The Best Time of the Year to Install Solar Panels in AZ

Updated: September 26, 2025

Going solar in Arizona: why we recommend going solar quickly after you decide it is right for your family. Over the last several years, we have witnessed changes in utility rate structures, net-metering incentives, and rebate programs that made going solar “tomorrow” slightly less attractive than making the decision “today.”  

Despite these changes, however, going solar in Arizona still makes a lot of economic sense for many homeowners throughout the state, and Solar Topps is proud to have the opportunity to serve them. The key difference with our company is if solar does not make sense for you and your family, we will let you know. We are part of your community and value, honest and open relationship with our neighbors over a sale. Although “yesterday” was a better time to go solar, customers who decide to go solar earlier in the year, between January and May, tend to be happier with their overall experience.

At Solar Topps, we serve the entire state of Arizona.  However, we do specialize in the Phoenix Metro Area in cities like Scottsdale, Paradise Valley, Buckeye, Gilbert, Mesa, Chandler, Buckeye, Glendale, and other cities in the West Valley.

How much are Solar Panels for Homes?

The cost of installing solar panels on your home is not a one-size-fits-all figure. It varies significantly based on several critical factors, including system size, panel efficiency, installation complexity, and available incentives. Understanding these variables is crucial for homeowners to accurately assess their potential investment and long-term financial benefits.

Key Factors Determining Solar System Costs

1. System Size
   The size of the solar system you choose is one of the most significant factors impacting costs. Larger systems with higher energy output will naturally cost more upfront but may result in greater long-term savings by reducing reliance on traditional energy sources.
2. Panel Efficiency
   Solar panels come in various efficiency ratings, which determine how effectively they convert sunlight into electricity. High-efficiency panels tend to have a higher initial cost but can generate more power in less space, making them ideal for homes with limited roof area.
3. Installation Complexity
   The complexity of the installation process can also affect costs. Factors such as roof type, orientation, shading, and structural integrity can influence the difficulty of installation and the labor required, potentially increasing overall expenses.
4. Available Incentives and Rebates
   Many homeowners can offset the cost of a solar system by taking advantage of federal, state, and local incentives. Tax credits, rebates, and net metering programs can significantly reduce the financial burden and shorten the payback period.

By carefully evaluating these factors and consulting with a qualified solar provider, homeowners can make informed decisions and optimize both their upfront investment and long-term energy savings.

Maximizing Savings with Solar Incentives

Selecting a reputable and experienced solar installation company is critical for maximizing the benefits of your solar investment. Begin by researching providers in your area and comparing their services, warranties, and customer reviews. Look for companies with a proven track record in designing and installing efficient and durable solar systems. Additionally, verify that they are licensed, insured, and certified by recognized organizations such as the North American Board of Certified Energy Practitioners (NABCEP). A reliable company will conduct a thorough site assessment, provide clear and honest pricing, and assist with navigating incentive programs and permitting requirements. Taking the time to choose the right company ensures a smooth installation process and the long-term functionality of your solar energy system.

Homeowners Benefit from Going Solar in Off-Peak Months

1. Electric bills are lower this time of year, so customers waiting for installation pay little to the Utility company.
2. During this time of year, fewer people choose solar, resulting in reduced demand on resources at Utilities, Cities, and HOAs. This allows for quicker processing of applications. With faster installations, homeowners can have their systems up and running before summer, enabling them to reduce electric bills when it matters most and start saving sooner. 
3. To take advantage of tax credits and incentives for going solar in Arizona, ensure your system is installed and operational by year-end to claim the tax credit promptly.
