The Klein Karoo and Cederberg have some of the strongest sun in the Western Cape, with citrus packhouses, wine cellars, ostrich and lucerne farms and irrigated agriculture. 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
Irrigation pumps, packhouses and cold rooms, cellars, dairies, lodges and guest farms. High solar radiation and large daytime loads make solar especially effective.
Regional conditions that affect your system
Summers are very hot with strong sun and low rainfall, and winters are cold on clear nights. Heat reduces panel efficiency and stresses batteries and inverters, so ventilation and equipment choice matter. Dust and occasional hail should be part of the design.
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
Does extreme heat make solar less effective? Heat reduces efficiency a little, but strong sun more than makes up for it. We choose equipment rated for hot conditions and design for ventilation.
Do you install solar for farms in the Klein Karoo and Cederberg? Yes. We design around pumps, cold rooms, cellars, dairies and sheds, and we handle registration and the certificate of compliance.
Farm solar guides: irrigation and boreholes, cold rooms and packhouses, wine estates and cellars, dairy and livestock.
