Pricing

The forecast is free. Pay once to go deep.

The free forecast is the same engine that powers everything paid — paid adds depth, not accuracy. One credit pack unlocks the financing workshop and deposits proposal-audit credits. No subscription, no lead-gen, no installer commissions.

Credit pack

one-time

A purchase does two things: it permanently unlocks the full forecast depth, account-wide, and deposits audit credits — one per proposal.

what the unlock adds
  • Financing in depth — loan, lease, and power-purchase agreement compared, a price-per-watt slider, and every assumption ranked by impact
  • Battery charging planned hour by hour, and every roof face modeled on its own
  • Proposal audits — one credit per installer PDF you run
