The numbers behind the research pages, as CSV. Free to reuse with attribution.
Last updated .
Every figure on this site that we computed ourselves is downloadable. The files below are generated from the same dataset the pages read, at the same moment the pages are built, so a number in a table and the same number in a download cannot drift apart.
states-2024.csv One row per jurisdiction: systems, capacity, accounts, household penetration, average system size, residential price, consumption per account, battery attachment, third-party-owned share, additions and five-year growth.
51 rows · 13 columns · CSV, UTF-8
national-2014-2024.csv One row per year: cumulative and added systems, capacity, average system size, household penetration, average residential price, accounts, PV-paired storage and third-party-owned installations.

Use them. Republish them. Build on them. We ask for two things, which is the whole licence:
The underlying EIA data is US federal government output and is in the public domain. What we add is the derivation — the ratios, the rankings and the per-account arithmetic — and that is what the attribution is for.
Columns marked HyreSolar calculation in the file headers are derived by us. EIA publishes the inputs — capacity, installations, residential sales, revenue and customer accounts — and does not publish 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 without modification.
The methodology page sets out how the derivation works and how it was validated, and the state-page method note lists the limitations that apply to every figure here.
Form EIA-861 lags by roughly two years. These files are the 2024 final release, retrieved 2 September 2026. The partial 2025 early release is deliberately 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 we re-run the pipeline, and the pages and these files update together.
If you want a figure broken out differently — a different year, a subset of states, or a derivation we have not published — ask. We would rather give you the cut you need than have the number reconstructed incorrectly from a chart.
