The HJT solar cell was first introduced in the early 1980s by Sanyo and later by Panasonic of Japan. The product cost of the HJT solar cells has reduced significantly in the last decade.
​
This technology is becoming one of the top choices of manufacturers for making solar panels with increased efficiencies.

​REC is solar’s most trusted brand that produces quality solar panels. This Norwegian company was founded in 1996 and so far, has manufactured 40 million solar panels, 11 gigawatts produced, and is enjoyed by over 17 million people.

We see solar panels having solar cells from 36 cells to 144 cells.
Each silicon cell, cut into square pieces, joined, and encapsulated in an aluminium frame called a solar module.

Today in this post, I will discuss the basic difference between the 60 cells vs 72 cells.
