Robertson lies deep in the Breede River Valley, with hot, dry summers, clear skies and very strong sunshine. The valley’s wine, fruit and tourism businesses use a lot of power during the day — for irrigation, cellar cooling, cold storage and hospitality — which makes solar a natural fit.

We work with households in town, guesthouses and lifestyle properties, and working farms and wineries. Every project begins with a site assessment, and we design around your real usage and backup needs. SunSynk inverters with Hubble lithium batteries are among the systems we install most often, alongside larger three-phase systems for farms and commercial sites.

Solar For The Robertson Wine Valley

🍇

Wineries & Cellars

Cellar cooling, pumps and bottling or processing loads designed as single- or three-phase systems with the right protection.

🏨

Guesthouses & Tourism

Solar and backup that keeps guests comfortable and bookings running during outages, with lower running costs in peak season.

🌡️

Designed For Valley Heat

Cool, ventilated equipment placement and panel mounting that allows airflow, for reliable summer performance.

Wine Farms And Agricultural Businesses

The Robertson Wine Valley is known for its wineries and fruit farms. Harvest and summer are the busiest times for cellar cooling, irrigation and processing — the same months solar production peaks. We assess each load, including motor start-up currents from pumps and compressors, and design systems that make a real difference to operating costs. Where buildings are spread across a farm, we plan cabling and protection to deliver power safely and efficiently. Farms supplied directly by Eskom follow Eskom’s process, which we manage.

Guesthouses, Restaurants And Tourism

Robertson and the Route 62 corridor attract steady tourism, and outages are bad for business. For guesthouses, restaurants and venues, we design systems that keep lights, Wi-Fi, refrigeration, card machines and key equipment running, while cutting daytime costs. We configure battery reserves so essentials stay powered even when guests are using power heavily.

Homes In Robertson

For households, a hybrid system reduces electricity bills and keeps essentials running during outages. We check the existing electrical installation before connecting the inverter, and as registered electricians we correct any issues that would prevent certification.

Designed For The Climate

Summer temperatures in the valley can be very high. We place inverters and batteries in cool, ventilated locations, mount panels with airflow beneath them and specify equipment suited to the conditions. We also account for colder winter nights when sizing batteries for evening use.

Built For Robertson Conditions — And Maintained Afterwards

A solar system in Robertson has to cope with very hot summers, dust and heavy seasonal farm loads. We build that into the installation from day one, and we stay involved afterwards.

After your installation we can service the system, check the panels, mounting, cabling and connections, update inverter settings and investigate any drop in performance. If you already have a system installed by another company that isn’t performing, we can inspect it, find the fault and repair it. See our Solar Maintenance and Solar Repairs & Fault Finding pages.

SSEG Registration With Langeberg Municipality

Any solar or battery system connected to your property’s electrical supply in Robertson must be installed by a registered electrician and certified. If the system is grid-tied or hybrid, it must also be registered as a Small-Scale Embedded Generator (SSEG) with Langeberg Municipality before it is used — or with Eskom if your property is supplied directly by Eskom, as many farms are.

Thermo Group handles this for you: we use inverters on the approved list, complete the application and supporting documents, issue the Solar Certificate of Compliance and electrical COC, and deal with any follow-up questions from the municipality. Getting this right protects your insurance, avoids penalties and makes a future property sale much simpler.

Is solar a good investment for a wine farm in Robertson?

Often, yes. Summer cellar cooling, irrigation and processing loads happen during peak solar hours. We assess your loads and give you a clear picture of costs and savings before you commit.


Can you keep my guesthouse running during outages?

Yes. We design backup systems for lights, Wi-Fi, refrigeration and key equipment, with reserves set so essentials stay on.


Do you register systems with Langeberg Municipality?

Yes. We handle the SSEG application and certification with Langeberg Municipality, or Eskom where the property is supplied directly.


Will the heat damage my inverter or batteries?

Not if they are installed correctly. We use cool, ventilated locations and equipment rated for the conditions.


Do you handle SSEG registration with Langeberg Municipality?

Yes. We prepare and submit the SSEG application, supply the inverter certificates and wiring diagrams, and issue the Solar Certificate of Compliance and electrical COC. If your property is supplied directly by Eskom, we follow Eskom’s process instead.


How much does a solar installation cost in Robertson?

It depends on your usage, what you want to back up, battery size and your roof. A small backup system for essentials costs far less than a system that runs the whole property. We assess your property and electricity use first, then give you a detailed, itemised quote rather than a generic estimate.

⭐⭐⭐⭐⭐ Excellent Service from Thermo Group! I had a wonderful experience with Thermo Group when I needed electrical issues fixed at my home. From the very beginning, the service was excellent. Nikita, the office administrator who assisted me with booking the job, was incredibly helpful, friendly and professional. She made the booking process smooth and effortless. Warwick, the technician who attended to the electrical issues, was equally impressive. He was professional, knowledgeable and efficient, and I truly appreciated the service he provided. It's refreshing to deal with a company that values its customers and delivers such great service from the office right through to the technical team. A big thank you to Nikita, Warwick and the entire Thermo Group team! I would highly recommend their services to anyone looking for reliable and professional assistance. Keep up the excellent work! 👏

I would like to compliment Warwick and the Thermoelectrics team for their excellent service! ⭐👏 Warwick came out over the weekend to attend to my lights that were not working, and I was truly impressed with how helpful, efficient and professional he and his team were. It is not often that you come across a team that is so willing to assist, even over weekends. Thank you, Warwick, and the team, for going the extra mile and ensuring that the problem was attended to. Your dedication and excellent service are truly appreciated! I would definitely recommend Thermoelectrics Compliance, Solar, Electrical & Plumbing to anyone looking for reliable and professional service. 💡⚡

Thermo Group delivered exceptional service from start to finish. From my first contact with Nikita who listened to me & responded urgently, to the electricians Alfred and Phato who arrived promptly, quickly found the problem and returned over the weekend to make repairs at short notice and even waited without complaint for 2 hours for the municipal contractor, to Warwick who was available around the clock and went above and beyond to check in with me and to get the City to restore my power after it simply closed my case after 6 hours. The team’s professionalism, clear communication and follow-through, genuine care and support are rare. I highly recommend Thema Group.

Alfred and Yusuf were absolutely amazing checking and redoing our electrics. Alfred made the effort to keep us in the loop at all times and went above and beyond to resolve issues. The team were considerate of us working from home but still very quick and efficient. I would not hesitate to recommend them.

On 24 September 2026 Russel and his team (Ebrahim, Michael and Alfred) visited us and went through the various areas of their expertise. We found them to be very pleasant and knowledgeable in their respective fields. It was a real pleasure having them carry out the COC.
