§ 03 · Solar & storage

Quote a 20-year PPA in nine seconds, not nine days.

Allometry runs every PPA quote through 14 years of generation curves, your interconnect cost-to-serve, and live tax-equity assumptions — so the floor you offer the customer is the floor your finance team will sign.

A PPA, priced

14 inputs. One quote.
Defensible to your CFO.

Most solar dev teams quote on a spreadsheet that's six months stale and four assumptions deep. Allometry pulls live ITC, REC, generation curves, and interconnect costs into every quote — and shows the math.

Where it fits

Three solar segments. Same engine.

From rooftop C&I to distributed storage to community solar — the cost-to-serve and revenue stack are different, but the math is one shape.

§ 01 · C&I rooftop

Build PPAs that survive interconnect

Score every roof against IOU territory, structural class, and shading curves before reps quote. No more deals that die at engineering review.

§ 02 · Storage as a service

Price tolling against real wholesale

Co-located batteries are priced by tolling against day-ahead curves. Allometry runs that against your dispatch model and degradation schedule live.

§ 03 · Community solar

Subscriber economics, not just project

Subscribers churn. Bill credits drift. Allometry models the subscriber side of community solar against the project side, on the same quote.
