Your power bill keeps rising. Solar stops it.
We build solar plants for farms, mines, factories and commercial property. You stop renting power from Eskom and start making your own, at a price that does not go up every year. One South African team designs it, builds it and runs it.
Power costs rise. Solar fixes the price.
Electricity is a cost you rent and can never control. Solar turns it into an asset you own. Your power price stops moving, and the money you were losing to increases stays in the business.
Move three sliders. Get a rough payback.
Tell us what you spend, what your site looks like and where you are. You get the plant size that fits and roughly how fast it pays back. A ballpark to start with, not a quote.
Indicative only — actual yield depends on site, shading, tariff and load. Assumes a plant built to power your own site, replacing grid energy at a blended rate.
Send your bill. We’ll do the maths.
Send one recent bill and we read it for you. We check your tariff, work out what your roof could make, and show the saving in Rands. Free, and nobody phones you unless you ask.
One team builds it. One team runs it.
We design, build and operate the plant ourselves. One number to call, and nobody to blame but us. We keep watching it after handover, so a drop in output is something we spot — not something you discover.
In-house engineering
Our own engineers deliver the flagship builds — design, structural and electrical kept under one roof.
One point of accountability
Vetted partners for scale, but the relationship and the responsibility stay with us. No finger-pointing.
Conservative yield modelling
We model to a conservative case, not best-case marketing. The forecast is the one we hold to.
Watched after handover
Every plant is monitored continuously through EnergyCloud — so drift is caught, not discovered.
Paperwork stops most projects. We handle it.
Getting permission to connect is where most solar projects stall. We deal with the municipality, the registration and the structural sign-off for you, on a timeline we give you up front. You do not chase anyone.

About 30% off the yearly bill.
This is a worked example of a typical job, not a real customer.* It shows where the money comes back: your own power replaces expensive grid power, your peak draw drops, and we move you onto the right tariff.
Five ways to pay. You pick.
Most solar companies offer one way to pay, because that is the only deal they have. We are not tied to a bank or a funder. Buy it, rent it, fund it or pay per unit — whatever suits your books.
"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.
We’re still here in year ten.
Quoting a plant is easy. Keeping one running for its whole life is not. We earn while your plant performs, so we stay involved long after the invoice is paid. Registered with NERSA, B-BBEE Level 2, based in Durban.
