When designing a solar installation in South Africa, it’s not enough to choose panels with good ratings or a high-capacity inverter. The mounting system, the structural backbone holding everything in place, is just as critical. Local weather-conditions like intense UV, heavy downpours, strong winds, salty air (especially near the coast), and large temperature swings all put stress on solar mounts for South Africa. At Zephyr Solar, we understand these challenges and engineer mounting solutions specifically to withstand them. In this post, we’ll explain why your solar mounts for South Africa must be purpose-built for the local environment, and key factors to watch to ensure longevity, performance, and low maintenance.
5 Reasons Your Solar Mount Must Withstand South Africa’s Local Weather
South Africa’s climate is unforgiving: searing sun, coastal salt, sudden storms, high winds. Your solar mount must be built to handle it, not just now, but for years to come.

1. UV Exposure And Thermal Cycling
Intense sun (high irradiance) is one of South Africa’s assets but also its challenge. UV rays degrade plastics, coatings, and non-metal surfaces over time. Meanwhile, daytime heat followed by cooler nights causes materials to expand and contract, which can lead to loosening of joints, warpage, or fatigue if mounts aren’t designed with suitable thermal expansion tolerances and protective coatings.
2. Corrosion From Moisture, Salt, And Humidity
In coastal areas, salt spray can be extremely corrosive. Even inland, heavy rains or high humidity can lead to rust or corrosion if materials are not properly treated. Zephyr Solar uses corrosion-resistant materials like galvanised steel or aluminium, and protective finishes to ensure mounts resist degradation.
3. Wind And Mechanical Load Resilience
Strong winds, gusts, and storms are common in many South African regions. Mounts need to resist uplift forces, maintain structural integrity under side loading, and avoid vibrations that could fatigue structures and panels. Proper design for wind loads is essential to avoid wind damage or even structural failure.
4. Rain, Hail, And Severe Weather Events
Sudden downpours, hail, or storms can physically damage panels, but they also test the mount’s ability to stay sealed, resist bending or shifting, and avoid permitting water ingress where it can damage frame joints or connection points. Proper drainage and angles help shed water quickly, while strong joint design avoids deformation.
5. Soiling, Cleaning, And Long-Term Maintenance
Dust, bird droppings, soot, and salt (in coastal regions) can accumulate on panels, reducing output. A mount that’s too difficult to access, or made of materials that degrade with cleaning, will cost more over time. Also, mounts designed with open designs for airflow and easy access for cleaning mean better panel performance and less wear.
