Screen every asset. Pursue the right ones.
Most feasibility lives in expired PDFs somewhere in a file cabinet. You never know know which properties to evaluate. Lumen starts with your whole book. The Lux Engine fuses data across property ownership, imagery, local utility rate data, building use, policy, and comparable market transactions — then ranks every asset by revenue potential before your team lifts a finger.
Prioritize
Portfolio-wide scoring from a single upload
Enter an address or your entire rent roll. Get instant feasibility scores covering roof viability, system size potential, and estimated annual revenue — no site visits, no vendor pitches.
Qualify
Your actual energy data, not our estimates
Upload utility bills in any format, any tariff, any provider. Our AI builds a precise hourly usage profile — the granularity required for investment-grade models, not back-of-napkin projections.
Configure
Modeled for your capital structure, not ours
System configurations generated automatically across solar, battery, and EV charging — with full financial models for PPA, rooftop lease, CPACE, or self-finance. We optimize for your returns.

[Marketplace — How the bid process works]
A competitive process built in your favor.
Lumen runs a structured, blind competitive bid among pre-vetted solar developers. They compete on lease rate, contract terms, and execution record. You see every offer side by side — with our analysis layered on top.
Blind competitive bidding
Developers don't see each other's offers. You get their best number, not their opening number.
Side-by-side bid analysis
Lease rate, IRR, contract length, escalators, counterparty risk — all normalized for real comparison.
Structure-agnostic selection
PPA, rooftop lease, CPACE, self-finance — the right structure for each asset, not the one we prefer.
[Execution]
From signed term sheet to first lease payment
Once you've selected a developer, Lumen becomes your project manager — coordinating permitting, construction milestones, and utility interconnection so your team stays focused on the portfolio, not the project.
Term sheet executed
Structural engineering sign-off
Construction underway
System energized
What we manage:
Utility interconnection
Permitting coordination
Tenant billing & ESG reporting
A partner. That's the whole difference.
Solar vendors sell you their product. Lumen runs a process that makes vendors compete for your business, then manages the deal to close on your behalf. We're paid when you win — which means our job is to maximize your rooftop revenue, full stop.
