Whether you're preparing for grid outages, reducing peak-time utility costs, or maximizing your solar investment, a battery backup system is a smart move. At TAG Roofing & Solar, we install cutting-edge storage solutions including Enphase IQ Battery, and FranklinWH. We guide you through rebates, incentives, and pairing options that fit your energy profile.


For homeowners adding backup batteries to their solar system, we also install smart switches that detect outages instantly and shift power to essential loads—so your lights, fridge, and Wi-Fi stay on without lifting a finger.


Most residential systems are installed in 1–2 days and include permitting, wall-mounting, conduit, software setup, and emergency backup configuration.

Battery Storage FAQs

  • Can I add a battery to my existing solar system?

    Yes. We retrofit batteries to existing solar systems or install them stand-alone.

  • How much backup will I have during a power outage?

    Most residential batteries can power essentials (fridge, lights, Wi-Fi) for 12–24 hours.

  • Is battery storage eligible for tax credits?

    Yes. Batteries paired with solar typically qualify for a 30% federal tax credit. SGIP rebates may cover up to 40% more.

  • What’s the difference between backup and self-consumption?

    Backup provides emergency power; self-consumption offsets grid use during expensive utility rate times.

With TAG Roofing & Solar, battery backup means peace of mind—delivered professionally, configured precisely, and installed to code.

Our home is 32 years old and needed a new roof. Karl was great and easy to work with through the estimation/quote process. The office was easy to work with for payments and scheduling. Anthony and his team were fun to work with while delivering on everything they said they'd do. Anthony kept the project running on schedule, worked around rainy days, and was a great resource for us to ensure our home was safe. The new roof looks excellent, new wood work around the roof turned out great, overall very happy.
