Why Add Battery Storage in Tucson?
Tucson's monsoon season brings thunderstorms and occasional power outages. With solar + battery storage, your home stays powered even when the grid goes down. Beyond backup protection, battery storage maximizes your solar investment by letting you use your own solar energy during peak evening hours (3pm-7pm) when TEP rates are highest.
Under TEP's time-of-use rate plans, electricity costs significantly more during peak demand hours — even though your solar panels are producing the most energy during those same hours. Without a battery, you export that cheap solar energy to the grid and buy back expensive evening power. With a battery, you store your daytime solar and use it when rates are highest, dramatically reducing or eliminating peak charges.
Battery Storage Options
Tesla Powerwall 3
The industry leader — 13.5 kWh capacity per unit, integrated inverter, seamless backup transition. Stackable for larger homes. 10-year warranty, app-controlled monitoring. The most popular choice for Tucson homes.
Enphase IQ Battery
Modular AC-coupled batteries (3.36 kWh or 10.08 kWh) that integrate perfectly with Enphase microinverter systems. Great for partial-home backup or incremental expansion over time.

What Size Battery Do You Need?
Battery sizing depends on what you want to power during an outage and your daily energy usage patterns:
- Essentials only (lights, fridge, WiFi, outlets): 1 Powerwall or equivalent (~10-13 kWh) — $8,000-$12,000 installed
- Partial home backup (essentials + some AC): 2 Powerwalls or equivalent (~26 kWh) — $16,000-$24,000 installed
- Whole home backup (everything including AC): 3+ Powerwalls or equivalent — $24,000-$36,000+ installed
All pricing is before the 30% federal tax credit, which applies to battery storage when paired with solar. Your matched pro will analyze your energy usage and recommend the right battery configuration for your needs and budget.
