Commercial and industrial rooftops,
engineered from the roof up.
Start with an address and the customer's bill. The roof comes back measured — planes with their pitch, orientation and area — you confirm what is really up there, and the platform lays out the modules and strings, simulates the production plane by plane, and prices the saving on that customer's own tariff. Out comes a proposal, the drawings behind it, and the paperwork the connection will need.
Agentic AI that gets clean energy engineered, financed and built
Built for the teams that win rooftop projects
One pass from an address to a document a customer can act on — with the engineering, the tariff and every assumption visible behind it.
C&I originators
You are chasing warehouses, malls, cold stores and factories, and most enquiries never justify a site visit. Every one of them can still get a proposal with a real roof, a real tariff and a stated export rule behind it — before anyone drives anywhere.
EPCs
Your engineers should be building, not redrawing roofs for offers that never close. The roof layout, the string plan, the behind-the-meter single-line diagram and the cable routes come out of the same geometry as the numbers, in PDF and CAD, with every assumption printed as an assumption.
Rooftop-PPA providers
Your offer is judged against the bill it replaces. Savings are worked out on the customer's own tariff — energy and demand charge apart — and capital, lease and power purchase are compared on the same production, the same tariff and the same export rule.
From an address to a proposal you can send
The C&I Rooftop AI Agents do this work with you — ask in plain language for a roof, a layout, the case for a battery, or the whole proposal. Every output states where its inputs came from, so the customer — or the customer's engineer — can check it.
The roof, with its provenance
Roof planes from aerial imagery, each with its pitch, orientation and area — or the mapped building outline where no measured data exists. Which of the two you are looking at is stated on the roof, in the proposal and on the drawings, never blended into one number.
A layout that respects the roof
Modules placed plane by plane with edge setbacks and walkways, obstacles and keep-out areas left clear, and strings sized against the inverter's voltage window at the site's own minimum temperature.
Production, hour by hour, plane by plane
A full year simulated for every plane at rooftop temperatures. A flush array on a hot metal deck does not run as cool as an open-rack field, and it is not modelled as though it does.
The customer's bill, not a tariff average
Savings are priced on the tariff that customer is actually on, with energy and demand charge kept apart, and the export rule that applies at that system size is named and cited rather than assumed.
A battery sized where it earns
Storage is sized against the monthly peak that sets the demand charge, and against generation that would otherwise leave the site below its value — not fitted to a round number of hours.
Capital, lease and power purchase, side by side
The same system priced three ways on the same production, the same tariff and the same export rule, so the customer compares structures rather than quotes.
Drawings, in PDF and CAD
Roof layout plan, string plan, behind-the-meter single-line diagram and cable route plan — rendered from the same geometry the numbers came from, each carrying its assumptions as assumptions.
The proposal, and the paperwork behind it
One document covering the roof and how it was measured, the layout and equipment, the production, the bill today and tomorrow, the three financing structures and what still has to be verified — with the connection paperwork checklist for that system size beside it.
Six steps, one pass
Nothing is designed on a roof the customer has not confirmed, and nothing is priced on a tariff they are not on.
- 01
Capture the roof
Type the address. Where imagery supports it, the roof comes back as planes with their pitch, orientation and area; where it does not, you get the mapped building outline and are told which one you have.
- 02
Confirm it
You correct what imagery cannot know — the plant room added last year, the skylight row, the bay the tenant will not release. The confirmed roof is what everything downstream is built on.
- 03
Design the system
Modules and strings fill the confirmed planes, keeping edge setbacks and walkways clear, and the inverters are sized against the strings rather than the other way round.
- 04
Price the bill
Production meets the customer's tariff: energy and demand charge are separated, the export rule for that system size is applied and named, and a battery is sized against the peak that sets the demand charge.
- 05
Draw it
The roof layout, the strings, the behind-the-meter single-line diagram and the cable routes render from the same geometry as the numbers, and export to PDF and CAD.
- 06
Send the proposal
One proposal document for the customer, and the connection paperwork checklist for that system size for you.
What it does not do
A rooftop offer is only useful if everyone knows which parts still need a person on site. These do.
It does not sign off your roof
Uplift, ballast and purlin loading are a structural engineer's opinion, and the platform does not offer one. Roof structure, wind speed, fire setbacks and switchboard capacity are listed as items to verify on site on every proposal.
It does not replace the site visit
Imagery is imagery. Roof condition, cable paths, shading that appeared after the photograph, the state of the main switchboard and exposure to theft and vandalism are confirmed by someone standing on the roof.
It does not fly a drone
Geometry comes from aerial imagery, from the mapped building outline, or from a drawing you supply. Photogrammetric capture is not part of the service.
It is not a qualified signature
Your customer can accept the offer online, and the record names who accepted it, when, from which verified email address, and which version of the offer. That is an acceptance with an audit trail — not a qualified electronic signature, and not the contract you sign afterwards.
It does not obtain the connection
The drawings are engineering documents and the checklist names the forms, studies and fees the utility will ask for. Submission, the stamp of a licensed engineer and the utility's own review stay with you.
