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.

Signals from the data

5 positive · 4 caution
Best for

Residential, commercial and shaded-installations.

What owners get
Partial shading resistance

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.

No busbars - fewer micro-cracks and hot-spots

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.

Better performance at high temperatures

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 aesthetics suited to modern architecture

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.

Higher efficiency than some peer series

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.

Trade-offs
Shorter warranty than typical for shingled tech

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.

Manufacturer not tier-1 bankable

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).

Efficiency below the typical shingled-tech range

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.

Low unit module power

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.

Notes from the database

Common questions

6 answered
How does the shingle cell technology in MY Solar P3 panels work and why is it worth choosing?
Shingle technology stacks PERC cells directly on top of one another, eliminating traditional metal busbars. This gives the MY Solar P3 a larger active light-harvesting area than a conventional module of the same dimensions, resulting in higher power density. This is especially valuable when roof space is limited. Removing busbars also eliminates mechanical stress points that are the primary cause of micro-cracks in cells.
How does the MY Solar P3 series handle partial shading on a roof?
The P3 series uses internal parallel circuits between shingle cell segments, so shading one section of the module does not block current flow through the rest. In real-world installations on roofs with chimneys, dormers, or nearby trees, power losses are significantly lower than with conventional modules using series-connected cells.
What warranty comes with MY Solar P3 panels and what does it cover?
MY Solar provides a 12-year product warranty on the P3 series covering material and manufacturing defects. A separate 25-year linear power output warranty guarantees that the panels maintain a specified percentage of their nominal power over that period. The rated power for this series reaches up to 300 Wp. Before purchasing, confirm that the warranty is enforceable through a local authorized distributor.
Do MY Solar P3 Full Black panels suit modern roofs and how do they compare visually to standard modules?
The Full Black variants of the P3 series feature uniformly black cells, frame, and backsheet, allowing the panel to blend seamlessly into the roof surface without disrupting the look of modern architecture. This is a clear aesthetic advantage over standard modules with visible silver busbars. The darker frame does not compromise performance, though it may slightly increase operating temperature on very hot days.
Are MY Solar P3 panels resistant to hot spots and micro-cracks?
Yes, this is one of the key advantages of the shingle technology used in the P3 series. Eliminating busbars removes the mechanical stress concentration points that are the main source of micro-cracks in conventional modules. The internal parallel circuits also significantly reduce hot-spot formation, which are localized overheating events that can permanently damage cells and, in extreme cases, pose a fire risk.
What type of installation is the MY Solar P3 series best suited for, and will it work on a small residential roof?
The P3 series, rated up to 300 Wp, is designed for both residential prosumer installations on pitched and flat roofs and smaller commercial projects. The high energy density of shingle technology means more kilowatts can be generated from a limited roof area compared to standard PERC modules, making the P3 a strong choice for homes with a small or partially shaded roof section.
