Light for its output, no clear weak spot
The MY Solar P3 series consists of advanced photovoltaic modules based on innovative shingled technology, which redefines efficiency standards in challenging lighting conditions. By eliminating traditional busbars and overlapping the cells directly, these panels offer a significantly larger active area, which translates into direct maximization of yields from every square meter of roof surface. They solve the key problem of power drops during partial shading, offering unique shading resistance thanks to the use of parallel circuits inside the module. This solution is dedicated primarily to demanding residential and commercial installations, where not only high power matters, but also impeccable aesthetics - Full Black variants blend perfectly with modern architecture. What distinguishes the P3 from the competition is its increased mechanical strength and radically reduced risk of micro-cracks and dangerous hot-spots, ensuring stable and safe operation of the entire system for decades. By choosing this series, the investor receives maximum energy density while maintaining high component durability, making these modules one of the most cost-effective options in the high-performance technology segment currently available on the Polish market.
Ranking
Signals from the data
Residential, commercial and shaded-installations.
Top 12% of the PERC 250-300 W segment, against a median of 66.5.
Top 15% of the PERC 250-300 W segment, against a median of 172.1.
Top 17% of the PERC 250-300 W segment, against a median of 17.21%.
The parallel internal circuit architecture typical of shingled-cell technology means shading on one segment does not disable the entire module, unlike classic busbar panels with a single series-connected cell string.
The use of electrically conductive adhesive (ECA) instead of copper busbars reduces resistive losses and the risk of micro-cracks and dangerous hot-spots, contributing to greater long-term operational stability of the module.
Shingled modules typically show a more favorable power temperature coefficient (around -0.34%/°C vs. -0.40%/°C for standard busbar PERC panels), meaning lower energy losses during hot weather.
Full Black variants with no visible busbars or gaps between cells give roofs a uniform black appearance, a key selling point for residential installations on prominent roof planes.
The maximum efficiency of 18.01% exceeds reference series DMEGC Greenhouse (11.61%) and Solitek SOLID Agro Frameless (14.88%), making P3 a competitive option against some products available on the Polish market.
The product warranty is 12 years and the power warranty is 25 years, while shingled-cell panels (including other series from the same manufacturer) commonly offer a 30/30-year warranty on the market. This may signal lower manufacturer confidence in the long-term durability of this specific series.
MY Solar does not appear on the tier-1 bankable manufacturer list, which can complicate project financing and risk insurance compared to brands recognized as bankable (e.g., JA Solar).
The maximum efficiency of 18.01% falls below the typical 18.5-21.3% range quoted for mature shingled modules, undermining the 'maximum energy density' marketing claim used in the series description.
The 160-300 Wp power range is notably lower than modern standard panels (400-600+ Wp), meaning larger installations require more modules, MC4 connectors, and mounting hardware for the same installed capacity, raising BoS costs and installation time.
- At 18.0% efficiency, this panel is 1.4pp below the PERC 0-400W median of 19.4%
- 180.0 W/m² power density is 14.4 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
- 16.9 kg weight - 3.6 kg lighter than PERC 0-400W median (20.5 kg), reducing installation effort
- In the top 94% for efficiency among all PERC panels
