Texas Installed Cost Index

Every row is a verbatim sentence read from the named source's own page through our 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).

12 of the 37 named sources that could be read published a usable figure; 25 published none and are recorded as not published, never filled in; 3 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in USD (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 13 figures, never sentences; 472 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): the median, minimum and maximum ADVERTISED installed price per watt for Texas, per metro and per system size, computed across every company that publishes one on its own site - with the share that publishes at all beside it.

Three things nobody publishes together: the spread between the cheapest and dearest published Texas figure (the harvest that wrote this charter read $2.13/W to $3.18/W claimed for the same state in the same month), the gap between what installers publish and what the marketplaces publish as the state average, and the second price line - the DIY kit, equipment without labour - set against the installed figure.

Repriced-since on every read, and a company that publishes nothing is recorded not-published, never estimated.

472 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
