This video explores the technical advantages of Heterojunction Technology (HJT) solar panels, featuring an in-depth explanation of how REC Group has made HJT commercially viable at competitive costs.
Key insights:
HJT sandwiches an n-type mono crystalline silicon cell between amorphous silicon layers, broadening the light spectrum the cell responds to and converting infrared light into current rather than heat, which keeps panels cooler and improves performance.
This superior thermal coefficient results in higher annual energy yield compared to TOPCon and PERC alternatives.
HJT panels achieve a 95% bifaciality rate, outperforming competing architectures; annual degradation of just 0.25% allows REC to warranty 92% of nameplate output after 25 years.
And an advanced wire interconnect system embedded in a transparent conductive oxide film replaces traditional bus bars, adding structural protection and making thinner, more flexible cells far more resistant to microcracks from hail or physical loads.
