Arizona’s Solar Advantage in 2026

Arizona continues to lead the nation in solar potential, offering businesses unmatched conditions for generating clean, affordable electricity. With more than 300 sunny days per year, the state’s unique climate and geography make it a powerhouse for solar generation, especially in the commercial sector.

Solar Resource Abundance

The foundation of Arizona’s solar appeal lies in its solar irradiance levels. The state’s high levels of direct sunlight mean that photovoltaic (PV) systems installed on commercial properties generate more electricity per panel than in most other parts of the country. This leads to faster payback periods and higher long-term returns on investment.

Over 300 sunny days annually
High solar irradiance improves energy yield
Consistent performance year-round due to minimal cloud coverage

For businesses evaluating long-term energy investments, this abundance translates directly into lower utility bills and improved energy independence.

Market Capacity and Large-Scale Potential

Arizona has already proven its capacity for large-scale solar generation. Projects like the 280 MW Solana Generating Station, which uses concentrated solar power (CSP) with molten salt storage, showcase the state’s ability to support both photovoltaic and thermal solar technologies on a massive scale.

According to industry analysis, Arizona has the physical and solar resource capacity to host thousands of gigawatts of PV and CSP, far exceeding current demand. This positions the state as a long-term hub for clean energy development.

Policy and Regulatory Changes Impacting 2026

While Arizona’s natural solar potential remains strong, 2026 brings significant policy shifts that affect how businesses approach commercial solar. Regulatory changes are altering the incentive landscape and reshaping how solar systems interact with the grid.

Repeal of the Renewable Portfolio Standard (RPS)

In 2025, the Arizona Corporation Commission (ACC) voted to repeal the state’s Renewable Portfolio Standard, which had previously required utilities to source 15% of their energy from renewables by 2025. This repeal removes a key driver of utility-scale solar investment and has ripple effects on commercial projects that relied on utility incentives tied to RPS compliance.

Without the RPS, businesses must rely more heavily on federal incentives and direct financial returns to justify solar investments. Strategic planning becomes more important than ever to maximize system value.

Net Metering vs. Net Billing

Arizona has shifted away from traditional net metering toward net billing, where solar system owners are compensated at a lower, often wholesale, rate for excess electricity sent to the grid. This change impacts the economics of commercial solar, reducing the value of exported energy.

Net billing reduces payback for oversized systems
Emphasizes the importance of right-sizing systems to match on-site consumption
Encourages energy storage to maximize on-site usage

Understanding rate structures and working with experienced providers is critical to designing cost-effective systems under the new rules.

Solar Rights and Permitting Laws

Arizona remains one of the most solar-friendly states in terms of property rights. Laws prevent homeowners’ associations (HOAs) and other entities from banning solar installations entirely. For commercial projects, permitting is more complex, involving building codes, electrical standards, and sometimes utility interconnection agreements.

Arizona Revised Statutes (ARS) protect solar access rights
Businesses must navigate local permitting processes
Experienced contractors help avoid delays and compliance issues

System Types and Installation Trends in Arizona

As businesses adopt solar in 2026, a variety of system types and deployment methods are being used to meet site-specific needs and energy goals.

Rooftop, Ground-Mounted, and Solar Carports

Commercial solar installations in Arizona typically fall into one of three categories:

Rooftop systems: Ideal for warehouses, retail buildings, and offices with flat or low-slope roofs
Ground-mounted arrays: Suited for businesses with ample unused land, such as manufacturing facilities
Solar carports: Provide dual benefits of shaded parking and power generation, popular in schools, hospitals, and corporate campuses

Each system type has unique design and engineering considerations. Site constraints, local zoning rules, and energy consumption patterns influence the best choice for each business.

Energy Storage and Smart Integration

Battery storage is becoming a core component of commercial solar systems in Arizona. As grid compensation decreases under net billing, storing excess energy for later use increases system value and reliability.

Batteries help manage demand charges during peak times
Improve energy resilience during outages
Support time-of-use arbitrage under variable rate structures

Integrating solar with energy management software also allows businesses to optimize usage patterns and improve ROI.

Turn-Key EPC Services

To simplify the process, many businesses are turning to turn-key engineering, procurement, and construction (EPC) providers. These companies manage the entire project lifecycle from design and permitting to installation and system commissioning.

Streamlined project management
Faster timelines and fewer permitting issues
Single point of accountability

Working with a full-service provider ensures consistency and reduces the risk of cost overruns or delays.

Financial Outlook and Incentives in 2026

Despite policy shifts, commercial solar in Arizona remains financially attractive in 2026 due to a variety of federal incentives and financing mechanisms.

Federal and State Tax Credits

The 30% Investment Tax Credit (ITC) continues to be a major financial driver for commercial solar. While Arizona’s state credit is limited and primarily benefits residential users, the federal ITC significantly reduces upfront costs.

Must be claimed in the year the system is placed in service

MACRS and Bonus Depreciation

The Modified Accelerated Cost Recovery System (MACRS) allows businesses to depreciate the cost of a solar system over five years, with bonus depreciation available for systems installed in 2026.

Accelerated depreciation improves cash flow
Can reduce tax liability in the early years of system operation

Timing installations to align with fiscal planning can enhance financial outcomes.

Financing Options for Businesses

Commercial solar buyers in Arizona have multiple financing options:

Loans: Allow businesses to own the system and claim all tax benefits
Leases: Reduce upfront costs but shift tax credits to the lessor
Power Purchase Agreements (PPAs): Third-party ownership models with predictable electricity prices over time

Each model has trade-offs in terms of ownership, savings, and tax benefits. A qualified financial advisor or solar provider can help determine the best fit.

Market Challenges and How to Overcome Them
