Sonora Solar Engineering provides permit-ready PV designs, structural assessments, and interconnection support for residential solar installations across Arizona and the Southwest.
Beyond the obvious utility-bill reduction, residential solar delivers measurable financial, environmental, and resilience benefits, each backed by engineering precision.
We handle every technical deliverable. Your installer focuses on the physical work.
We look at your utility bills, roof shape, and any shading around your house to figure out the right system size for your home.
We design a solar layout built for your roof — where the panels go, what equipment we use, and how much power your system will produce.
We confirm your roof can safely hold the panels and prepare the electrical plans your installer needs to get to work.
We handle the paperwork with your city and your utility company so everything's approved before installation starts.
We're on call for your installer during the project, so any questions get answered fast and nothing slows down.
Our feasibility review is included in every project quote. If solar isn't the right fit, we'll tell you before any money changes hands.
South, west, or east-facing roof sections with at least 200 sq ft of usable area.
Roof age of 5+ years remaining (we assess if re-roofing before install is straightforward).
Monthly utility bills of $100 or more yield the strongest financial case.
No persistent full-day shading from trees or adjacent structures.
Most homeowners pay between $15,000–$30,000 for a full system before any incentives, depending on your home's energy use and roof size. We'll give you an exact number after a quick look at your electric bills and roof — no cost or obligation.
As of 2026, the federal 30% solar tax credit has ended for homeowner-owned systems, but a few savings are still on the table in Arizona:
• Arizona state tax credit — 25% of your system cost, up to $1,000
• Sales tax exemption — no state sales tax on solar equipment
• Property tax exemption — the added value solar gives your home is 100% exempt from property tax
• Net billing — your utility credits you for excess power your system sends back to the grid
Financing and solar leases are also available if you'd rather spread the cost out or skip the upfront investment entirely. We're happy to walk you through the numbers for your specific home.
