Rising electricity costs and load-shedding have made solar power a practical necessity for many South African property owners, not just an environmental choice. But a solar installation is a construction project as much as an electrical one — and treating it as purely electrical is where a lot of installations run into trouble.
The Structural Side Gets Overlooked
Solar panels add real weight and wind-load to a roof structure. Before any installation, the roof needs a proper structural assessment — can it actually carry the additional load, and is the mounting method going to keep the roof watertight over time? Every bracket penetration is a potential leak point if it isn’t sealed correctly.
This is exactly where purely electrical contractors, without construction backgrounds, tend to get the wiring right but miss the structural and waterproofing side — problems that often only surface as leaks months later.
What to Check Before You Commit
- Roof condition and load-bearing capacity for the panels you’re planning to install
- Waterproofing at every mounting and penetration point
- Panel orientation and shading, which affects system output for the life of the installation
- Compliance with relevant electrical and grid-connection standards
How EHA Group Handles It
As part of our construction services, we treat solar installation as a full construction project — assessing the roof structure and waterproofing alongside the electrical work, not as an afterthought. The same integrated approach carries through everything we do, from solar installations to full builds and ongoing facility maintenance.
