How Solar Finance Origination Works in South Africa

Most solar deals do not stall on the technical design. They stall on the money. A client wants the system, the installer has the quote ready, and then everyone waits while finance is figured out one phone call at a time. Solar finance origination exists to close that gap.

This guide explains what origination is, how a deal moves from quote to funded, and where a platform like ArkFlow fits for installers and EPCs.

What is solar finance origination?

Solar finance origination is the process of turning a solar quote into a fundable deal and connecting it to a lender who will pay for it. It covers everything between "the client wants a system" and "the bank releases the first payment".

In practice that means packaging three things into one application: the client, the equipment being financed, and the supporting documents a lender needs to make a decision. Done well, the client applies once and reaches several possible funders instead of chasing each bank separately.

ArkFlow is a solar finance origination platform built for South Africa. It connects EPCs and installers to lenders through a single, guided application process, so the deal moves forward without the installer becoming a part-time finance broker.

Why does origination matter for installers?

Installers are good at solar, not at credit applications. When finance is handled deal by deal, three things happen: quotes go cold, clients drop off during paperwork, and the installer carries risk while waiting for an answer.

Origination matters because it does the following:

• Keeps the client engaged with a clear, step-by-step process instead of silence.
• Reaches multiple funding routes from one application, improving the odds of a yes.
• Frees the installer to sell and build rather than chase banks.

What are the funding routes for a packaged deal?

Once a deal is packaged, it can be funded through three routes:

• The client's own bank, where there is an existing relationship.
• The installer's own lenders, if they already have funding partners.
• The ArkFlow lender network, which adds specialist solar funders.

The major South African banks that can sit behind these routes include FNB, Absa, Standard Bank, Nedbank, Investec and Capitec. Having more than one route is the point: a single application can be tested against several funders so the client compares real offers rather than settling for the first one.

How does the ArkFlow deal flow work?

The process is built so the installer stays in control of the relationship while ArkFlow handles the finance plumbing. It runs in five clear stages:

1. Propose and accept. The installer presents an indicative proposal. The client accepts it to start the process. You can read more in the indicative proposal explained.
2. Onboard with lenders. ArkFlow onboards the installer with the relevant lenders so deals can be submitted.
3. Guided application. The client completes a step-by-step finance application online, with clear prompts for each document.
4. Prequalify and package. The deal is prequalified, KYC-checked and packaged into the format the bank expects.
5. Offers and first payment. Offers come through, the client selects one, a contract is drafted, and the first milestone payment is released.

Throughout, the client-facing pages carry the installer's brand, not ArkFlow's. White-label is standard at no extra cost, covered in white-label solar finance.

What can actually be financed?

ArkFlow finances the equipment, not general business costs. The qualifying categories are:

• Solar PV systems.
• Batteries and energy storage.
• Power quality equipment.
• Generators.
• Water equipment, including treatment and supply.

The structure depends on whether the client wants to own the asset or pay for the output. Asset Finance runs 3 to 7 years, Rent-to-Own 5 to 15 years, and a PPA 10 to 20 years. Each is compared in detail in solar finance structures compared.

What does origination cost?

ArkFlow's sales side is free for installers, channel partners, brokers and lenders: leads, proposals and the client finance application cost nothing. There is no card required.

The platform adds 1% of capex to the bill of quantities where a deal funds through its lender panel. Installers add that 1% to their bill of quantities, and lenders pay 1% commission on capex. It is billed in milestones as the bank releases funds, for example on an 80/20 or 60/30/10 schedule, invoiced pro-rata at each release. The full mechanics are in the 1% success fee explained.

Frequently asked questions

What is solar finance origination?

It is the process of turning a solar quote into a fundable deal and matching it to a lender. The client, the equipment and the documents are packaged into one application, then routed to banks or specialist lenders so the client can compare offers and select one.

Do installers pay to use ArkFlow?

No. ArkFlow's owner account is free forever for installers, channel partners, brokers and lenders, with no card required. Additional seats and the Engineering Studio are paid. ArkFlow adds 1% of capex to the bill of quantities where a deal funds through its lender panel, billed as the bank releases funds.

Which banks can fund a solar deal?

A packaged deal can be routed to the client's own bank, the installer's own lenders, or the ArkFlow lender network. South African banks that can sit behind these routes include FNB, Absa, Standard Bank, Nedbank, Investec and Capitec.

How long does the process take?

It varies by lender and deal size, because the lender does the formal underwriting. A guided application with documents ready up front moves faster than a deal where paperwork is collected piecemeal. Indicative figures shown during the process are indicative only and not a credit offer.
