Exporting Solar Energy: Solar Savings with Battery Storage

Updated: October 1, 2025

Understanding Solar Export Rates in Arizona

Solar export rates are the payments Arizona homeowners get for the extra solar energy their systems create and send to the grid. These rates are determined by local utility companies and vary depending on the state, utility provider, and specific program. Exporting solar energy helps homeowners save on energy costs. They can earn credits or payments for the extra electricity they produce.

At Solar Topps, we are experts when it comes to Solar Energy in Arizona. While we serve the entire state of Arizona, we mainly serve the cities of Phoenix, Scottsdale, Paradise Valley, Mesa, Gilbert, Chandler, Fountain Hills, and Glendale.

Solar Export Rate Programs in Arizona

Arizona offers several programs to incentivize solar energy adoption and provide fair compensation for exported energy. Key programs include net billing and net metering, which differ in how exported energy is credited. While net metering provides a one-to-one credit based on the retail electricity rate, net billing credits are calculated at a lower rate, often referred to as an avoided cost rate. Understanding the specifics of these programs is essential for Arizona homeowners to make informed decisions about installing solar systems and maximizing their financial benefits.

Solar Adoption in Arizona

Arizona, known for its abundant sunlight, is one of the leading states in the adoption of solar energy. The state’s solar-friendly policies and clear skies make it an ideal location for residential and commercial solar installations. With programs like net billing and incentives that encourage renewable energy, Arizona continues to see significant growth in solar investments. Homeowners across the state are increasingly turning to solar systems to reduce energy bills and contribute to a sustainable future.

Solar Energy Initiatives Across Major Arizona Cities

Major cities in Arizona, such as Phoenix, Tucson, and Mesa, have implemented various initiatives to promote solar energy adoption. Phoenix, for instance, has launched aggressive sustainability programs aimed at increasing renewable energy use. Similarly, Tucson provides attractive incentives and streamlined permitting processes for solar installations. Mesa is also committed to expanding clean energy usage by encouraging solar adoption through local programs and education. These initiatives underscore the cities’ dedication to fostering environmental responsibility and economic savings for residents through solar energy.

Current Solar Buyback Rates in Arizona by Utility (APS, SRP, TEP)

Solar energy has become an increasingly popular choice for residents and businesses across Arizona, offering both environmental and financial benefits. With abundant sunshine year-round, the state is in a prime position to take advantage of solar power. Understanding the current solar buyback rates provided by major utility companies such as APS, SRP, and TEP can help individuals and organizations make informed decisions about solar adoption and how it can impact their energy costs and savings.

2025 Solar Buyback Rates for Major Utilities in Arizona

Below is an overview of the 2025 solar buyback rates for Arizona’s major utility providers:

Arizona Public Service (APS)

• Export Rate: $0.084 per kWh
• Notes: APS continues to offer its Resource Comparison Proxy (RCP) rate for customers with solar rooftop systems. This rate applies to excess energy exported to the grid.

Salt River Project (SRP)

• Buyback Rate: $0.058 per kWh
• Notes: SRP operates under a demand-based structure for solar customers, offering a lower export rate but competitive overall savings for net metering participants.

Tucson Electric Power (TEP)

• Export Rate: $0.087 per kWh
• Notes: TEP compensates customers at their avoided cost rate for excess energy. This rate is reviewed annually and may vary slightly by billing cycle.

These rates are indicative of the current efforts by Arizona utilities to promote solar energy while balancing grid management and cost efficiency. Customers are encouraged to contact their utility for the most recent updates or changes.

What is a Non-Export Solar System?

A non-export solar system is designed to keep the energy produced by solar panels from being sent back to the utility grid. Instead, all the electricity generated is used on-site, making it a great option for properties with high energy needs or limited grid access. These systems often include advanced energy management technology to ensure the solar energy is used efficiently with minimal waste. They are also commonly paired with solar batteries to store extra energy produced during the day for use later, like in the evening or during power outages.

Benefits of On-Site Solar Energy Systems

On-site solar energy systems provide several advantages, including energy independence and reduced reliance on the grid. This independence is particularly valuable in remote locations or areas prone to power outages. These systems can significantly lower electricity bills by utilizing renewable energy generated directly on-site, making them a cost-effective and sustainable solution over time.

Importance of Energy Storage Solutions

Pairing on-site solar systems with energy storage solutions, such as solar batteries, enhances their functionality and reliability. Energy storage allows excess energy generated during the day to be saved for future use, such as cloudy days or nighttime energy demands. This ensures a consistent power supply and maximizes the return on investment in solar technology.

Optimizing System Size for Solar Export Rates

It is often cheaper to design a system that covers about 60% of your electricity use. This is because export rates usually provide less financial benefit than net metering. This approach ensures that every kilowatt-hour produced is a kilowatt-hour saved from your utility bill. A skilled energy consultant can show different options. This will help you make a smart decision about Solar Export Rates. 

Leveraging Batteries for Optimal Solar Utilization 

To be completely self-sufficient with home electricity, you should add batteries to your solar system. This will greatly help you. Batteries provide a steady power supply by storing extra energy. This energy can be used during peak hours, at night, or during power outages. Batteries can increase your grid resiliency and reduce utility-supplied power dependency. With this setup, you could limit utility charges to unavoidable fees and local taxes. Details on how solar batteries can improve your solar system’s efficiency are available. This is especially true under export rate plans. You can find more information at SEIA’s Solar & Storage initiative.
