Retrofit storage
Solar + storage retrofit, add a battery to solar you already own.
Already have solar? Add a battery and stop exporting cheap power while buying it back expensive. The battery can also earn state storage incentives on its own.
What’s included
- Battery retrofit for most existing solar inverters
- Stops low-value grid export in favor of self-use
- Standalone state storage incentives, separate from your original solar credit
$10,000–$25,000
Typical cost
Most existing inverters
Compatibility
Up to 10 yrs

Retrofit storage
A solar system without storage leaves value on the table.
If your utility pays little for exported solar power but charges full price to buy it back at night, every kilowatt-hour you export instead of store is a missed savings opportunity. A battery retrofit closes that gap.
We start by confirming your existing inverter's compatibility with today's leading battery brands, since not every older system integrates cleanly.
- Inverter compatibility check before any commitment
- Stop low-value grid export in favor of self-consumption
- Add outage backup to a solar system that previously had none
- Battery-specific incentives separate from your original solar credit
Retrofit storage
The retrofit is planned around your existing system, not a rebuild.
In most cases, the existing panels, racking, and much of the electrical infrastructure stay exactly as they are. The project scope is focused on the battery, any required inverter or gateway hardware, and the wiring to tie it into your existing setup.
Permitting, utility interconnection updates, and incentive paperwork are handled as part of the retrofit.
- Minimal disruption to existing panels and racking
- Battery and gateway hardware sized to your system
- Updated utility interconnection paperwork
- Incentive filing for the battery addition
Common questions
Can any solar system be retrofitted with a battery?
Most modern inverters support a battery retrofit, though compatibility varies by brand and age. We confirm this during the free assessment before recommending a specific battery.
Are there separate incentives for a battery retrofit?
Yes, in many states the battery can qualify for its own storage incentives, separate from whatever credit applied to your original solar installation.
Will the retrofit require rewiring my whole solar system?
Usually not. Most retrofits add the battery and any required gateway hardware to the existing system without touching the panels or racking.
