Electricity is the one input cost
you can actually fix.

Wages rise, diesel rises, the grid rises 8–9% a year by regulator decree. A solar system is capital you spend once, at a price you know today, for energy that never gets an annual increase. We engineer systems around that trade — and prove the return with live monitoring.

Your exposure

The escalation curve is not your friend.

NERSA has already approved increases through 2027: 8.76% for direct Eskom customers from April 2026, 9.01% for municipal customers from July 2026, and another 8.83% in April 2027. If your business spends R50,000 a month on electricity today, the approved increases alone add roughly R100,000 a year to your costs by 2027 — before you use a single extra kilowatt-hour.

Panel performance warranty. We design whole systems for a 15-year life and provision the shorter-lived parts.

And every outage is unbudgeted cost. Spoiled stock, idle staff, missed production, generators drinking diesel. Whether the cause is load shedding or a stolen cable, a correctly sized hybrid system turns "the power is off" into a non-event.

What we build

Sized from your load profile, not a brochure.

Grid-tied PV

Maximum-yield daytime generation for operations that run when the sun does. The fastest payback of any configuration we install — every kWh generated is a kWh not bought at escalating rates.

Hybrid PV + storage

Solar plus batteries for businesses that can't stop when the grid does. Critical loads ride through outages; storage shifts cheap solar into expensive evening hours.

Generator integration

Already running a genset? We integrate it as last-resort backup instead of first response — solar and batteries carry the load, diesel becomes the exception, not the habit.

Load management

Optional Solaire Intelligence orchestration moves flexible loads — pumping, heating, refrigeration cycles — into solar hours automatically, stretching the same array further.

ROI-first proposals

Every proposal states payback period, year-one saving and long-run net benefit in rands, against your actual tariff. If the numbers don't work, we'll tell you that too.

Accountable performance

Add Solaire Intelligence monitoring and you see generation, consumption and savings on a live dashboard — and so do we, which is why monitored systems stay healthy.

How the maths works

A payback number, not a sales pitch.

Every site is different, which is why we don't publish package prices. But the structure of every proposal is the same: what you pay, what you save in year one at your current tariff, and what the system nets you over its life as tariffs keep climbing.

Because approved escalation is running at 8–9% a year, a system's saving grows every year even if your consumption doesn't. Payback typically lands well inside the system's warranty period — after that, the electricity is effectively free.

And the capital doesn't have to come off your balance sheet. Through Investec's Recharge platform, a commercial system can be structured as a fixed monthly rental — energy cost savings from day one, opex instead of capex, subject to credit approval.

Bring us twelve months of bills and we'll build this table for your site, at your tariff, with current hardware pricing.

A real site, measured

St Katharine's Preparatory School, Parktown.

A two-plant campus installation running live on our monitoring platform. In the winter of 2026 the area suffered a three-week utility outage — and the hall plant, sized precisely to its measured load, ran straight through it. Days, nights, weekends: uninterrupted.

Expansion now in progress, sized from that measured data

Why this matters to you: we size from measured winter performance, not brochure yield. The school's next phase was designed on the plant's own logged data — and because the systems are monitored, problems are seen before they're felt. That's the discipline every Solaire commercial proposal inherits.

After the handover

The install is the start of the relationship, not the end.

Year one: watched, included

Twelve months of remote monitoring and technical support come standard with every installation, plus a scheduled on-site inspection at three to six months. We see faults before you feel them.

Compliant by specification

Commissioned and tested to engineering spec before handover, with a Certificate of Compliance issued in accordance with SANS 10142.

Warranties, handled for you

Panels carry 30-year performance warranties, inverters and batteries their own manufacturer terms — and we manage every warranty claim on your behalf, at no additional cost.

Board approval to switch-on

Typically 10–15 weeks end to end, including the municipal grid interconnection application — scheduled around your operation, not ours.

Next step

Twelve months of bills. One honest answer.

Send us your recent electricity accounts and we'll come back with a site-specific proposal: system, capital, year-one saving, payback — the numbers either work or they don't.
