When To Go Solar: What Time of Year to Go Solar in AZ

Updated: May 6, 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.

By going solar in Arizona during these earlier months, homeowners benefit in several ways:

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.

What Months of the Year Should You Install Solar Panels in Arizona?

Timing plays a crucial role in planning solar panel installation in Arizona. Thanks to the state’s abundant sunshine, solar systems can be installed any time of year, but certain seasons offer distinct advantages in terms of efficiency and convenience. The optimal period typically falls between October and March, encompassing late fall, winter, and early spring. During these months, milder temperatures create ideal working conditions for installers, minimizing delays caused by Arizona’s intense summer heat. Moreover, installing your solar panels during this timeframe ensures your system is ready to maximize energy production during the high-output summer months.

Spring Months Going Solar:

Spring is the ideal season for solar panel installation, offering optimal conditions for efficiency and preparation. Key advantages include:

• Favorable Weather: Mild temperatures in spring reduce the risk of weather-related delays, ensuring a smooth installation process. 
• Peak Energy Preparation: Installing in spring allows your system to be fully operational before summer, when energy demand and sunlight hours are at their highest. 
• Maximized ROI: Strategic timing helps homeowners capitalize on increased energy production, optimizing returns on investment. 
• Avoiding Backlogs: By scheduling installation before peak periods, you minimize delays and ensure a streamlined process.

This approach ensures a reliable, efficient installation while positioning your system for maximum performance during high-demand months.

Benefits of Solar Energy During Summer

Summer is the perfect time to maximize solar energy. Longer daylight hours allow solar panels to produce more power, reducing reliance on the grid and cutting utility costs. Excess energy can be stored or credited through net metering, providing year-round savings. Upgrading your system before peak summer rates ensures greater energy independence and financial benefits.

The Fall and Winter Months Going Solar: Does Demand Change?

During the fall and winter months, solar energy production naturally decreases due to shorter daylight hours and less intense sunlight. However, this does not mean going solar is any less valuable. Modern solar panels are designed to perform efficiently even in low-light conditions, ensuring consistent energy generation. Additionally, many households consume less electricity during these cooler months, which can balance out the reduced solar output.

For systems equipped with energy storage, excess energy generated in sunnier months can be utilized, maintaining energy independence and offsetting utility costs throughout the year. This highlights the year-round practicality and benefits of a well-designed solar energy system.
