In the US solar market a CRM is almost never “just a funnel.” The cycle runs through site survey, system sizing, a bankable proposal, loan / lease / PPA quoting, then install, PTO, and O&M. That is why a generic CRM and a vertical solar platform do not play the same game — and this comparer puts both on one ranking, with explicit weights.
There is a third group that is easy to confuse in a demo: complementary tools (field ops hubs, canvassing apps, design engines wired into someone else’s CRM). They enter the same ranking on the same yardstick. A product that only builds PDFs loses on messaging and O&M on purpose; a product that only schedules trucks loses on proposals. The score does not say “bad product” — it says what the product is.
Native messaging (SMS/inbox on the lead, or WhatsApp Business API) is on the yardstick. Marketplace apps and website chat buttons do not count. Proposal and financing still weigh more than messaging — US solar pain is the proposal and the lender, not Meta chat.
A daily rotation re-reads official pages in this cut — one category per day — price, trial, new module, URL that disappears. The box at the top says what changed and what stayed the same, so you do not have to open every vendor site. The order only moves when the public source changes the product.
