About Solar Panel Cost by State

Our Mission

Help homeowners understand true solar installation costs and ROI by state, using NREL and EIA data rather than installer estimates.

Data Sources

All data on this site comes from authoritative, publicly available sources:

• NREL Solar API — primary data source that powers all data on this site
• EIA

We do not manufacture or estimate data. Every figure comes directly from the source APIs or published datasets.

Who We Are

We are a small team of data engineers and web developers who believe that government-collected public data should be accessible to everyone — not locked behind paywalls or buried in PDFs.

We build data-driven tools that surface useful insights from free public datasets: Census data, BLS statistics, NREL energy research, USDA nutrition databases, NPS park information, and more.

Data Accuracy

We update our data regularly from the source APIs. While we strive for accuracy, this site is intended for general reference purposes and should not be used as the sole basis for major financial or safety decisions.

For official data, always verify directly at the source:

• NREL Solar API
• EIA
