☀️ Powering one of Cape Town’s most spectacular coastal locations!

Surrounded by mountains, ocean views and the natural beauty of Llandudno, this impressive GreenSun installation combines premium solar generation with serious battery storage.

The system includes:

⚡ 40.25 kWp of solar power
🔋 108.48 kWh of Sigenergy battery storage
🔌 2 × 20 kW Sigenergy three-phase inverters
☀️ 49 × 665 W and 15 × 510 W AIKO solar panels

Based on the installed solar capacity, the system could produce approximately 60,000 kWh of clean energy per year—an annual average of around 164 kWh per day. Actual production will vary depending on the seasons, weather, roof orientation and household consumption.

The high-output AIKO panels maximise the available roof space, while the modular Sigenergy system provides intelligent energy management and substantial battery capacity for use after sunset.

A beautiful location deserves an energy system designed to match it.

Designed and delivered by GreenSun Renewable Energy. 🌿⚡

Sneak peek from yesterday at The Galleria, Sandton. Herholdt's Group Summit 2026, and Greensun Solar Energy Solutions was invited in.

Gareth Cliff hosted this amazing event. The masterclass with Heine Herholdt and Vusi Thembekwayo was the part everyone will be talking about, and Sigenergy launched SigenStor Neo to the SA market while we were in the room.

Smart Port for third party inverters, generators and EV chargers. Backup Port for outages. Zero millisecond switchover.Up to six stacked battery modules, so the system grows when the house does.

Rooms like this are where you find out what is actually coming next… 🌍Africa’s energy future is looking bright..

More to come from the day.

“A solid company, that know their product, and after sales service that goes beyond expectation.”

That client review landed 30 minutes after we switched his upgraded system on.

Pieter has been a client of ours for years. This round we added 10 x 665W Aiko panels and a Freedom Won Lite 60/48 battery to his existing Victron setup: 21.3kWp of panels now, 60kWh of storage, behind two 10kVA Quattros.

Same client, bigger system, same standard of work.

“You should all be very proud of the company you have created,” Nick van Wyk wrote, after years as a client and a fair amount of contact with the guys who look after his system.

Selling a solar system takes an afternoon. Keeping a house running quietly on it for a decade, through the winters and the odd fault and whatever the grid does next, is the actual work. Jacques and his service team carry that part, and it doesn’t get posted about much.Long-term is the only review that means anything in this business. 15 years, 4,120 installations, 4.8 on Google, and clients who are still with us.

Sungrow Southern Africa visited GreenSun Renewable Energy and revealed all the latest in solar innovation. Liquid-cooled C&I storage, the PowerKeeper modular battery, the new hybrid inverters, all of it open and standing in front of us with the people who build it answering questions.

What that hardware means for a commercial client is the part worth paying attention to. Wheeling. Peak shaving. Demand control. Virtual power plants. And this year Sungrow added EV charging to the agenda, which tells you where South African commercial energy is heading.

Thanks to the Sungrow team for amazing products you have developed and thank you to Herholdt's Group for supplying us with only the best.

Up to R1,700 off your monthly bill. On City of Cape Town rates, that’s what this system takes off a home’s electricity spend, from month one.

One sleek tower does the work: SigenNeo 6.0kW inverter, 6.0kWh battery, and EV-charging-ready. Six Aiko Neostar 535W panels on the roof, backed by a 30-year performance warranty.

When the grid drops, switchover is instant (0ms), so you won’t even see the lights flicker.

Fully installed from R103,546 incl VAT, with your COC and SSEG registration handled by our ECSA-registered team for total peace of mind. T&C’s Apply*

Installation Story | 5 Mountain Lodge & Spa

Greensun Renewable Energy completed this farm installation in Wellington, Western Cape, in 2025.

The system includes 3 × Quattro 15 kVA inverter/chargers, 2 × Fronius inverters, 1 × SmartSolar MPPT 450/200 and 28 × BYD LV5.0 batteries.

The installation supplies the property’s cottages, pumps and horse stables, helping the farm operate largely off-grid during summer and maintain power through frequent grid outages.

The key result: dependable power for the farm and greater independence from Eskom.

AC coupling was used to support the site’s high daytime consumption while reducing the cost and labour associated with longer solar array strings.

17:36 in Welgelegen yesterday, Cape Town. Grid: 0 kW. Battery: 99%, with 26.9 kWh still in the tank for the night ahead. The solar system was running the whole show on its own.

We put 13.3 kWp of AIKO Energy panels on that roof, a Sigen 12kW hybrid inverter and 27kWh of SigenStor storage all supplied by Herholdt's Group . It has been in self-consumption mode since day one and he has barely touched the grid since.

The timing helps him. Eskom went up 8.76% in April and municipal customers 9.01% in July, while inflation sat at 3.5%. His rate is not going anywhere.

Fifteen years and 4,120 projects in, this is still the best part of the job: someone opening an app, seeing a zero, and being pleased enough to tell us about it.

Most farms don’t have an energy problem. They have a timing problem.

Panels are the easy part. The expensive part is that irrigation pumps and a hatchery pull hardest at the hours Eskom charges the most. Winter peak is R8.17 per kWh today, escalating at about 9% a year.

A farm we work with in Heidelberg, Western Cape grows canola, wheat, barley, lucerne and maize, most of it feeding their own ostriches. Water on the lands, and heat in the breeding sheds. Neither is optional.

So we built for timing, not only volume: 133.9 kWp of Aiko modules into a 110 kW Sigenergy hybrid on the farm, and 108 kWh of Sigenergy storage at the homestead so cheap energy gets banked and spent during peak. Their original 65 kWp GoodWe system stayed exactly where it was, integrated and on the same portal.

Roughly 199 kWp and 230 kW of inverter capacity across the property, built in phases as the operation grew.

If you’re irrigating through peak and still fully on Eskom, that’s not an energy problem. It’s a cash-flow one.
