While commercial and residential solar are similar, there are a few key differences between them. With residential, billing is based off of usages and some fixed charges. However, commercial rate plans are based off of usage as well as demand charges. Demand charges cannot always be fully offset with solar installations, and many times a battery storage will need to be considered for peak-demand shaving. One of our experts would be glad to explain these charges in more detail.
In addition, tax incentives are dramatically different for commercial solar installations. While the current 26% investment tax credit (ITC) is the same, Federal bonus depreciation, state depreciation and other tax credits will impact the commercial installation return on investment.
