Solar revenue, financed and operated end-to-end

We fund the solar, bill the residents, and pay HOAs and build-to-rent operators every month.

Billing software makes you buy the array first. Installers hand you the operating headache. NOI does all of it — capital, install, metering, resident billing, collections, and your monthly payout — on one contract, with zero capex and no special assessment.

Project types

Every roof, canopy, and clubhouse is a revenue asset.

Rooftops, carports, and amenity buildings across garden-style multifamily, build-to-rent, and HOA communities. Same playbook every time: we fund it, build it, meter it, bill it, and wire you the margin.

Why NOI

Billing software won't buy your panels. Installers won't bill your residents.

The market is split in two: software vendors that meter and invoice — after you've already spent the capital — and installers that build the array and hand you the operating problem. NOI is the only stack that owns the whole chain, from the check that funds the roof to the deposit that hits your account.

No stitching together a lender, an EPC, a billing vendor, and a support desk. One agreement covers capital through payout.

Underwritten on your NOI, not your credit

We model the revenue the roof can produce and finance against it — so the program clears without touching your balance sheet.

Residents come out ahead

Enrollment holds because the savings are visible on the statement. Participation is what protects the revenue line.

The reposition

Most landlords think of solar as a cost to manage. We think of it as a line item to grow.

Own the roof.

You keep the asset and the agreement. We add the meter and the billing rail underneath it.

Own the revenue.

Solar income lands next to rent — one invoice to the tenant, one payout to you, every month.

Own the upside.

When local power prices rise, your revenue per unit rises with them. The roof keeps appreciating.

The mechanism

From rooftop to revenue, in four steps.

You own the building. We operate the revenue layer on top of it.

  1. 01
    Assess

    Send us a recent utility bill. We model production, tenant load, and local rates, then return a no-cost revenue projection in days.

  2. 02
    Install

    Our partner network handles permitting, installation, and interconnection. Financed or owned — we'll quote both side by side.

  3. 03
    Enroll

    Tenants get a magic-link invite. They see exactly what they save vs. the grid and enroll in autopay in under two minutes.

  4. 04
    Collect

    Tenants pay via ACH or card. Stripe Connect routes net revenue to your bank. You get a clean monthly statement and dashboard.

The economics

A 24-unit building can add ~$17.7K in annual NOI. With no capex.

Tenants pay less than they did to the utility. You collect the margin. NOI takes a small share for running the rail.

Repositioning

“Solar is the mechanism. NOI is the outcome.

Stop thinking about panels. Start thinking about revenue per unit.
