When to choose 60 cell vs. 72 cell panels

Jun.19.2020 239

If the only difference between 60- and 72-cell solar panels is their size, how do you choose one over the other?

The ultimate decider is panel value, measured in cost-per-watt.

Divide the price of the panel by the rated panel output (typically 250W-375W per panel). This will give you a baseline to compare panel value, regardless of size.

Our advice is to go for the best cost-per-watt option that fits the space where you will install your system.

Here’s an example. If your mounting space is 35’ wide and 10’ tall, you can only fit a row of 10 panels. You can install more power by using 72-cell panels because you have enough space to accommodate the taller panel size.
