While commercial solar does an excellent job offsetting typical use, businesses that accrue demand charges would still have to pay their utility the high-costs of having enough energy available to meet spikes in demand. Energy storage systems can solve this problem through a process called Peak Shaving. By using reserve batteries to meet high-demand, instead of relying on your utility for quick bursts in demand for electricity, a commercial solar system paired with energy storage can shave its own peaks without incurring those pesky demand charges.
