Solar Installations in the Overberg

The Overberg is a major grain, canola, sheep and dairy region, with fruit farms and packhouses in Grabouw and Elgin and growing commercial activity in Hermanus. Thermo Group designs and installs larger solar systems for farms, wineries, packhouses, commercial and industrial sites and developments across the region, with a focus on larger projects rather than small call-outs.

What farms and businesses here use power for

Packhouses and cold stores in Elgin, dairies and grain handling elsewhere, plus pumps, workshops and sheds. Rural supply can be weak in places, so protection and inverter sizing matter.

Regional conditions that affect your system

The Overberg is mild but windy, with cooler and wetter conditions in Elgin and good summer sun elsewhere. Strong wind makes mounting design and roof condition important.

Approval and compliance

A grid-tied system must be registered with the local municipality, or with Eskom where the property is supplied by Eskom, before it is switched on, and needs an electrical Certificate of Compliance. Requirements differ from one municipality to the next, so we confirm them at the start and handle the application and the certificate. Ask your accountant whether the Section 12B tax allowance applies to your business or farm.

How we work outside Cape Town

After you send a recent bill and a few details, we arrange a site visit, size the system around your actual loads and give you a written quote. We maintain the systems we install and larger farm and commercial arrays. Very small residential jobs in remote towns are better served by a local installer, and we will say so honestly.

Frequently asked questions

How windy is too windy for solar panels? Properly mounted systems handle strong wind, but design matters. We design to the local wind load and check roof structure before we install.

Do you install solar for farms in the Overberg? Yes. We design around pumps, cold rooms, cellars, dairies and sheds, and we handle registration and the certificate of compliance.
