Methodology
Every row is a verbatim sentence read from the named source's own page through the estate's fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).
2 of the 25 named sources that could be read published a usable figure; 23 published none and are recorded as not published, never filled in; 0 could not be read (blocked, dead or unreachable) and count nowhere.
The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 116 candidate sentence(s) were refused by a reviewer with the reason recorded.
Derivation as chartered: the published price of the work rather than the box: installation labour (hours and dollars), the annual service plan, the replacement-filter and salt cost per year, and the certified-laboratory test per panel; reduced to a total cost of ownership per system type over five and ten years, which is the number that actually decides a purchase and which nobody publishes because the box and the job are sold by different people.
Beside it, the share of installers and labs that publish a price at all, and the spread between a national chain's flat rate and the local band.
116 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
