Thermo Group — Solar Experts You Can Trust
Affordable solar installations for homes and businesses in Century City & Milnerton — quality workmanship, transparent pricing, no premium mark-up.
At Thermo Group, we install solar PV, battery and hybrid systems across Century City’s business parks and Milnerton’s coastal homes — two very different environments that call for two different installation approaches, from a single experienced team.
Our experienced team handles the complete solar installation process for both commercial and residential properties — from assessing the roof, roof orientation and electrical load, through to installation, testing, compliance and registration.
Whether it’s a three-phase commercial system on a Century City office roof or a hybrid inverter and battery setup on a Milnerton home, we design around your building’s actual usage and environment. 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 Century City & Milnerton
Commercial Roofs vs Coastal Homes
Century City’s flat commercial roofs and business-park carports need three-phase systems sized for real office loads. Milnerton’s older coastal homes need a residential system specified for wind and salt air, not a generic inland install.
Coastal Wind & Salt Air In Milnerton
Established homes near Milnerton Lagoon and Woodbridge Island face constant salt-laden air off Table Bay. We specify corrosion-resistant mounting and connectors from day one, the same as we do further up the coast in Blouberg and Table View.
Site Access & Sign-Off In Century City
Century City’s office parks run on body-corporate rules and strict site access. We plan installations around business hours and hand over documentation the facilities manager, and the tenant paying for it, can actually use.
One Team, Two Very Different Installation Jobs
Century City and Milnerton sit side by side on Cape Town’s northern doorstep, but they call for two different kinds of solar installation. Century City is a master-planned precinct of canal-side office parks and commercial buildings built around the N1. Milnerton is one of the oldest suburbs on this coast, established back in 1904, sitting right on Table Bay next to its lagoon. We install in both, and we scope each job around which one we’re in before we ever spec a panel.
Installing Solar On A Century City Business Park Roof
Century City’s buildings were mostly designed with flat commercial roofs and generous parking structures, which suit rooftop or carport-mounted solar well. Because the electrical loads here are commercial, not residential, we plan for three-phase systems, indoor inverter rooms tucked into service corridors, and DB boards sized for the business now running off them, not the smaller office that may have occupied the space when it was wired. Site access is managed by the body corporate, so we schedule installation work, permits and sign-off around business hours and site rules from the outset.
Installing Solar On An Older Milnerton Home
Milnerton has been a settled residential suburb for over a century, with homes near Milnerton Lagoon, Woodbridge Island and the old lighthouse a short walk from the beach. Coastal wind and the cold Benguela current push salt-laden air off the bay every day, which ages exposed brackets, connectors and cabling faster than most homeowners expect. Every Milnerton installation gets corrosion-resistant mounting hardware and properly sealed connections specified up front, not added later once we’re called back for a fault. On some of these older properties we also check the distribution board and earthing are up to a standard that can safely carry a new solar installation, since the house’s original electrics were never designed with solar in mind.
We Install It, Then We Look After It
Once your system is installed, tested and registered, we stay involved. We offer ongoing solar maintenance and fault-finding in Century City & Milnerton, from the same team that already knows your system’s configuration and this area’s two very different environments.

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.

Fill in your details below and our team will contact you to discuss your solar installation or maintenance needs in Century City or Milnerton.
How much does solar installation cost in Century City and Milnerton?
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 Century City and Milnerton?
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.
Do you install commercial solar systems in Century City?
Yes. We install rooftop and carport-mounted commercial solar systems across Century City’s office parks and business units, including inverter rooms and battery installations, alongside residential systems in Milnerton.
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.
