Solar + Storage Retrofit
Quick answer
Already have solar? Add a battery and stop exporting cheap and buying expensive. Retrofits typically $10,000–$25,000, and the battery can earn state storage incentives on its own.Typical installed cost: $10,000–$25,000
Solar without storage sells your surplus at wholesale and buys it back at retail, and shuts down entirely in an outage. A battery retrofit fixes both: your panels charge the battery, the battery covers evening peaks and blackouts. We assess your existing inverter and design AC- or DC-coupled to fit.
About Solar + Storage Retrofit
Millions of homes installed solar under net-metering deals that no longer exist for new customers, and millions more watch their panels go dark in every outage. A battery retrofit upgrades the economics and the resilience in one project, without touching what's on the roof.
The technical fork is coupling: AC-coupled batteries (Powerwall) sit behind any existing inverter and are the standard retrofit path; DC-coupled makes sense when your inverter is due for replacement anyway. We assess your system's age, inverter, and rate plan, then design to the numbers.
What changes the day the battery goes live
- Evening peak hours run on stored solar instead of retail grid power
- Outages: panels + battery form their own grid, lights stay on
- Export minimized where net metering pays wholesale
- The app finally shows the whole picture: solar, storage, home, grid

Grid-tied inverters must disconnect when the grid fails (anti-islanding, protecting lineworkers). A battery with backup capability creates its own grid, keeping panels producing while the utility is down.
Almost always, AC-coupled batteries (like Powerwall) pair with any existing system without touching your panels. We verify compatibility during the free assessment.
The federal credit is gone as of January 1, 2026, but state and utility storage programs generally treat the battery on its own installed cost, regardless of when the solar went in.
Yes, it's common. We verify the existing system's health first, document it, and add storage, you gain a live warranty relationship on the whole energy system going forward.
