How to Lower Your APS or SRP Bill with Solar and Battery Storage

Our team at Phoenix Valley Solar can help you navigate these incentives and maximize your savings. You can also use our Arizona Solar Calculator to get an estimate of your potential benefits.

Electric bills across Arizona are rising—and not just because of how much electricity you use. For many homeowners in the Phoenix metro area, the rate plan you’re on with APS or SRP can dramatically affect your total monthly cost.

That’s where solar battery storage in Phoenix comes in. By combining solar panels with battery backup, homeowners in Scottsdale, Mesa, and beyond can take control of when they use grid electricity, reduce peak-time charges, and optimize their energy usage under utility rules.

Understanding Time-of-Use (TOU) and Demand-Based Rates

Both APS and SRP have shifted most residential customers to time-of-use or demand-based billing plans. That means:

• Electricity costs more during specific hours, usually in the late afternoon and evening.

• Your monthly charges may be based on the single highest hour of usage each month, not just total usage.

This makes when you use energy almost as important as how much you use.

Without a solar battery, your solar panels only help during daylight hours. After sunset—when utility rates peak—you’re back to pulling expensive electricity from the grid.

How a Battery Changes the Equation

A solar plus battery system in Phoenix stores excess solar energy produced during the day and saves it for when it’s most valuable—like the early evening when rates spike.

Here’s how it helps:

• You avoid buying expensive electricity during peak hours.

• You reduce your demand charge by limiting high usage within a one-hour window.

• You protect yourself from surprise costs tied to APS or SRP rate changes.

• You increase the value of your solar system by using more of your own energy.

Battery storage is no longer just for backup. It’s a tool for smart energy billing.

Tesla Powerwall: Smart Battery Management

Tesla Powerwall installation in Phoenix is one of the most efficient ways to manage your time-of-use exposure. With the Tesla app, you can:

• Set your battery to “Time-Based Control” mode to automatically charge and discharge based on peak periods.

• Track your solar production, grid usage, and battery performance in real time.

• Prioritize backup for outages or savings—depending on your preferences.

This automation helps homeowners in Mesa and Scottsdale stay one step ahead of their utility bill.

Real-World Savings with a Battery System

Homeowners across Arizona who add battery storage to their solar system are seeing:

• Lower monthly utility bills under TOU plans

• More consistent electricity costs, even during high-demand summer months

• Reduced demand charges from limiting their peak-hour usage

• Better performance from their solar panels, especially in the evenings

If you’re on an APS Saver Choice plan or SRP’s E-27 or Customer Generation plan, a battery gives you more flexibility—and more control over your costs.
