A question I’ve seen come up time and again is ‘are there commercial solar panels’?
The difference is mostly in the size of the panels. They will be 72-cell rather than 60-cell. The advantage here is that there is a lower cost per watt due to merely adding 2 more rows of cells to the panel. Over larger installations, it also reduces installation times, as there are simply less panels to install to reach the same capacity.
However, they are heavier than 60-cell modules and require sturdier roofs, which is why they are generally not recommended for residential systems.
