Thermo Group — Solar Experts You Can Trust
Affordable solar installations for homes and businesses in Hout Bay — quality workmanship, transparent pricing, no premium mark-up.
At Thermo Group, we install solar PV, battery and hybrid systems throughout Hout Bay — a valley ringed by mountains on three sides, with a microclimate and harbour salt air that reach further inland than most homeowners expect. We design every Hout Bay system around those conditions from the first site visit, not as an afterthought.
Our experienced team handles the complete solar installation process in Hout Bay — from surveying the property’s actual sun hours and shading, through design, installation, testing, compliance and registration.
Whether you’re looking for a solar PV system, battery backup, hybrid inverter or a complete energy solution, we design around your property’s electricity usage, roof and the valley’s own weather. 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 Hout Bay
Mountain Shading & System Sizing
Chapman’s Peak, Karbonkelberg and the Table Mountain National Park ridge cut direct sun earlier or later depending on which side of the valley a property sits. We map actual sun hours on site before sizing a system, not off a generic Cape Town estimate.
Harbour Salt Air & Hardware Choice
A working fishing harbour means salt-laden air reaches further into the valley than most homeowners expect. We specify marine-grade brackets, connectors and earthing hardware at installation, so corrosion isn’t something a new system develops in its first year.
Valley Moisture & Roof Sealing
Hout Bay traps more mist and moisture than the open suburbs just over the mountain. Getting roof penetrations, flashing and cable routing right at installation matters more here than in a drier suburb.
Why A Hout Bay Solar Installation Isn’t A Generic Cape Town Job
Hout Bay sits in a valley ringed by mountains on three sides — Chapman’s Peak, Karbonkelberg and the back of Table Mountain National Park — with a working fishing harbour at its centre. That geography makes its own weather: more mist, more moisture, and shading patterns that change from one street to the next. We don’t quote a Hout Bay installation off a standard sun-hours table. Our site visit maps where the sun actually falls on your specific roof through the day, at different times of year, before we recommend a system size.
Getting System Size Right In A Valley That Shades Itself
Depending on which side of the valley a property sits, Karbonkelberg or the Table Mountain National Park ridge can cut direct sun earlier in the afternoon than an open suburb would get. Undersize a system without accounting for that and you end up with a homeowner disappointed by their own production numbers a year in. We size every Hout Bay installation around the property’s real sun hours, not a generic estimate for the Cape Peninsula.
Built For Harbour Salt Air From Day One
Hout Bay is built around one of the busiest fishing harbours on the Western Cape coast, and the salt air that comes with a working harbour reaches further inland than most homeowners expect — we see the same corrosion patterns here that we see in beachfront suburbs, even on homes with a mountain view rather than a sea view. Every Hout Bay installation gets marine-grade brackets, connectors and earthing hardware from the outset, so it’s not something that has to be corrected in year two.
We Install It, Then We Look After It
Once your system is installed, tested, and registered, our relationship with you doesn’t end. We offer ongoing solar maintenance and fault-finding in Hout Bay, from the same team that knows the valley’s mist, mountain shading and harbour salt air — and already knows your system’s exact configuration.

We Don't Just Install — We Maintain
At Thermo Group, our relationship with our Hout Bay clients doesn’t end when the solar installation is complete.
We offer ongoing maintenance and servicing for Hout Bay solar systems, helping ensure equipment keeps operating safely and efficiently despite the valley’s mist and harbour salt air. 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 & City of Cape Town Registration
Installing a solar system is only part of the process. Where required, your system must also be properly documented and registered with 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.
Our goal is to make the process as straightforward as possible for the property owner.

How much does solar installation cost in Hout Bay?
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 Hout Bay?
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.
Does Hout Bay’s valley setting affect a new installation?
Yes. Hout Bay’s valley traps moisture and morning mist more than drier parts of the Peninsula, so we specify equipment and mounting that can handle sustained damp conditions, not just occasional rain.
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 handle the City of Cape Town’s SSEG registration and Notice of Completion as part of every installation.
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.
