Solar project software that checks the numbers before the money moves.

Debt coverage, budgets and permits are checked under each country's rules and in each project's currency, so problems surface before a lender sees them. Built for emerging markets, with every party to a project working from one record.

No account needed. Every figure in it is illustrative sample data.

One project, five steps

This is the walkthrough we give. One commercial rooftop in Colombia, followed from listing to the investor's quarterly distribution. Each step is a screen in the app. A project in the United States runs on the same record, with its own underwriting file and permit steps.

  1. A developer lists the project

    Developer

    Site, system size and offtaker go in once. The project gets a construction plan with milestones and a payment schedule. If the developer's firm has an engineer on the platform, the engineer signs off before Nuentero sees it.

  2. Nuentero underwrites it

    Nuentero

    The project file collects what a lender checks before funding a site: the PPA, offtaker credit, roof rights, grid connection approval, yield study, EPC contract and the rest. Nuentero staff review the file and, once it is complete, move it to financing.

    Data room table for a sample site: the PPA, offtaker credit file, roof right of use, grid connection approval, energy yield study and EPC contract, each with what it proves, who issues it and its status.

  3. The fund calls capital

    Fund manager, investor

    The fund manager issues a capital call pro rata to commitments. When a USD investor pays a peso call, the receipt records the rate used, its date and its source.

  4. An installer builds it

    Installer, distributor

    Installers bid hours and rate on the open-projects board. The awarded installer gets a work order with scope, hours and rate fixed, and buys equipment from distributors at delivered cost, with freight and storage on their own lines.

  5. The investor sees it run

    Investor

    Once the site generates, the investor sees metered kWh per site each month and a distribution each quarter in USD, translated at the official rate on the payment date.

Who uses it

Six kinds of users work on the same record. Each sees the part that is theirs.

Each party keeps its own copy of the same project.

The developer has the specs, the installer has the work plan, the fund has the books, and the investor gets a quarterly PDF. Each copy is typed in again by hand, and a lender's question takes days to answer.

In Nuentero, each party works on its own part of one project record.

Sales CRMs stop tracking a project once financing is approved. Nuentero keeps tracking the money after that.

The platform runs in Colombia and the United States.

Each account chooses its markets when it signs up, and each record carries its own country and currency. The workflow is the same in both. This is what changes.

Important information

Nothing on this page is an offer to sell or a solicitation of an offer to buy any security. Interests in any fund are offered only to accredited investors, only through definitive offering documents, and only in jurisdictions where such an offer is lawful.

Nuentero Inc. is not a broker-dealer, investment adviser, or fiduciary, and does not provide investment, legal, tax, or accounting advice. Nuentero provides administration, reporting, and technology to funds managed by independent sponsors. Those sponsors manage the funds and make the investment decisions.

Investing in private funds involves risk, including loss of the entire amount invested. Interests are illiquid, have no public market, and may not be transferable. Solar assets depend on offtaker performance, grid interconnection, regulation, equipment, and weather.

Fund assets generate revenue in Colombian pesos while capital is subscribed and reported in US dollars. Currency movement can reduce or eliminate returns independent of how the assets perform.

Any projection, target, or model shown here or in fund materials is an estimate, not a promise. Actual results will differ. Past performance of any fund, asset, or sponsor does not indicate future results, and Nuentero makes no representation or warranty regarding investment returns.

Information on this page may include data from sponsors, offtakers, and other third parties that Nuentero has not independently verified, and may change without notice.
