Middle of its segment, weak in heat
MY Solar M6 series photovoltaic panels use advanced monocrystalline PERC cell technology, which translates into high solar energy conversion efficiency even in less favorable weather conditions. Thanks to the use of a half-cut design, meaning cells cut in half, these modules show significantly lower internal losses and higher resistance to point shading, which is crucial for the stable operation of installations on the roofs of residential buildings. This series is distinguished by its precision-engineered frame and solid sealing, which guarantees exceptional mechanical strength against snow and wind loads, ensuring safety of use for decades. MY Solar M6 is a solution dedicated to investors seeking an optimal balance between modern technology and a quick return on investment. Compared to competing solutions, this series manages heat dissipation better, which directly affects the minimized temperature coefficient and longer lifespan of the entire system. It is an ideal choice for both home micro-installations and larger commercial systems, where the priority remains maximizing yields from the available roof area while maintaining full operational reliability in the Polish climate. The use of proven M6 silicon wafer formats ensures full compatibility with most mounting systems available on the market.
Ranking
Signals from the data
Residential, commercial, shaded-installations and cold-climate.
Hot climates, tight roof space and roofs where every square metre has to count.
Bottom 1% of the PERC 400-450 W segment, against a median of -0.350. Ranked 13,659th in the whole database.
Bottom 4% of the PERC 400-450 W segment, against a median of 20.60%. Ranked 12,801st in the whole database.
Bottom 5% of the PERC 400-450 W segment, against a median of 206.2. Ranked 12,769th in the whole database.
The M6 series spans 11 variants from 195 Wp to 455 Wp, allowing installers to match a module to anything from small residential microinstallations to larger commercial systems within a single product line.
Half-cut cells reduce resistive losses and improve shade tolerance compared to full-size PERC cells, resulting in more stable energy yield in partially shaded rooftop environments.
The manufacturer offers an industry-standard 25-year power warranty, giving investors predictable production output over the typical amortization horizon of a PV installation.
The use of the widely adopted M6 silicon wafer format ensures dimensional compatibility with most mounting systems on the market, simplifying design and speeding up installation.
Precise frame manufacturing and sealing deliver strong mechanical resistance to snow and wind loads, which is significant for the typical winter roof loads seen in the Polish climate.
The maximum efficiency of 20.6% trails comparable 455 Wp modules from peers such as LEDVANCE M435~455N54LB-SF-F7 (22.77%) and Sunlike SKT420~455M10-108D6 (22.8%), meaning lower energy yield for the same roof area.
MY Solar does not hold BloombergNEF Tier 1 bankable status, which can make it harder to secure bank or leasing financing for larger commercial projects that require such confirmation.
Comparable peer series exceed 22.5% efficiency using newer cell technologies, while PERC is approaching its theoretical efficiency ceiling (~24%), limiting further performance gains for this series relative to the competition.
- Module efficiency of 19.5% is 1.1pp below average for PERC 400-450W panels (median: 20.6%)
- Power density of 194.6 W/m² is 11.6 W/m² below PERC 400-450W median (206.2 W/m²) - needs more roof space
- -0.39%/°C temperature coefficient - 0.04pp worse than PERC 400-450W median (-0.35%/°C), expect higher hot weather losses
- At 25.6 kg (3.6 kg above PERC 400-450W median of 22.0 kg), requires checking roof load capacity
- Ranked #12801 out of 14129 panels for efficiency in the database
