SOL · 01 · Commercial & industrial solar

Your power bill rises every year. Your solar plant doesn't.

Lock the cost. Own the asset. Megawatt-scale solar, engineered and run by one South African team. We read your real bill, build the plant that cuts it, then track every rand it gives back. Eskom's (the national utility) direct tariffs rose 12.74% in 2025 and about 8.76% in 2026 — above inflation, again. Every year you don't generate, the bill compounds.

SOL · 02 · Not a green gesture

Solar isn't an environmental choice. It's a financial one.

Power is one of your biggest controllable costs. It's the only one guaranteed to rise above inflation, forever. Solar turns that rising rental into a fixed, owned asset on your own roof. The carbon saving is real. It's just not why the numbers work.

SOL · 05 · One team, end to end

One team designs it, builds it, and still answers the phone in year eight.

We're an EPC (engineer–procure–construct) that operates — not an installer that invoices and disappears. Our own engineers deliver flagship projects. We scale through a vetted partner network, but we keep the relationship and the engineering in-house. If a plant underperforms, we catch it and own it.

One team, end to end · we engineer, build and operate C&I solar — and still answer the phone in year eight
01

In-house engineering

Our own engineers deliver the flagship builds — design, structural and electrical kept under one roof.

02

One point of accountability

Vetted partners for scale, but the relationship and the responsibility stay with us. No finger-pointing.

03

Conservative yield modelling

We model to a conservative case, not best-case marketing. The forecast is the one we hold to.

04

Watched after handover

Every plant is monitored continuously through EnergyCloud — so drift is caught, not discovered.

SOL · 06 · The part everyone makes your problem

The panels are the easy part. The paperwork is where projects die.

Grid-tie approval. SSEG registration (the municipal sign-off to connect your own generation). Structural sign-off. This is where most C&I solar stalls for months. We run it as a managed process with a clear timeline, so you're not chasing a municipality. Sub-1MW for your own use needs no NERSA generation licence — but the paperwork still kills projects. We own it.

SOL · 08 · Because we're not tied to a funder

Every competitor sells the funding model that suits them. We sell the one that suits your balance sheet.

PPA-only providers push PPAs because that's their book. We're finance-agnostic. The structure follows your needs, not ours.

"Won't this lock me in?"

Terms are flexible. Exits and buyouts exist, and ownership is always on the menu.

"Do I lose the upside?"

You can own it and keep the full benefit — the upside stays yours.

"What if I sell the building?"

Contracts are portable. The plant and its terms move with the deal.

"Is my site even suitable?"

The bill upload tells you before you spend a cent.

"What's your catch?"

Equipment margin, an optional software subscription, and flagship project margin — stated plainly. No hidden take.

SOL · 09 · The quote is easy. The decade is hard.

Anyone can install panels. Few will still be accountable for them in year ten.

NERSA-registered. B-BBEE Level 2. Durban-based. One team across design, build and operations. We make money when your plant performs over its life — so our incentives match yours for the full asset life, not just to signing.

SOL · 10 · Where this leads

This isn't just cheaper power. It's your first move into a market that's finally opening.

SAWEM — the new national wholesale electricity market — went live in April 2026, ending Eskom's single-buyer monopoly. CONFIRM SAWEM go-live at publish The law now recognises private trading and virtual wheeling (moving power across the grid to another site). The plant you build today becomes an asset you can eventually trade from.

Wheeling, PPAs and trading are on the EnergyCloud roadmap (Soon). You're not just cutting a cost. You're buying a position before the market opens — generation capacity, metered and monitored, ready to participate.
