Wellington has some of the best solar conditions near Cape Town: hot, dry summers, clear skies and long days during the growing season. That is exactly when farms and agricultural businesses use the most power for irrigation, cooling and processing, which makes solar a strong financial fit here.
We install for households in town, lifestyle smallholdings and working farms. Every system starts with a site assessment of your roof or ground space, usage and backup needs. We regularly install SunSynk inverters with Hubble lithium batteries, and design larger three-phase systems where needed.

Solar Designed For Wellington Properties
Wine, Fruit & Farming
Systems for irrigation pumps, cold rooms, cellars and packing sheds, where daytime demand matches solar production.
Built For Boland Heat
Ventilated inverter placement, battery locations out of direct sun and panel spacing that helps them run cooler.
Homes & Smallholdings
Hybrid systems that cut bills and keep lights, Wi-Fi, fridges and pumps running during outages.
Homes And Smallholdings In Wellington
Wellington homes range from older houses near the town centre to newer suburbs and smallholdings on the edge of town. For households, the aim is usually lower electricity bills and backup power for essentials. Older properties sometimes need distribution board or earthing upgrades before a hybrid inverter can be added, and as registered electricians we check and correct this as part of the installation so the whole system can be certified.
Farms, Wine And Fruit Producers
The Wellington valley is surrounded by vineyards and fruit farms. These businesses have heavy daytime loads in summer — irrigation and borehole pumps, cold rooms, cellar cooling and packing equipment — which lines up well with peak solar production. We assess each load, including motor start-up currents, and design single- or three-phase systems with the right protection. Farms supplied directly by Eskom follow Eskom’s process, which we manage.
Designing For Summer Heat
Summer temperatures in Wellington can be very high. Panels lose a little efficiency in the heat, and inverters and lithium batteries perform best within their temperature ratings. We place equipment in cooler, ventilated positions, mount panels with airflow beneath them, and specify equipment rated for the conditions. The result is a system that performs well in January, not just in spring.
Commercial Solar
Shops, workshops, guesthouses and other businesses in Wellington can reduce daytime electricity costs significantly with rooftop solar. We design around your consumption data and roof space, and handle the compliance and registration paperwork.
Built For Wellington Conditions — And Maintained Afterwards
A solar system in Wellington has to cope with intense summer heat, farm dust and heavy daytime 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 Drakenstein Municipality
Any solar or battery system connected to your property’s electrical supply in Wellington 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 Drakenstein 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.

Book Your Wellington Solar Assessment
Fill in your details below and tell us a little about your property in Wellington — roughly what you use each month, what you want to keep running during outages, and whether it is a full-time home, holiday home, farm or business. We will contact you to arrange a site assessment and a detailed quote.
Is solar worth it for a farm in Wellington?
Usually, yes. Farms have high daytime loads in summer from pumps, cooling and processing, which coincide with peak solar production. We assess your loads and give you a clear financial picture before you commit.
Can you install solar for a wine cellar or cold room?
Yes. We design systems for cellars, cold rooms and packing sheds, including three-phase systems, sized for their running and start-up loads.
Does the heat in Wellington affect batteries?
Lithium batteries perform best within their rated temperatures. We install them in cool, ventilated locations and out of direct sun to protect performance and lifespan.
Do you also do compliance certificates in Wellington?
Yes. We issue Solar and Electrical Certificates of Compliance and can inspect and certify the rest of the property’s installation at the same time.
Do you handle SSEG registration with Drakenstein 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 Wellington?
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.
