Middle of its segment, modest efficiency
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.

Signals from the data
Commercial.
Tight roof space, hot climates and roofs where every square metre has to count.
Bottom 20% of the HJT 450-500 W segment, against a median of 22.77%.
Bottom 22% of the HJT 450-500 W segment, against a median of -0.240.
Bottom 24% of the HJT 450-500 W segment, against a median of 227.7.
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.
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.
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.
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.
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.
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.
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.
- Efficiency of 22.1% is 0.7pp below the HJT 450-500W median (22.8%)
- Power density of 222.8 W/m² is 4.9 W/m² below HJT 450-500W median (227.7 W/m²) - needs more roof space
- Temperature coefficient of -0.26%/°C is 0.02pp worse than HJT 450-500W median (-0.24%/°C) - higher losses in summer heat
- Bifaciality factor of 95% can add 5-14% extra yield with reflective mounting surface
- In the top 43% for efficiency among all HJT panels
