🍷Kanonkop has made some of South Africa’s most celebrated reds for decades. Now their cellar runs on the sun.

We’ve just commissioned a 148.59 kWp expansion at the Stellenbosch estate: 234 Longi 635W panels feeding a Sungrow 125kW grid-tied inverter, integrated cleanly with the solar and battery storage they already had on site.

We also handled the generator integration and set up the battery for energy arbitrage, charging it when power is cheap and drawing on it when grid rates peak, so every kilowatt works as hard as it can.

The result is lower electricity costs every month, and stable power through harvest, when cold rooms and processing equipment cannot afford to skip a beat.

They also signed onto our Operations and Maintenance plan, so the system stays monitored live and serviced year round. No guesswork. Just power that performs.

Reliable, affordable energy, done right.

Most CFOs still treat electricity as a fixed cost.

It hasn’t been one for years.

+8.76% Eskom in April. +R5.27/L diesel in May. +9.01% municipal in July. Three increases. One quarter.

A 10-year GreenSun PPA locks you at R2.30/kWh. 4.67× cheaper than running a genset. 80% cheaper than winter peak.

The review you want is the one that lands months after commissioning, when the novelty has worn off and the system is just doing its job.

Raniel Koegelenberg, Pick n Pay Riebeek West: “The solar system is performing as expected, all work was carried out to a high standard and in compliance with relevant regulations. We would confidently recommend GreenSun Solar to any organisation seeking a reliable and experienced solar energy partner.”

Behind that review: 233kWp of Longi solar, 340kWh of Sigenergy storage, integrated with the site’s existing generator. A 4.5-year payback under Section 12B. But the spec sheet isn’t really the story. The story is a retail operator who can stop thinking about power and get back to running his store.

That’s what energy done right actually looks like.

Here’s what unplanned downtime costs a cable manufacturer: ruined batches, scrap metal losses, missed deadlines, and a diesel bill from a backup generator that never seems to end.

South Ocean Electric Wire Co doesn’t have that problem anymore.

Just over a year since we completed what became the world’s largest Sigenergy containerised solar installation, together with Herholdt’s Group.

4.2MWh of storage across 4 containers. 0ms changeover. Their production floor hasn’t skipped a beat.

No grid anxiety. No generator costs. No scrap losses. Just clean power and the kind of peace of mind that shows up on the bottom line.

If rising energy costs are eating into your margins, this is worth a conversation.

Today is Earth Day, and the sun is doing what it always does: rising, shining, and giving energy for free.

The question is, are you making the most of it?

Every solar system we install is our way of saying thank you to this planet. Cleaner air, lower bills, and energy that doesn’t cost the earth.

Happy Earth Day from the GreenSun family. 🌍☀️

☀️Hermanus gets close to 2,800 hours of sun a year. This homeowner at Arabella decided to do something about that.

We recently completed this residential installation at Arabella Country Estate, and it’s a solid example of what a properly engineered home energy system looks like in 2026.

☀️ 18 x Aiko Neostar 510W panels (9.18kWp)
⚡ Victron Multiplus II 10kVA inverter
🔋 20kWh BYD LV5.0 battery storage
📊 Victron Cerbo GX monitoring

Aiko panels aren’t on every roof in the Western Cape. They’re specified when someone actually cares about long-term yield and system performance, not just the number on a quote.

Engineered for performance. Built for the long run. That’s energy done right. 💡
