Weight-limited structures, roofs where every square metre has to count and tight roof space.
Bottom 16% of the TOPCon 550-600 W segment, against a median of 53.8.
Bottom 20% of the TOPCon 550-600 W segment, against a median of 224.4.
Bottom 22% of the TOPCon 550-600 W segment, against a median of 22.44%.
Up to 22.65% efficiency in top-bin variants matches the best peer comparables (Hanersun Hitouch 5N, Q-SUN Qrystal N8) - the upper limit currently available for N144 TOPCon technology on the market.
Combining N-Type cells (lower LID/LeTID degradation than PERC) with a bifacial dual-glass construction meaningfully boosts energy yield on ground-mount installations by capturing albedo light reflected from the ground.
A full 25-year product warranty paired with a 30-year power warranty matches premium-segment standards - many tier-2 manufacturers offer only 10-15 years of product warranty alongside a comparable power warranty.
Certified corrosion resistance enables installation in coastal, agricultural, and high-humidity zones without additional protective measures or special module variants.
Half-cut cells with multiple busbars reduce resistive losses and improve performance stability under partial shading, which matters on large ground-mount farms with uneven irradiance.
MY Solar does not appear on BloombergNEF's Tier-1 manufacturer list, which can complicate non-recourse bank financing for large-scale farm projects - unlike peer comparables such as Risen, which do hold Tier-1 status.
Efficiency ranges from 21.9% to 22.65% depending on the variant (565-585W), while comparable competitor series (Hanersun, Q-SUN) achieve 22.65% across nearly their entire power range - the lower-end ALTRA variants clearly trail the segment leaders.
Released in 2022, the series has roughly 4 years of market presence, limiting the availability of long-term field-performance data to support the claimed 30-year power warranty compared to manufacturers with a longer track record.
- Efficiency of 21.9% is 0.5pp below the TOPCon 550-600W median (22.4%)
- 218.7 W/m² power density is 5.7 W/m² below TOPCon 550-600W median (224.4 W/m²) - requires larger installation area
- At -0.29%/°C, hot weather performance is typical for TOPCon 550-600W panels
- Bifaciality factor of 85% can add 4-13% extra yield with reflective mounting surface
- #6847 for efficiency, #2220 for temperature performance out of 14129 panels

Datasheet charts
Measured curves published by MY Solar in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 565 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
Model: bifaciality × albedo × 0.6 view factor. A first-order estimate, not a yield simulation.
