Introducing SolarCity DemandLogic
Demand management and backup power made easy

Lock in low demand charges and save for years to come


Smart Battery

Automatic demand reduction

You don’t need to change your business operations or load shift to lower demand. SolarCity DemandLogic uses intelligent algorithms in conjunction with your solar power system to automatically reduce your demand during peak periods.

Start saving right away

DemandLogic reduces your demand charges from day one. And because demand charges tend to rise, your savings increase over time.


Backup Power

Be prepared for power outages

Keep high-priority critical systems running even during power failures. The optional DemandLogic backup system can be your safeguard against an aging and increasingly unstable utility grid. Your solar array recharges the battery system during longer outages.

DemandLogic is backed by a 10-year guarantee that promises that you’ll get the demand reduction that we predict each month or we’ll pay you the difference. The system also carries a full warranty. We cover all repairs and insurance.

“Utilities have altered their rate structures such that demand charges are rising faster than overall energy rates, and businesses are bearing the bulk of those increases. Our storage system gives businesses immediate savings and protection against escalating demand charges, and can also provide optional grid-independent backup power in case of outages.”
