Middle of its segment, weak in heat
MY Solar M3 series photovoltaic panels focus on maximizing energy yields through the use of Half-Cut cell technology, which effectively reduces resistance losses and improves module performance in partial shading conditions. This design addresses the problem of sudden performance drops in densely built-up areas, making this series an excellent choice for prosumer installations mounted on the roofs of single-family houses. The use of a reinforced anodized aluminum frame guarantees high resistance to snow and wind loads, which is crucial in the variable Polish climate. What sets them apart from the competition is primarily the low temperature power coefficient, thanks to which the modules lose significantly less energy during intense sunlight on hot days. The innovative cell surface structure allows for better capturing of diffused light, which extends the actual operating time of the system on cloudy days. The M3 series combines high efficiency with modern aesthetics, offering a durable and safe solution. It is an option for demanding investors who expect a quick return on investment while maintaining the highest standards of resistance to the PID degradation phenomenon and other negative external factors. These modules constitute a solid foundation for a modern micro-installation, guaranteeing predictable electricity production for many years.

Residential and shaded-installations.
Hot climates.
Bottom 16% of the PERC 350-400 W segment, against a median of -0.350.
Half-cut cells reduce resistive losses and improve module performance under partial shading, which is relevant for dense single-family rooftop layouts and non-standard mounting angles.
30 variants within a single series allow matching a module to small balcony installations as well as larger pitched or commercial roofs, without switching suppliers during design.
The frame construction increases resistance to snow and wind loads, which matters for system design in Poland's variable climate with periodic heavy snowfall.
Modules lose less power as cell temperature rises on hot days, translating into higher real-world energy yield during summer months compared to older-generation standard PERC panels.
Maximum efficiency of 20.45% (PERC technology) is clearly below N-type TOPCon peer comparables at the same 520 Wp max power - Jinko Tiger Neo III reaches 24.06%, DAH Solar 23%, and Silfab Commercial NTC 21.9%. This means a larger installed area is required for comparable generated power.
MY Solar is not listed as a BloombergNEF Tier 1 bankable manufacturer, which can complicate project financing where banks and insurers require this status as a lending condition.
The M3 series carries a 10-12 year product warranty, while the same manufacturer's own N-type/HJT lines (e.g. MySolar GOLD HJT) offer 30-year product and power warranties as standard. This positions M3 as an entry-level, older-generation offering within the manufacturer's own portfolio.
- At 19.7% efficiency, this panel is on par with typical PERC 0-400W modules
- Power density of 197.0 W/m² matches the PERC 0-400W median
- Temperature coefficient of -0.37%/°C matches the PERC 0-400W median
- Weight of 22.3 kg is 1.8 kg above PERC 0-400W median (20.5 kg) - verify structural support
- In the top 89% for efficiency among all PERC panels
