Trending in solar panels: PERC, new cell designs diversifying competitive market

By Kelly Pickerel While 60-cell panels are still dominant, it appears more powerful 72-cell designs are being used, according to Solar Media Ltd. This can mostly be attributed to more 72-cell panels being used in utility-scale solar—the largest solar market—as these projects are looking for the highest output.

Some of the most cost-efficient ways to reach even higher outputs with larger solar panels are through PERC designs or increasing the number of busbars. Both can contribute to 72-cell panels producing outputs near 350 W.
More busbars means there are more paths for electrons to pass down, leading to increases in
