FAQ
What does the Solar Estimator estimate?
Solar Estimator gives you a planning-stage cost range to work from before you sign a solar contract. Compare the range against any quote you receive and ask a line-item breakdown if a bid sits well above or below it — this is where pricing games usually show up.
What should I check before comparing quotes?
If your quote is below this range: verify the system size (kW) and panel/inverter brands. Low quotes sometimes use lower-tier equipment or assume you'll claim the federal ITC yourself. If your quote is above this range: ask what's included beyond panels — interconnection fees, roof reinforcement, monitoring, and battery are major cost drivers that should be itemized.
Is this a quote from a provider?
No. This page is an estimation tool for planning only. It helps you compare scenarios using your inputs and local context, without claiming provider availability or pricing guarantees.
