Looking into a solar energy lock in and have been hearing a lot about different panel cell amounts. Why are these different cell options both offered? Is there a simple preference here? It's my understanding that they are the same in terms of overall price but would love some guidance here

Solar panels are made up of individual silicon solar cells which are a standard size of approximately 6" x 6". Most panels come with 60 cells, but some have an additional row of cells, which make them slightly larger. A 72 cell solar panel would have a higher power output rating than a 60 cell solar panel made of the same materials, because it has more solar cells on it.

If you're looking at a home solar installation, you probably don't need a 72 cell panel. 60 cell panels are more common for residential rooftop solar installations, while 72 cell panels are more common for ground-mounted, commercial, or utility sized solar installations.

Some roofs have a limited amount of space for panels based on factors such as vents and other items that attach to or project through the roof. My roof did not have room for a 24 panel array made up of 60-cell panels, but I had room for a 17 panel array using the 72-cell panels so that's what I got. It allowed me to keep the panels on the roof and not take up ground space with a ground mounted system and the system provided the same amount of power as would a 24 panel system. I got 9 different contractor quotes for a system to meet my electrical consumption needs and they were all within a few hundred dollars of each other, some using 60-cell panels, some using 72-cell panels.
