Solid all-round for its segment
The MY Solar P2 photovoltaic panel series is an advanced solution based on Half-Cut cell technology, which effectively minimizes energy losses resulting from partial shading and internal resistance. Thanks to the use of modern architecture, these modules offer significantly higher efficiency compared to standard designs, which translates into a faster return on investment for owners of single-family homes and commercial buildings. A key distinguishing feature of the P2 series is its exceptional resistance to potential-induced degradation (PID), which guarantees stable power production for decades, even in demanding weather conditions. These panels perform excellently on cloudy days and at low light angles, ensuring maximum energy yield in low-light conditions. The robust frame construction allows for safe installation in locations exposed to heavy snow loads, solving the problem of installation durability in the Polish climate. For investors who value aesthetics, the P2 series provides an elegant All Black finish, which blends perfectly with modern architecture. Choosing this series means opting for proven reliability, which distinguishes it from the competition through lower susceptibility to micro-cracks and a better temperature coefficient, making it the optimal basis for an efficient and aesthetic micro-installation.
Ranking
Signals from the data
Residential, shaded-installations and cold-climate.
The half-cut cell architecture lowers resistive losses and mitigates partial-shading effects, and the smaller silicon fragments are less prone to microcracks than full-size cells used in older module designs.
The top-end efficiency (17.1%) matches the comparable JA Solar P2 series (170 Wp, 17.1%) and exceeds competing ASM170M and AU Optronics ASM Mono, both at 16%.
The stated 25-year linear power warranty is in line with the segment standard and supports a stable long-term energy yield forecast for the installation.
The aesthetic All Black finish combined with a reinforced frame rated for high snow loads makes the series a good fit for residential installations in the Polish climate.
MY Solar is not classified as a Tier 1 (bankable) manufacturer under BNEF criteria, which in practice can make bank financing or insurance harder to secure for larger commercial projects compared to the same power-class JA Solar P2 series.
The weakest variant reaches only 15.1% efficiency, roughly 0.9 pp below comparable ASM170M and AU Optronics ASM Mono modules (16%) — actual efficiency thus depends heavily on which variant in the series is selected.
The 12-year product warranty is shorter than the 15–25 year standard now offered by leading PERC/N-type panel manufacturers, which can reduce the installation's resale value over the long term.
PERC cells lag behind the increasingly common N-type technologies (TOPCon, HJT) in LID/LeTID degradation resistance and temperature coefficient, which can translate into slightly lower energy yield during high summer temperatures.
- Efficiency of 16.1% is 3.3pp below the PERC 0-400W median (19.4%)
- 161.4 W/m² power density is 33.0 W/m² below PERC 0-400W median (194.4 W/m²) - requires larger installation area
- Temperature coefficient of -0.37%/°C matches the PERC 0-400W median
- At 11.2 kg, this panel is 9.3 kg lighter than PERC 0-400W median (20.5 kg) - easier handling during installation
- #13624 for efficiency, #13081 for temperature performance out of 14005 panels
