This depends on your operational hours. If you can operate some or most of your high-power equipment during the hours that solar produces energy (between 8 am and 5 pm), you can save some or a lot on the demand charges. If you have a business that has a fairly early start, you may not be able to lower your demand through your solar production. But the good news is, when you install a solar power system, all the utility companies offer electricity rates that are specific to renewable energies, and these rates tend to charge much less for each kW, which lowers the cost of demand charges significantly.
Vaha Energy also offers battery-related solutions to shave a building’s demand, which further reduce the demand related costs.
