  3. Module and solar construction design to perfect fit and maximize the efficiency of both products. 
  4. Flexible payment options for long-term cooperation partnership.
  5. EPC experience and products dedicate especially y utility-scale projects.
  6. Professional PV ROBO Cleaner for utility and C&I customers. 

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.

Solar Panel Review and Important Features

PERC ( Passive Emmitter Rear Contact)

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.

HJT (Heterojunction technology)

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.

How To Choose Power of Solar Panels?

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.

What Solar Modules Have Best Warranty Terms?

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. 

Why Bifacial Solar Panel?

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.

Who have best Linear power output in solar panels?

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%. 

What solar panel has best Temperature Coefficient?

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. 

No PID, No LID and no B-O

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.
