Corrections

By Mike YuPublished September 7, 2026

Why this page exists

This site asks you to believe numbers about your electricity bill, and the only reason to believe them is that the working is public and checkable. A site that shows its arithmetic but silently rewrites it when it's wrong has given you nothing.

So corrections are published rather than absorbed. If a change makes an earlier version of a page look bad, that is the correction working.

What counts as one

A correction is a change to a fact: a price, a rate, a production figure, a legal status, a certification claim, a date. These get logged below with the old value and the new one.

Not a correction: rewriting a sentence, adding a section, updating a page because the world changed rather than because we were wrong. A rate that goes up is news, not an error. The SB 868 status changes on its own schedule and is dated wherever it appears.

If a correction changes a savings figure, the methodology and the calculator change with it in the same commit. An article stating arithmetic the calculator can't reproduce is precisely what this site tells you to watch out for, so the tests fail until both agree.

The log

Nothing has been corrected since publication.

That is not a boast — the site is new, and the honest reading is that not enough people have checked it yet. The items below were caught before launch and are recorded here because they are the kind of thing this page is for.

DatePageWhat changed
1 Sep 2026CraftStromPrice per watt was given as "roughly $1.60 a watt" for a $2,031 800-watt kit. That arithmetic is wrong: it is $2.54 a watt. Corrected before publication
1 Sep 2026How much does it saveWorked example 6 read $356. The model produces $355 — the $356 came from multiplying an already-rounded figure. Corrected, and there is now a test asserting all nine worked examples against the model so the two can't drift again
1 Sep 2026FAQSaid "thirty answers" and had thirty-five
1 Sep 2026Is it legal?The answer box restated the SB 868 status word for word, which would have gone stale the moment the Governor decided. Rewritten to state only what stays true, with the changing part left to the status strip

Email us. A correction is the most useful thing you can send, and you don't need to be sure — "this doesn't look right" is enough to make us check.

If you're right, it goes in the table above with your correction noted. If you'd rather not be credited, say so and we'll leave your name out.
