Spectrum Solar

See solar on your roof in about a minute.

Enter your address and see panels on your roof, system size, pricing, monthly payments, and savings. No contact info required.

Everything in one estimate

The same design software we use, pointed at your address.

Panels on your actual roof

Satellite imagery and 3D roof modeling place panels on your real roof planes — not a generic house — so you see how the system would actually look.

System size and production

How many panels fit, the system size in kilowatts, and how much of your yearly electricity it would cover, based on your roof's sun exposure and shading.

Cash, loan, and lease pricing

See every way to pay side by side — buying outright, financing with a solar loan, or a lease or PPA — with the real price for each.

Monthly payments

What a financed system costs per month, compared to what you're paying the utility now, so the trade is obvious.

Total savings over time

Estimated savings over the life of the system, and when it pays for itself.

No contact info required

You don't have to enter a phone number or email to see the estimate. Explore the numbers first; talk to us when you're ready.

How it works

Three steps.

1

Enter your address

The calculator pulls satellite imagery and models your roof — pitch, orientation, and shading — automatically.

2

Tell it your electric bill

Your average monthly bill sets the target: how much of your usage the system should cover.

3

Compare your options

See the panel layout, system size, cash vs. loan vs. lease pricing, monthly payments, and total savings. Save it, share it, or ask us to turn it into a formal quote.

Calculator questions

Is the solar calculator free, and do I have to give my contact info?

Free, and no. You only need your address and a rough monthly electric bill to see the full estimate — panel layout, system size, pricing, monthly payments, and savings. We only ask for contact details if you want us to turn the estimate into a formal quote.

How accurate is the calculator's estimate?

It's built on the same design software our engineers use, with satellite imagery and 3D roof modeling of your actual house, so it's far closer than a rule-of-thumb estimate. Your final quote can still move once we confirm the roof condition, your exact usage, and current equipment pricing on a site visit.

Does the calculator show financing options?

Yes. It shows cash, solar loan, and lease or PPA pricing side by side, with the estimated monthly payment for each and how that compares to your current utility bill.

What happens after I run the calculator?

Nothing, unless you want it to. You can save or share the estimate. If you'd like the real design and a written price, request a free quote and our engineers start from the calculator's layout.
