The forecast is free. Pay once to go deep. Never pay through your installer.
The free forecast is the same engine that powers everything paid — paid adds depth, not accuracy. One credit pack permanently unlocks the financing workshop and deposits proposal-audit credits. No subscription, no lead-gen, no installer commissions.

Credit pack
one-timeA purchase does two things: it permanently unlocks the full forecast depth (account-wide, it never re-locks), and it deposits audit credits you spend on installer-proposal audits.
- Deep financing — loan / lease / PPA, real $/W slider, loan-vs-lease-vs-cash
- Tornado sensitivity on every assumption
- Workshop knobs — push the model past the defaults
- Battery hourly dispatch (8,760-hour, NEM 3.0 + TOU arbitrage)
- Multi-array — model every roof face independently
- Proposal audits — upload an installer PDF → extraction + variance + fair-market radar
Unlock the workshop + one audit.
$19 — about one month of Claude — for a $30k decision. Permanently unlocks the full forecast depth and deposits one proposal-audit credit.

Most homeowners collect 2–3 bids. The 3-pack runs each installer proposal through the same model and shows which bid actually wins on 25-year NPV.

Notify meDistribution of outcomes, not investment advice. No installer affiliations, no lead-gen, no kickbacks. The moat is real-data grounding — 1.5M LBL installs, URDB tariffs, NSRDB irradiance, pvlib physics — not an LLM guessing at $/W. Read the full methodology before committing.
