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. ## Notable figures - 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 ## Questions ### What warranty comes with the MY Solar M6 series panels? The M6 series includes a 12-year product warranty covering material and manufacturing defects, plus a 25-year linear power output warranty. This means the manufacturer guarantees a defined minimum power yield for a full quarter century. It is a standard warranty scope for mid-range PERC modules and is sufficient for a typical residential prosumer installation. ### What does half-cut PERC technology in the MY Solar M6 mean, and is it worth the price? Half-cut technology splits each PERC cell into two halves, reducing internal resistance and thermal losses. In real-world use this translates to higher output under partial shading - from a chimney or dormer, for example - and better performance on hot days. For any roof with obstructions this is a measurable energy gain, not just a marketing claim. ### Will MY Solar M6 455 Wp panels perform well in Poland's frequently overcast climate? Yes. The monocrystalline PERC cells used in the M6 series maintain solid efficiency under diffuse light, which is typical of Polish autumn and winter conditions. The manufacturer also highlights a minimized temperature coefficient, meaning reduced power losses during summer heat waves. The M6 series is explicitly positioned as a solution adapted to variable weather conditions in Central Europe. ### Are MY Solar M6 modules compatible with standard racking systems available in Poland? Yes. The M6 series is built around the widely adopted M6 silicon wafer format (166 mm), one of the most common cell sizes on the market. This ensures compatibility with the majority of aluminum rail systems and mid-clamps offered by Polish mounting hardware distributors. Always confirm frame dimensions with your racking supplier before ordering. ### How many MY Solar M6 455 Wp panels do I need for a 10 kWp system? At 455 Wp per panel you need 22 modules to reach approximately 10.01 kWp of total installed capacity. Those 22 panels require roughly 40-44 m² of roof area, depending on the racking system and row spacing used. This is a convenient system size for a home of 150-200 m² running a heat pump. ### Is MY Solar a Tier 1 manufacturer, and is it worth buying their panels? MY Solar is not currently listed as a Tier 1 manufacturer by Bloomberg NEF, which means lower bankability recognition compared to top-tier brands. This does not necessarily reflect product quality - the M6 series uses proven PERC cells and offers solid warranties. However, make sure your installer or distributor can handle warranty claims locally in Poland, since after-sales support is critical for less widely known brands. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Product-specification-MYM6144-430-455-a39bb1e33f74.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A480-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a480-mah54mw) | 480 W | +50 W, cooler, +4.6 pp | | [Gokin GK-5-54HG-480M](https://comparepv.com/panel/gokin-gk-5-54hg-480m) | 480 W | +50 W, cooler, +4.6 pp | | [Jinko Solar JKM480N-48QL6-DB-F2-EU](https://comparepv.com/panel/jinko-solar-jkm480n-48ql6-db-f2-eu) | 480 W | +50 W, cooler, +4.6 pp | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +50 W, cooler, +4.6 pp | | [MY Solar MYM6144-435](https://comparepv.com/panel/my-solar-mym6144-435) | 435 W | +0.2 pp | | [MY Solar MYM6144-440](https://comparepv.com/panel/my-solar-mym6144-440) | 440 W | +10 W, +0.5 pp | | [MY Solar MYM6144-445](https://comparepv.com/panel/my-solar-mym6144-445) | 445 W | +15 W, +0.7 pp | | [MY Solar MYM6144-450](https://comparepv.com/panel/my-solar-mym6144-450) | 450 W | +20 W, +0.9 pp | | [MY Solar MYM6144-455](https://comparepv.com/panel/my-solar-mym6144-455) | 455 W | +25 W, +1.1 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +160 W, cooler, +4.4 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +155 W, cooler, +4.2 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +150 W, cooler, +4.0 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +150 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/my-solar-mym6144-430 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
