Thermo Group — Solar Experts You Can Trust
Affordable solar installations for homes and businesses in Stellenbosch — quality workmanship, transparent pricing, no premium mark-up.
At Thermo Group, we install solar PV, battery and hybrid systems throughout Stellenbosch — from wine estates and commercial cellars to heritage homes in the historic centre and student rentals near the university. Stellenbosch runs hotter and drier than the coast, and its solar registration goes through Stellenbosch Municipality rather than the City of Cape Town, so we design and register every system with that in mind.
Our experienced team handles the complete solar installation process in Stellenbosch — from surveying the property’s actual sun hours and shading, through design, installation, testing, compliance and registration.
Wine estates often need systems engineered around cellar cooling, irrigation pumps and pack houses, not a standard household design, while heritage homes and student-let properties bring their own roof types and priorities. We design around your property’s actual electricity usage and register systems correctly with Stellenbosch Municipality. We carry out both residential and commercial solar installations, and our technicians are experienced in installing and maintaining these systems for the long term.

What We Design Around In Stellenbosch
Wine Estate & Commercial Loads
Cellar cooling, irrigation pumps and pack houses need properly engineered systems, not a standard household design.
Heritage & Student-Let Properties
From Cape Dutch character homes in the historic centre to student rentals near the university, roof types and priorities vary widely.
Inland Heat, Not Coastal Salt
Stellenbosch runs hotter and drier than the coast, which changes panel de-rating and cable and inverter thermal planning.
Why A Stellenbosch Solar Installation Isn’t A Generic Cape Town Job
Stellenbosch is a different climate and a different municipality from the coastal suburbs we work in most — inland heat instead of salt air, wine estates with genuine commercial loads, and registration through Stellenbosch Municipality rather than the City of Cape Town. We design and register every Stellenbosch system with that in mind, not a coastal template.
Engineering For Wine Estates & Commercial Loads
Cellar cooling, irrigation pumps and pack houses run real loads that need to be properly assessed and engineered around, not estimated from a standard household system.
Designing Around Heritage Homes & Student Rentals
From Cape Dutch character homes near the historic centre to student-let properties near the university, we adapt the design and priorities to the property rather than applying one template everywhere.
Registering With Stellenbosch Municipality, Not The City Of Cape Town
Stellenbosch falls under its own municipality for SSEG registration, with its own application process and requirements. We handle that registration correctly rather than assuming Cape Town’s process applies.

We Don't Just Install — We Maintain
At Thermo Group, our relationship with our Stellenbosch clients doesn’t end when the solar installation is complete.
We offer ongoing maintenance and servicing for Stellenbosch solar systems, helping ensure equipment keeps operating safely and efficiently through inland heat, load shedding cycles and commercial wine estate demands. Our team can assist with inspections, fault finding, inverter issues, battery systems, electrical connections and general system maintenance.
Regular maintenance can also help identify potential problems before they become expensive failures.
SSEG & Stellenbosch Municipality Registration
Installing a solar system is only part of the process. Where required, your system must also be properly documented and registered — and in Stellenbosch, that registration goes through Stellenbosch Municipality, not the City of Cape Town.
Thermo Group can assist clients with the SSEG application and registration process, helping ensure that the required documentation, electrical compliance requirements and system information are correctly dealt with for Stellenbosch Municipality’s process specifically.
Our goal is to make the process as straightforward as possible for the property owner.

Book Your Stellenbosch Solar Installation
Fill in your details below and our team will contact you to discuss your solar installation or maintenance needs in Stellenbosch.
How much does solar installation cost in Stellenbosch?
It depends on your household’s usage and system size — a small backup system for essentials during load shedding costs far less than a full system covering your whole home. We assess your usage and roof before quoting, so you get an accurate price rather than a generic estimate.
How long does a solar installation take in Stellenbosch?
Most residential installations take 1 to 3 days on site, depending on system size and roof complexity, plus the time needed for approvals. We’ll give you a clear timeline once we’ve assessed your property.
Is the approval process different because Stellenbosch has its own municipality?
Yes. Stellenbosch falls under Stellenbosch Municipality rather than the City of Cape Town, which has its own SSEG registration process and timelines. We handle the correct process for your specific area, including installations at wine estates and student rental properties.
Will solar keep my home running during load shedding?
Yes. A correctly installed and configured solar and battery system will keep your essential circuits running during load shedding, and we size the battery to match your actual usage rather than guessing.
Do you also handle compliance certificates and ongoing maintenance for the system?
Yes. We issue the Solar Certificate of Compliance your installation needs, and we offer ongoing maintenance and fault-finding to keep it performing well for years — whether we installed it or another company did.
