The same assistants, the same week, three phrasings of one need — ranked separately. A business that wins “best” but loses “most affordable” is losing a different customer each time.

No business can pay to be ranked · how this is measured
Is your business in this answer?
12 assistants answered “Who are the best solar installers in San Jose, CA?” this month and named 25 solar installers in San Jose, CA. Which side of that list you are on decides whether a customer asking that question ever hears your name.
On the list, and want to be higher?
Rank here is set by how many assistants repeat your name and which sources they read to decide it — the 25 sources above are the ones that shaped this answer. Our platform measures exactly that for one business: the same 12 assistants, daily instead of monthly, which of those sources you appear on and which you don't, and every fix tracked until the answer changes.
You're not on the list
Then for this question you were not in the answer at all — not ranked low, absent from the shortlist, with nothing to tell you it happened. That is the ordinary case: most solar installers in San Jose, CA are never named. AI Pulse shows you what each assistant says about your business and what to change so it names you.
Common questions
Who is the best solar installer in San Jose, CA, according to AI?
As of October 1, 2026, Tesla Solar — named by 8 of the 10 AI assistants that answered (12 asked), 16 times in all. Sunrun and Clean Solar rank next.
How many solar installers did AI assistants name in San Jose, CA?
46 businesses were named across 36 answers from 10 assistants, on 3 phrasings of the question. 25 of them were named often enough to rank.
How often is this ranking updated?
Every month. This edition covers October 2026; the next one publishes in November 2026. Each business's move since the last edition is shown in the "vs last month" column.
How is this ranking measured?
Fixed, unbranded consumer questions — including "Who are the best solar installers in San Jose, CA?" — are put to the same assistants every month. Named businesses are resolved to one entity, a name mentioned only once is dropped as unverifiable, and a cell publishes nothing until enough answers accumulate. No business can pay to appear or to rank higher.
The questions we ask
The prompt set is fixed and unbranded, so month-over-month movement means the assistants changed their answer — not that we changed the question.
- Who are the best solar installers in San Jose, CA?
- I need a solar installer in San Jose, CA. Who do you recommend?
