Can I add a battery to my existing solar system?
Yes! Whether we installed your solar or not, we can add a battery to most systems. Our team will inspect your setup and recommend the best storage solution.

Absolutely. Battery storage is eligible for the 30% Federal Solar Tax Credit, even if added after your solar panels were installed.
