SOUTH Africans turning to solar to beat load shedding and soaring electricity prices have been urged to ensure their systems are installed by certified professionals, or risk safety hazards and unnecessary costs.
Proper solar installation: avoiding substandard systems
According to the South African Photovoltaic Industry Association (SAPVIA), the growth of rooftop solar has brought with it a spike in substandard installations that fail to meet safety and performance standards. To counter this, SAPVIA is promoting its PV GreenCard programme — an initiative that sets clear benchmarks for quality and compliance in solar PV installations.
Proper solar installation: PV GreenCard ensures safety
“The PV GreenCard acts as an ‘as-built’ report, issued by certified installers who’ve undergone specialised training,” a SAPVIA spokesperson said in an interview. “It’s not a replacement for a Certificate of Compliance, but a crucial add-on that ensures installations are done correctly and safely.”
Solar PV systems are becoming a staple in South African homes, with most setups now hybrid — combining solar panels, inverters, wiring and software that monitor power output. But many homeowners, once the panels are up, stop paying attention.
“Think of it like a car,” said Dr Rethabile Melamu, CEO of SAPVIA. “You wouldn’t drive for five years without a service. The same logic applies to solar systems.”
Proper solar installation Requires Regular Panel Cleaning
While the solar panels themselves require minimal upkeep, exposure to dust and weather over time can impact efficiency. SAPVIA recommends inspecting panels regularly and cleaning them at least twice a year. A drop in energy output by as much as 15% is a strong sign that cleaning is overdue.
The hidden risks lie in the components most users ignore — the inverters and batteries. These have a lifespan of between five and fifteen years, depending on quality, usage, and maintenance. High-quality equipment typically lasts longer and comes with better warranties, but even then, it’s not a fit-and-forget solution.
“Dust, debris, and loose connections can all chip away at performance,” Melamu said. “Regular inspection and cleaning are vital if you want to get the most out of your investment.”
Proper solar installation Demands Accredited Service
For those whose systems were installed a few years ago — especially before the solar boom of recent years — it might be time for a check-up. Calling in an accredited service provider to inspect wiring and insulation could prevent bigger problems down the line.
“And that’s where the GreenCard really proves its worth,” Melamu added. “It documents what was installed, when, by whom, and what warranties apply — making maintenance easier and more transparent.”
As more households and businesses look to solar as a long-term solution, SAPVIA’s message is clear: safety and quality matter. And the best way to ensure both is to stick with professionals who are trained, certified, and held to account.
