JinkoSolar Tiger Neo modules suited to high temperature environments

By JinkoSolar

The inherent property of silicon generally means the higher the temperature, the lower the efficiency. With monocrystalline PERC cells having a temperature coefficient of -0.4% -0.5%/ ℃, N-type TOPCon cells and modules differentiate themselves by having one below -0.3 %/ ℃. This means that, whereas a PERC panel loses half of one percent of its power with each degree of temperature increase, an N-type TOPCon panel will lose only 0.3% or less.

Taking JinkoSolar’s new Tiger Neo 610W (STC) module as an example, it has a better than average power loss of only -0.3% / ℃ compared with the PERC equivalent of -0.4%/ ℃.  Assuming maximum output power of 610W in a module installed in desert conditions with temperatures reaching 50 degrees Celsius, power loss can be calculated as follows:

50 degrees C – 25 degrees C = 25 degrees C.

Therefore, panel power loss difference = 25 ° C x (0.4%-0.3%) x 610 W = 15.25W.

In conclusion, the temperature coefficient is a parameter used to calculate power loss, usually ranging between -0.3% and 0.5% / ° C, meaning that a temperature increase of 10° C will result in a module power drop of between 3% and 5%. This formula clearly indicates that TOPCon technology, with a 0.3%/°C coefficient, will limit any such power drop to less than 1/3 of the power loss of a PERC module.

This is an important factor for investors in PV power plants, since it significantly affects profitability, making TOPCon modules a preferred choice for large installations and, in the case of ultra large installations operating at high temperatures, a necessary choice.
