Arizona Home Battery Storage | APS & SRP Battery Savings
Power Your Home Smarter with Battery Storage
Arizona homeowners are leading the way in solar adoption, but solar panels alone aren’t enough to maximize your energy savings. With home battery storage, you can store excess solar energy during the day and use it later when the sun goes down or when utility rates peak.
At PGT Energy Solutions, we specialize in helping Arizona residents achieve true energy independence with smart battery backup systems from trusted brands like Enphase and Tesla. Whether you’re in Tempe, Phoenix, or across the APS and SRP service areas, a home battery can dramatically reduce your electricity costs and protect you from power outages.
Arizona Home Battery Storage FAQs
1. What Is Arizona Home Battery Storage and How Does It Work?
Home battery storage systems, such as Tesla Powerwall or Enphase Encharge, store excess electricity that your solar panels generate during the day. When your panels stop producing, at night or on cloudy days, your home draws power from your battery instead of the grid.
This process allows Arizona homeowners to:
Use stored solar energy during expensive peak hours.
Keep power on during grid outages.
Gain independence from utility price fluctuations.
2. How Do APS Battery Savings Work?
If you’re an APS (Arizona Public Service) customer, you may qualify for APS battery savings programs that help offset installation costs or reduce time-of-use rates.
By discharging stored energy during APS’s peak hours, your battery can help lower your demand charges, the extra fees based on your highest energy use during a billing cycle.
Key benefits of APS battery savings include:
Lower energy bills through optimized load shifting.
Eligibility for utility incentives.
A smarter way to use solar energy efficiently.
3. How Do SRP Battery Savings Help Reduce My Energy Costs?
SRP (Salt River Project) offers similar opportunities through SRP battery savings programs and demand-based plans. With the right setup, you can use your battery to power your home during SRP’s peak rate windows, when electricity is most expensive, and recharge during off-peak hours.
This approach, known as time-of-use optimization, makes it possible to save thousands over the life of your battery system.
4. What Is Demand Charge Reduction and Why Is It Important?
For many Arizona homeowners on APS or SRP rate plans, demand charges can be a major part of their bill. These charges are based on your highest 15–30 minutes of energy usage in a billing cycle.
A battery storage system helps by supplying power during those high-demand periods, preventing those spikes and leading to significant cost reductions.
This process is called demand charge reduction, and it’s one of the smartest ways to manage your home’s energy consumption.
5. What Is a Time-of-Use (TOU) Battery System?
A time-of-use battery system is programmed to automatically charge and discharge based on utility rate schedules.
Here’s how it works:
It charges during off-peak hours when electricity is cheap.
It discharges during peak hours when rates are high.
This type of system maximizes savings under APS or SRP time-of-use rate plans, giving you full control over when you draw energy from the grid.
6. What Are the Best Home Battery Brands for Arizona?
At PGT Energy Solutions, we recommend top-rated, warranty-backed systems designed for the Arizona climate and grid structure:
Tesla Powerwall – Sleek design, seamless app monitoring, and reliable whole-home backup.
Enphase Encharge – Modular and expandable battery storage that integrates perfectly with Enphase solar microinverters.
Both systems offer excellent battery backup capabilities for Tempe, Phoenix, and the surrounding metro area.
7. How Does Battery Backup Protect My Home During Power Outages?
Arizona’s intense heat, storms, and occasional grid interruptions make battery backup a valuable investment. When the grid fails, your battery backup system keeps essential appliances lights, refrigerator, internet, and medical equipment, running smoothly.
For Tempe homeowners, a battery backup system adds peace of mind and long-term protection against blackouts.
8. Are There Financial Incentives for Arizona Home Battery Storage?
Yes! Homeowners in Arizona can take advantage of multiple incentive programs and tax credits:
Federal Solar Investment Tax Credit (ITC) — Claim up to 30% of the battery system cost.
APS and SRP battery savings — Utility-specific rebates and rate benefits.
State incentives — Periodic Arizona programs that support renewable adoption.
These savings help shorten the payback period and increase your long-term return on investment.
9. Is Home Battery Storage Worth It for APS and SRP Customers?
Absolutely. If you’re under time-of-use or demand-based rates, a battery system can save you hundreds to thousands each year.
Plus, with a 10- to 15-year lifespan, your system continues to pay dividends long after it’s installed — reducing bills, adding home value, and enhancing energy security.
