Free solar estimator

See your home’s solar estimate in about a minute.

Enter your address and electric bill. We’ll identify the state, check the roof, and size a preliminary solar offer.

✓ No contact details to see a result ✓ Address-specific roof check ✓ State-specific preliminary offer

The homeowner does not purchase the equipment. Utility charges and electricity not offset by solar remain the homeowner’s responsibility. Final eligibility and written terms apply.

Step 1 of 2

Start with your home

Property address We use the full address to identify the state and locate rooftop data.

Property type Existing rooftop solar?

Roof size measured automatically

We’ll match the address to Google aerial rooftop data when you continue.

Typical monthly electric bill

This is used to estimate annual electricity usage and avoid recommending an oversized system.

We record anonymous progress through this estimator (for example, when a result is shown) to improve the campaign. We do not save your address, bill, or roof details unless you request a proposal below.

Preliminary estimate ready

Your preliminary solar estimate.

Estimated PPA amount $0 Final eligibility and written PPA terms apply

Annual electric-bill savings $1,680–$2,280 Before loan payments, preliminary first-year range

A preliminary estimate only. Final property eligibility, scope, price, utility approval, and written PPA terms must be confirmed.

The electricity cost per kWh used for sizing and savings is a best estimate, not the customer’s actual utility rate.

Estimated annual savings after financing With $0 due upfront, you could save up to $0 in Year 1

Year 10$0 per year

Year 20$0 per year

Year 10 and Year 20 compound the high end of estimated electric-bill savings by 3.5% annually and subtract the same illustrative annual payments on a 20-year loan at 8.5%. This assumes no down payment or financing fees and unchanged usage and solar production. It is not a financing offer or guaranteed savings. Actual approval, APR, fees, utility costs, production, and savings may differ.

Estimated monthly savings$140–$190

Usage-matched system size8.2 kW

Estimated annual production9,840 kWh

Roof maximum potential12.4 kW

Current electric bill$250

Estimated remaining utility charges$85–$110

Why this result?

How this estimate works

This preliminary tool uses address-specific roof data when available and an illustrative state residential electricity value to recommend a system size. A final proposal must use the customer’s actual rate and usage history. Shading, roof condition, orientation, usage, final design, interconnection, and utility rates can change the result.

Important terms and disclosures

This is a preliminary educational estimate, not approval, a binding offer, or guaranteed savings. A final proposal requires ownership verification, aerial analysis, roof and electrical review, actual usage history, utility approval, and final PPA terms. Customers continue to pay applicable utility charges and for electricity not offset by solar.

Under the advertised PPA, Nextgen Solar LLC or its designated system owner owns and maintains the solar system and receives all SRECs and available system-owner tax benefits. The homeowner does not own the system, receives no SRECs, and cannot claim tax benefits associated with system ownership. Unusual homeowner-requested or homeowner-caused work, pre-existing roof or structural work, property transfer, early termination, or default situations are governed by the final agreement and may create separate costs.
