What Solar Costs bronze

whatsolarcosts.com

“Estimates the installed cost, system size, payback period and 25-year net benefit of a residential rooftop solar system in the United States, from a US state and an average monthly electricity bill. Educational modelling from published state-level assumptions — it is not an installation quote and it collects no personal information.

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Google Trust Services domain-validated
Valid until 31 Dec 2026 as of our check on 8 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of whatsolarcosts.com controls every word below.

Residential solar cost estimate

Given a US state and an average monthly electricity bill, returns system size in kW, installed cost range, federal tax credit, year-one savings, payback range and 25-year net benefit, plus a results URL the homeowner can open. Optional inputs: roof shading (light, moderate, heavy), target offset (0.75, 0.9, 1) and battery (boolean). The bill must be between $30 and $2000 per month. Send the inputs as a structured data part for exact control; a plain-text request is also accepted, from which only the state and the bill amount are read.

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.
