Research data
Solar data downloads
The numbers behind the research pages as CSV: residential solar by state for 2024 and the US national series from 2014, free to reuse with attribution.
Written by HyreSolar Research Desk Primary-source research and fact checking
The short answer
Every figure on this site that we computed ourselves is downloadable, in two CSV files built from Form EIA-861. They are generated from the same dataset the pages read, at the moment the pages are built, so a number in a table and the same number in a download cannot drift apart.
Which solar datasets can I download?
Two CSV files, UTF-8, built from the Form EIA-861 2024 final release. Each card downloads the file; the page it feeds is linked below the cards.
See the files in use: solar by state reads the state file, and cost by system size reads the national series.
How can I reuse the data?
Use it, republish it, build on it. Two conditions make up the whole license:
The derived ratios, rankings and per-account arithmetic are ours, and that is what the attribution is for.
Or to hyresolar.com/research/. The underlying EIA data is US federal government output and in the public domain.
What are these numbers, and what are they not?
Columns marked HyreSolar calculation in the file headers are derived by us. EIA publishes the inputs (capacity, installations, residential sales, revenue and accounts), not these ratios. Treat them as our analysis of EIA data, not as official statistics.
Columns not marked that way are reported figures taken from the source files unmodified. The methodology page sets out how the derivation works and how it was validated.
Which data year do the files cover?
Form EIA-861 lags by about two years. These files are the 2024 final release, retrieved 2 September 2026. The partial 2025 early release is excluded, because mixing an early release into a series of final ones produces a break that looks like a finding.
When the next final release lands, the pipeline is re-run and the pages and these files update together.
Questions
What license applies to these downloads?
Why are the CSVs generated rather than stored?
Which columns are HyreSolar calculations rather than published figures?
Can I request a figure broken out differently?

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.
- 160
- primary sources read and cited
- 228
- figures with a retrieval date
- 115
- federal and state government sources
- 66
- researched pages published
How this desk works
- Primary sources only. Statutes from the legislature’s own publishing system, federal data from the agency that collects it, code text from the adopted edition, manufacturer claims from the data sheet. We do not cite an article that cites a source; we go and read the source.
- Every figure carries its provenance. A named document and the date we retrieved it, so you can check it and so you know how old it is. Retrieval dates are not decoration: an EIA rate from May is a different fact from an EIA rate from August.
- We publish what we could not verify. Every research page carries a section naming the things we tried to establish and could not, and why. A paywalled standard, a state website that refused the request, a manufacturer that publishes no figure at all.
- We separate measurement from modeling from our own reasoning, and label which is which on the page. A laboratory measurement, an assumption inside a modeling tool and our own inference are three different kinds of claim and they are never presented as one.
- We do not sell solar, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of Form EIA-861, 2024 final release. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
