The MY Solar PLATI N-TYPE HJT BIFACIAL series panels represent a milestone in energy efficiency, utilizing advanced HJT heterojunction cell technology. This solution combines the advantages of crystalline and thin-film silicon, which directly translates into significantly higher module efficiency, especially in challenging lighting conditions. Thanks to the unique bifacial design, these panels actively absorb light reflected from the ground on both sides, allowing for the generation of additional energy compared to traditional monofacial modules. This series effectively eliminates the problem of power drop on hot days, offering an exceptionally low temperature coefficient, which ensures stable operation of the system throughout the summer. It is a product aimed at investors seeking premium solutions that will perform well in both demanding ground-mounted installations and on the roofs of commercial buildings. What sets the PLATI series apart from the competition is the minimized degradation effect and above-average mechanical durability, guaranteeing investment security for years. By choosing this technology, the user receives maximum power density from every square meter, optimizing the costs of the entire mounting structure.

What owners get
HJT N-type cells with low temperature coefficient

Heterojunction (HJT) technology delivers one of the lowest power temperature coefficients on the market (around -0.24%/°C), limiting energy yield losses on hot days compared to conventional PERC or TOPCon cells.

Bifacial design boosts energy yield

Dual-side light absorption typically adds a few to over ten percent extra energy output versus monofacial modules, especially when installed over reflective ground surfaces or on tracker systems.

Matched 30-year product and power warranty

Unlike most manufacturers, who offer 10-15 years of product warranty against 25-30 years of power warranty, the PLATI series provides an identical 30-year term for both, reducing the risk of full module replacement for mechanical or electrical defects once the shorter product warranty expires.

High efficiency versus thin-film technology

Efficiency of 21.2-22.1% significantly exceeds thin-film modules such as First Solar Series 6 Plus (~19% at the same max power of 480 W), translating into a smaller footprint needed to reach the same installed capacity.

Reduced degradation typical of N-type cells

N-type cells do not exhibit the Light Induced Degradation (LID) effect characteristic of older P-type PERC cells, resulting in more stable energy yield during the first years of operation.

Trade-offs
Manufacturer not on the BNEF Tier 1 list

MY Solar is not listed as a Tier 1 bankable manufacturer per the Bloomberg New Energy Finance classification, which may complicate securing bank financing for large commercial and ground-mount projects compared to established Tier-1 brands.

Efficiency below top segment competitors

Maximum efficiency of 22.1% trails comparable modules such as Sunket SKT460~480M10-120D3 (22.24%) and is notably lower than Gamko GKA96N-PRO (24.02%) at the same 480 W max power, making the series less competitive on power density within the premium segment.

Notes from the database
  • Efficiency of 21.9% is 0.9pp below the HJT 450-500W median (22.8%)
  • Power density of 220.4 W/m² is 7.3 W/m² below HJT 450-500W median (227.7 W/m²) - needs more roof space

About the PLATI N-TYPE HJT BIFACIAL series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty comes with the MY Solar PLATI N-TYPE HJT BIFACIAL panels?
The MY Solar PLATI series comes with both a 30-year product warranty and a 30-year power output warranty. This means the manufacturer guarantees a defined performance level for three decades - one of the longest warranty commitments available in the PV module market. It makes the PLATI series a low-risk, long-term investment for residential, commercial, and utility-scale projects alike.
How does HJT cell technology in MY Solar PLATI panels differ from PERC or TOPCon?
HJT cells stack amorphous silicon layers on both sides of a crystalline silicon wafer, enabling superior surface passivation compared to PERC (single rear passivation) or TOPCon (phosphorus diffusion only). The result is a lower temperature coefficient and better low-light efficiency. In real-world conditions this translates to a higher annual energy yield at the same rated wattage - a key advantage for installations with limited roof space or suboptimal orientation.
How much additional energy can I realistically get from the bifacial design of MY Solar PLATI panels?
The bifacial gain - extra output from the rear side absorbing reflected irradiance - typically ranges from 5% to 20%, depending on ground albedo and tilt angle. The highest gains occur on ground-mount systems over light-colored gravel or over white TPO membranes on flat commercial roofs. Under favorable albedo conditions, a 480 Wp PLATI module can deliver effective output comparable to a conventional 500+ Wp monofacial module.
Do MY Solar PLATI HJT panels suffer significant power loss on hot summer days?
No - HJT technology inherently produces a very low temperature coefficient, meaning the module loses less power per degree Celsius above 25°C compared to PERC or TOPCon alternatives. When roof temperatures climb to 60-70°C in summer, a PLATI installation produces noticeably more energy than a same-rated PERC system. This thermal stability is one of the primary reasons the series is recommended for demanding commercial rooftop and ground-mount projects.
Are MY Solar PLATI 480 Wp panels suitable for ground-mount systems and commercial rooftops?
Yes. The PLATI series is engineered for demanding commercial and utility-scale applications. Its above-average mechanical durability means the modules handle the high snow and wind loads typical of large ground-mount arrays. The bifacial design delivers the greatest gains precisely in ground-mount configurations with trackers or on flat roofs where the rear side has unobstructed access to reflected light.
How do MY Solar PLATI N-TYPE HJT panels perform in low-light conditions during fall and winter?
HJT technology delivers some of the best low-irradiance efficiency among commercially available silicon modules. The heterojunction structure converts energy effectively even on overcast days, in morning fog, or at cold winter temperatures. Customers in Northern and Central Europe - where diffuse light dominates for months - consistently report a higher annual energy yield from HJT-based systems compared to monofacial PERC installations of equivalent rated power.
