When we analyze Mysolar/Mamibot solar panels we see every technical advantage:
Saving a big amount of money on BOS:up to 7%
A much better low-light output that contributes a 1% more power gain
Less Micro-crack risks as the processing temperature of HJT cells is lower than 250℃
Super high power output, up to 710W in lab and 700W in mass production with dimension 2384*1303*35mm, it’s Mysolar GOLD series.
But technology is one side of the coin, second is warranty and Company abilities. And in this aspect, Mysolar (Mamibot brand) is a leader in the PV market:
Summarizing MYSOLAR first position, the key and strong advantage of are an all-in-one solution that combines the best HJT solar panels with a wide range of solar construction like trackers and bifacial dedicated products.

Is a new technology aimed to achieve higher energy conversion efficiency by adding a dielectric passivization layer on the rear of the cell.
The structure of a PERC solar cell from front to rear:
Screen-printed Silver paste front contact;
Anti-Reflective Coating (ARC);
Silicon wafers that form the P-N junction;
Local Aluminum Back Surface Field (Al-BSF);
Dielectric passivation layer;
SiNx Capping Layer;
and
Screen-printed Aluminum paste layer.
Cells combined the advantages of c-si and thin film technologies, with excellent light absorption and passivation effects, super efficiency and power output. It increases conversion efficiency and power output to the highest level. The natural bifacial symmetrical structure of HJT cells can effectively improve the power generation capacity on the module’s backside.

Solar Module is connected to the size of module and silicon(or CIGS and Perovskite) production technology. For the utility-scale project in most cases, bigger power means better LCOE a BOS costs. But for e.g. big solar investments on roofs have to have special needs like weight and then smaller panels will be dedicated.
Warranty and Insurance of Warranty is a most crucial aspect. Product Warranty for Producer. Of course higher and longer mean better. The lowest warranty is 10-12 Years(Risen and Jinergy). Medium warranty is between 15-20 (Jolywood) years and the best top class modules are 20-30(Akcome or Mysolar) years.
Bifaciality the HJT cell is a kind of N-type cell with a naturally symmetrical bifacial structure. It’s born with high bifacility up to 95% without any extra processing. General Perc cells have up to 70% baficiality only. This means, with the same size as the bifacial module, Mysolar’s HJT bifacial module can gain up to 6% higher power output than PERC bifacial modules. The closer to the equator, the more yield the panels will get.
Linear Power Loss/output warranty. This warranty shows how fast PV modules will be degraded and how much power will produce solar panels after 25-30 years. 25 years have mostly modules low class or without glass-glass cover. 30 years have good quality solar panels. Another important issue at this point is how fast the module will lose power. Best modules in this aspect have even more than 90% after 30 years(Akcome or Mysolar). Good modules have between 85-90% after 30 years and worst are below 85%.
The temperature Coefficient is strictly connected to the technology with which the solar panel is made of. Best in class is HJT solar panels with temperature coefficients below %/ ℃, mostly 0,25 %/℃. It’s crucial everywhere where the temperature of module and environment increase the high level, causing energy production rapidly slow down.
Surface layer of HJT cell is TCO without insulating the layer which does not cause accumulation of charges, prevent the potential-induced degradation, and avoid PID for the modules. As the N-type wafer does not have B-O bond, it results in a zero LID effect and guarantees the module’s durability and yield. HJT cells are also applicable to Shingled Technology.

HJT + perovskite tandem solar cells are still under development, but they have the potential to be commercially viable in the near future. In 2023, several companies announced that they were developing HJT + perovskite tandem solar cells for commercial use.
Tandem solar cells are a type of solar cell that combines two or more different photovoltaic materials in a single device. This allows tandem cells to capture a wider range of the solar spectrum and generate more electricity than single-junction cells.
