API FAQ

Which teams should start with this API?

Installer sales teams, loan origination teams, and partner platforms that need fast, transparent homeowner estimates.

Can we use API outputs in customer proposals?

Yes. You can convert simulation responses into PDF and XLSX reports for advisor-led or self-serve customer journeys.

Are the results final engineering values?

No. Outputs are planning-level estimates and should be finalized by licensed site assessment and interconnection review.
