Save Even More with Energy Storage
We evaluate your operation's energy use and current utility charges to assess your total potential solar savings.
Design & Installation
We design and build a solar energy system that gives you a lower and more predictable energy cost for years to come.
We give you options to pay for your solar system over time and help you take advantage of available incentives.
We proactively monitor your system’s performance and manage your operations and maintenance.
Your utility bills are mainly composed of two types of electricity charges—one based on energy use and one based on your highest demand in the month. You can think of demand charges as the “high water mark” in your energy usage—you might not use that level of electricity all the time, but at certain times you do, and you don’t want to be gouged for that usage level.
PV systems generate electricity to offset all or most energy charges. But demand charges – incurred when you are importing electricity from the grid—are not completely offset by PV. An ESS installed with a PV system can further increase utility bill savings by reducing demand charges, and hedging against impacts of changes in utility rates and tariffs.
CalCom will evaluate your needs to determine if an ESS will reduce your demand charges, complement savings from solar, and increase your total energy savings.
