MY-M2/60 series photovoltaic panels are an advanced solution based on monocrystalline technology, focusing on maximizing energy yields while maintaining compact dimensions. This series stands out for its use of PERC cell technology, which directly translates to higher module efficiency even in low-light conditions, typical of the Polish climate. Thanks to a precise production process, these modules offer exceptional resistance to PID-induced degradation, which guarantees stable system operation for decades. MY-M2/60 is the ideal choice for investors seeking a balance between modern technology and structural durability. Increased mechanical strength against snow and wind loads ensures these panels perform excellently in harsh weather conditions. Unlike standard solutions, this series features a low power temperature coefficient, which minimizes energy losses during hot days. The product is dedicated to both residential rooftop installations and commercial projects where optimizing the mounting area is crucial. By choosing MY-M2/60, you gain the certainty of investing in technology that effectively shortens the payback period of the installation by generating more kilowatt-hours from every square meter of surface.

Strengths
30 year performance warranty

Top 16% of the PERC 300-350 W segment, against a median of 25 yrs.

What owners get
Efficiency matching market leaders

The top-power variant (325 Wp) reaches 19.97% efficiency, nearly matching JA Solar M2 (19.98%) and clearly outperforming Heckert Solar NEMO 2.0 60M BLACK (19.4%) and Solarwatt Vision 60M (19.1%).

30-year linear power warranty

The manufacturer offers a 30-year linear power warranty, longer than the standard 25 years typical for PERC technology, matching terms usually seen with newer N-type/TOPCon cells.

PID degradation resistance

The PERC cells combined with a precise manufacturing process deliver high resistance to potential-induced degradation (PID), supporting more stable energy yield over decades of operation.

Low power temperature coefficient

A low temperature coefficient limits output losses during heat waves, which matters given high module surface temperatures during Polish summer months.

Trade-offs
No BNEF Tier-1 status

MY Solar is absent from the BNEF Tier 1 PV Module Manufacturers list (Q2 2026, 42 manufacturers), unlike peer comparable JA Solar, which holds an AAA bankability rating - this may limit access to project bank financing for commercial installations.

Product warranty limited to 12 years

The 12-year product (workmanship) warranty is shorter than the segment trend shifting toward 25 years, narrowing protection against mechanical failure compared with some premium competitors.

Lower efficiency on base variants

The weakest variant in the series (310 Wp) reaches only 19.05% efficiency, below Heckert Solar NEMO 2.0 (19.4%) and Solarwatt Vision 60M (19.1%) - actual yield therefore depends heavily on the selected power variant within the series.

About the MY-M2/60 series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty does the MY Solar MY-M2/60 series come with?
MY Solar MY-M2/60 panels carry a 12-year product warranty covering material and workmanship defects. In addition, the manufacturer provides a 30-year linear power output warranty - after that period, the module should retain at least 80% of its nominal rated power. This is a solid protection level for PERC modules, ensuring investment stability over decades of operation.
Do MY-M2/60 panels perform well in Poland's frequently overcast climate?
Yes, the MY-M2/60 series is designed for low-irradiance conditions. PERC cell technology enables better absorption of diffuse radiation, so the panels generate more energy on overcast days than standard BSF modules. The low temperature coefficient further reduces losses on hot summer days, resulting in higher annual energy yield under typical Polish weather conditions.
What is PERC technology in the MY-M2/60 and is it actually worth the premium?
PERC (Passivated Emitter and Rear Cell) is a cell technology where the rear surface is coated with a passivation layer that reflects photons back into the silicon. In practice, this delivers roughly 0.5-1% higher efficiency compared to standard BSF cells, along with better low-light performance. For the end user, this means measurably more kilowatt-hours per year without increasing the number of installed panels.
Is the MY-M2/60 a bifacial module?
No, the MY-M2/60 is a monofacial module. Energy is harvested solely from the front glass side. For the vast majority of rooftop installations this is a fully sufficient solution - bifacial modules gain a meaningful advantage mainly in ground-mounted systems with a reflective surface such as gravel or concrete, where rear-side albedo gain is achievable.
What is the rated power of the MY-M2/60 and is it suitable for a residential system?
MY-M2/60 modules deliver a peak power of 325 Wp under STC conditions. This is a typical output for 60-cell PERC modules in the premium segment, well suited for residential rooftop systems in the 5-10 kWp range as well as medium-scale commercial projects. The compact 60-cell format makes it easier to fit smaller roof sections and to install on structures with limited load-bearing capacity.
How does the MY-M2/60 series handle PID, and why does it matter for long-term performance?
The MY-M2/60 series features enhanced resistance to PID (Potential Induced Degradation). PID can reduce module power output by several percent within just a few years, especially in large systems operating at high DC voltages. Built-in PID resistance means the panel maintains stable power output throughout the full 30-year power warranty period, protecting the long-term return on investment.
