Mesa Solar and Batteries: Check Your Electric Provider First
Before comparing solar or home batteries in Mesa, check the electric provider shown on your bill. The City of Mesa electric utility and SRP have different programs. Your street address alone does not tell you which rules apply.
City of Mesa’s FY2026–27 residential limits
The city’s published solar program lists these limits:
Without storage: up to 5 kW of PV module capacity and 5 kW of inverter capacity.
With storage: up to 10 kW of PV module capacity and 11.5 kW of inverter capacity.
The city bases inverter limits on rated capability. Programming a larger inverter to a lower output is not accepted as compliance. Confirm the proposed equipment and application with the utility before installation.
What about net metering?
Mesa’s current program provides net metering for qualifying residential systems, subject to program requirements and size limits. The city reviews program provisions and approves credits by fiscal year. Confirm your applicable agreement and current terms before making a purchase.
Does adding a battery provide outage power?
Solar panels alone usually cannot power a home during a utility outage. Backup operation requires additional compatible components and appropriate design. Ask your installer which circuits will operate, whether air conditioning is included, and how long usable capacity can support the selected loads.
Permits and utility approval matter
Mesa states that projects including a battery or meter-panel upgrade require a Development Services permit. Its published process includes design review, installation review and interconnection before permission to operate. A construction completion date is not a guarantee of utility authorization.
If SRP serves your home
Use SRP’s current plan, export and interconnection rules instead. Do not apply the City of Mesa capacity limits or net-metering provisions to an SRP-served property.
Your starting checklist
Electric provider and exact rate plan.
Existing solar panel and inverter specifications.
Recent bills and available usage data.
Appliances you want backed up and intended outage duration.
Written confirmation of permits, program eligibility and operating requirements.
Contact Backup Ready Arizona to discuss your home and ask about local provider availability, or compare backup options.
