NOI (Net Operating Income) Growth Platform

Your roof is a
revenue line.

NOI installs rooftop solar on your rental, meters tenant consumption, and bills them on your behalf. You collect a new monthly check — without writing one first.

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.

From utility bill to revenue estimate, in under a minute.

Watch a landlord turn a single PDF into a no-capex revenue projection — live in the NOI portal.

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.
