Energy storage systems
Battery storage that keeps the essentials running
A battery stores solar or grid energy so your lights, refrigerator, heat and Wi-Fi can keep running when the grid goes down — and can make your solar more useful every day. Quest Solar is a Tesla Powerwall Certified Installer.

Why battery storage (ess) with Quest
Backup power
Choose the circuits that matter — essentials only or most of the home — and the battery takes over automatically during an outage.
More value from solar
Store daytime solar for the evening instead of exporting it, which can matter where export credits are lower than retail rates.
Utility programs
Some utilities and states offer storage incentives or pay for battery participation during peak events. Programs vary by state and change often.
Business resilience
For commercial sites, storage can protect critical loads and help manage demand charges.
How the process works
Goals and load review
We list what you need powered during an outage and for how long, and review your electrical panel.
System design
We size battery capacity and inverter output, decide between whole-home and essential-load backup, and plan the equipment location.
Permits and utility approval
Electrical permits, fire-code placement rules and utility interconnection are handled for you.
Installation and commissioning
We install, configure backup settings and the monitoring app, and walk you through how it works.
Properties this suits
- Homes with existing or new solar
- Homes without solar that want backup power
- Homes with medical equipment, sump pumps or home offices that need power continuity
- Small businesses, nonprofits and multifamily common areas with critical loads

Where we install
Frequently asked questions
How long will a battery power my home?
It depends on battery capacity, which circuits are backed up and how much energy you use during the outage. We model this for your home during design.
Can I add a battery to my existing solar system?
In many cases, yes. Compatibility depends on your existing inverter and electrical panel; we check both before recommending a system.
Are there incentives for batteries?
Some states and utilities offer storage incentives — for example, Connecticut's Energy Storage Solutions program. Terms change frequently, so we confirm the current offer for your utility during your consultation instead of quoting a number here.
Where does the battery go?
Usually in a garage, basement or on an exterior wall, following the manufacturer's instructions and local fire-code placement rules.
Is Quest Solar certified to install Tesla Powerwall?
Yes. Quest Solar is a Tesla Powerwall Certified Installer serving homes and buildings across our New York, New Jersey, Connecticut and eastern Pennsylvania service territory. Every system still requires a site assessment, electrical review and final design.
