Address-based solar planning
What this instant solar quote calculator actually calculates
Generic calculators start with a ZIP code and an average home. NuWatt starts with the property, available roof data, and the electricity bill you enter. That produces a preliminary design you can inspect before deciding whether to save it and unlock exact preliminary economics.
Roof fit
Available aerial and roof data are used to place a preliminary panel layout on the selected home instead of assuming a generic roof area.
System and production
The layout is translated into an estimated panel count, DC system size, and annual production range sized around the bill you provide.
Savings and payment paths
Utility-rate context, equipment choices, and available payment paths inform the savings range; exact preliminary economics unlock only when you save the estimate.
Transparent by design
Estimate first. Verify before construction.
An online result is useful when it clearly separates modeled facts from facts that still need a site visit. NuWatt treats the instant quote as a planning estimate—not an engineering stamp, tax opinion, financing approval, or binding contract price.
For a deeper explanation of the inputs and uncertainty, read the solar estimate accuracy guide. If you already have a proposal from another installer, use the solar quote checker for a separate review.
Instant solar quote questions
What can I see before I provide contact information?
Start with a property address and average electric bill. When usable roof data is available, NuWatt shows a roof-specific panel layout, estimated system size, production, and a preliminary savings range before asking you to save the estimate.
Is an instant solar quote a final contract price?
No. It is a preliminary planning estimate. Roof condition, structural and electrical work, utility requirements, site access, final equipment, and incentive eligibility must be confirmed before a construction-ready proposal or contract.
What information do I need to start the solar quote calculator?
You need the property address and an average monthly electric bill. An actual bill or annual kWh history can improve later sizing and savings review, but a phone number is not required to start the roof analysis.
How does the calculator estimate the number of solar panels?
The preliminary design combines available roof and satellite data with the electricity use represented by your bill. It evaluates roof fit and proposes a system sized around current usage; a site survey and final engineering can change the panel count.
Can I compare panels, batteries, and payment options?
Yes. The design workspace lets you review available equipment and payment paths for the property. Exact preliminary economics are shown when you choose to save the estimate and provide the required contact and consent details.
Why can the final solar proposal differ from the online estimate?
A final proposal incorporates facts that an online model cannot fully verify, including roof condition, structural loading, electrical-panel scope, trenching or access, current utility rules, permitting, and confirmed incentive eligibility.
