Swellendam and its surrounds have dairy, grain and livestock farms, along with tourism businesses along the Breede River valley. We install solar for farms, wineries, packhouses, commercial and industrial sites and developments around Swellendam, with a focus on larger systems rather than small call-outs. Tell us your monthly electricity bill and the roof or ground space available, and we will tell you quickly whether solar makes sense and what a system could look like.

Free solar quotes, no obligation. Installation and City registration handled for you. Qualified from 2007.
Solar for dairy, grain and livestock farms in Swellendam
Dairy parlours run milking equipment, milk cooling and water heating every day, often twice a day, which gives solar a steady, predictable load to work with. Grain farms and tourism businesses add further daytime demand. We design around your milking and cooling schedule.
What we install around Swellendam
- Rooftop systems on dairy buildings, sheds and barns.
- Solar for milk cooling and water heating.
- Systems for farm workshops and tourism properties.
- Battery backup and hybrid systems that keep critical loads running through load shedding and local outages.
- Grid-tied systems designed around your tariff, with the paperwork handled for you.
Local conditions that affect your system
Swellendam has warm summers and mild winters, with good sun for most of the year. Hot afternoons are when cooling loads peak, which lines up with solar output. Wind and occasional hail should be considered in mounting design.
Approval with Swellendam Municipality
A grid-tied system has to be registered with the local municipality before it is switched on, and it needs an electrical Certificate of Compliance. Requirements and fees differ between municipalities, so we confirm them with Swellendam Municipality at the start of the project and handle the application and the certificate. If you farm or run a business, ask your accountant whether the Section 12B tax allowance for solar applies to you.
Maintenance and fault finding
Larger systems need looking after. For the systems we install, and for larger farm and commercial arrays, we offer maintenance plans and fault finding so that cleaning, inverter checks and battery health do not get forgotten. See our solar maintenance service.
How we work outside Cape Town
We travel for larger projects. After you send your bill and a few details, we arrange a site visit, size the system around your actual use, and give you a written quote that shows what is included and what the payback assumptions are. Our focus is farms, businesses and developments, so very small residential jobs in Swellendam are better served by a local installer.
Frequently asked questions
Is solar worth it for a farm or business in Swellendam? For dairies and farms with daily cooling and pumping, yes. We base the model on your own bills and milking pattern.
Can solar work for a dairy? Yes. Milk cooling, vacuum pumps and water heating are daily loads, and solar can cover a large share of the daytime portion. Batteries can help with the morning and evening milking peaks.
Do you handle registration with Swellendam Municipality? Yes. We submit the application, arrange the electrical Certificate of Compliance and tell you what to expect before the system is switched on.

⭐⭐⭐⭐⭐ 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! 👏Posted on Google![]()

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. 💡⚡Posted on Google![]()

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.Posted on Google![]()

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.

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.
