Why Phoenix’s Climate Is Perfect For Solar Energy
With over 300 days of sunshine each year, Phoenix and the surrounding Maricopa County is one of the premier locations in the entire country for solar power installation. The unique desert climate creates ideal conditions for maximum solar energy production year-round, giving homeowners in the Phoenix valley unprecedented opportunities to harness this abundant natural resource.
Top Reasons To Go Solar In Phoenix, Arizona
1. Dramatically Lower Energy Bills
Solar panels significantly reduce your electricity costs, especially in Arizona where air conditioning usage drives high utility bills. Phoenix homeowners with properly designed solar systems typically reduce their grid dependency by 70% or more. Many of our clients see their monthly electric bills drop from $200-300 to just $50-60 during peak summer months.
2. Energy Independence from Rising APS and SRP Rates
Arizona electricity rates have increased 15.3% in just two years with further increases approved by the Arizona Corporation Commission.1 Solar panels reduce your reliance on APS, SRP and other utilities, effectively locking in your energy rates for decades. As Phoenix continues to grow and energy demand increases, solar owners enjoy protection from the inevitable rate hikes.
3. Boost Your Maricopa County Property Value
Recent 2024 research from SolarReviews found that Arizona homes with solar installations sold for 4.8% more on average than comparable homes without solar.2 For the median Phoenix-area home, this translates to a remarkable $23,952 increase in property value!3 With an average solar system price of only $19,000, Maricopa County homeowners immediately realize a $4,952 return on investment—even before considering energy savings.
4. Arizona-Specific Tax Incentives & Rebates
Phoenix homeowners can take advantage of generous tax incentives that significantly reduce installation costs:
Federal Solar Investment Tax Credit (ITC) – 30% off your entire system cost4
Arizona State Tax Credit – Up to $1,000 additional savings5
Net Metering Benefits – Sell excess energy back to APS, SRP and other utilities
Local Utility Rebates – Additional incentives available for Maricopa County residents
Important: These Phoenix solar incentives are scheduled to decrease in the coming years. The Arizona state credit and utility rebates are subject to annual funding caps that often run out early in the year, while the federal tax credit will begin stepping down after 2032.

Solar System Costs in Phoenix, Arizona
The cost of solar in Maricopa County varies based on system size (kW), equipment quality, and installation complexity. For Phoenix-area homes, an average sized solar system (7.6 kW) should cost approximately $19,000 before incentives.
Many solar companies in Phoenix employ aggressive sales teams with high-pressure tactics, often leading homeowners to pay inflated rates.

Frequently Asked Questions from Phoenix Homeowners
How long does solar installation take in Phoenix?
Most of our Maricopa County installations are completed within just 3-4 days, with the entire process from consultation to activation typically taking 4-6 weeks. Our team handles all permitting, HOA approvals, inspections, and utility coordination to ensure a smooth, hassle-free experience for homeowners across Phoenix, Scottsdale, and the entire Valley.
Will solar panels damage my Phoenix home’s roof?
No. Our installation methods are specifically designed for Arizona’s unique roofing styles and actually provide protection by shielding portions of your roof from the intense Phoenix sun. Unlike other installers using cheap caulking, Under The Son utilizes a triple layer of protection with a butyl coating, Geocell roof sealant, and flashing for roof penetrations.
How do solar panels perform in Phoenix summer heat?
While extreme heat can marginally reduce panel efficiency, the significantly longer daylight hours and intense sun exposure in Phoenix more than compensate, resulting in excellent year-round energy production.
How do I maintain solar panels in dusty Phoenix conditions?
Arizona’s regular rainfall actually helps keep panels relatively clean. For optimal performance, we recommend a professional cleaning 1-2 times per year to remove accumulated desert dust.
