Your custom estimate

What you'll see in your estimate

This isn't a generic calculator. The tool designs a system on a satellite image of your actual roof.

A panel layout on your roof

Placed to avoid shade from trees, vents and neighboring structures.

Estimated annual production

How many kilowatt-hours the system is expected to generate each year.

How much of your usage it covers

Based on the bill amount and utility you enter.

Battery storage options

For keeping the lights on during outages and using your own power after sunset.

Then, a clear next step

When you're ready, connect with our team for a detailed design and a firm proposal. Your online estimate is a starting point; we confirm roof measurements, electrical details and your usage history before anything is installed.

Start with my address

Built for the Southwest

One of the best places in the country for solar

Long summers, clear skies and afternoon air-conditioning loads make a rooftop system work harder here than almost anywhere else.

Sunlight is the fuel, and there's a lot of it

Arizona and Nevada are among the sunniest states in the country, and much of Texas isn't far behind. More sun means more electricity from every panel.

Big bills line up with big production

Summer cooling drives the highest electric bills of the year. That's exactly when a solar array produces the most.

A more predictable power cost

Utility rates change over time. Producing your own electricity gives you a predictable piece of your household budget.

Add a battery

Solar makes the power. A battery decides when you use it.

Many utilities in our service area charge more for electricity in the late afternoon and evening. A home battery stores your midday solar so you can use it when rates peak, and keeps essentials running if the grid goes down.

Backup during outages

Keep the refrigerator, Wi-Fi, lights and select circuits running through storm and heat-related outages.

Use your own power at night

Shift the energy you make at noon to the hours when your home needs it and the utility charges the most.

Sized for your home

Batteries come in modular sizes. We match capacity to the loads you care about most.

Common questions

Questions homeowners ask us

Is my roof a good fit for solar?

South-, west- and east-facing roof sections with limited shade perform best, but most homes in our service area have enough usable roof to make solar worthwhile. The estimate tool models your specific roof so you don't have to guess.

How accurate is an online estimate?

It's a strong starting point built from satellite imagery, local sun data, and the bill and utility information you provide. Before anything is installed, our team confirms roof measurements, electrical details and your usage history to finalize the design.

What happens to my utility bill?

You stay connected to the grid. Your solar system reduces the electricity you buy, and your utility's rules determine how any extra production is credited. We'll walk you through how your utility handles this.

Do I need a battery?

Not always. A battery adds outage protection and lets you use your own solar power in the evening, which matters more with some utility rate plans than others. The estimate lets you compare solar alone with solar plus storage.

How long does installation take?

The installation itself usually takes a day or two. Permitting, inspection and utility approval add time, and that varies by city and utility.

Your roof, your numbers, no pressure.
