Solar’s Compliance Era and What It Means for Installers of Solar Panels

Solar is entering a compliance era, and installers of solar panels need to be ready for it

Loadshedding built South Africa’s solar market almost overnight. Now regulation is catching up, and professional installers of solar panels are the ones who’ll decide how smoothly that transition goes.

As the 2020s began, loadshedding threatened the livelihoods of businesses and residents across South Africa. Almost overnight, a solar industry that sat on the fringes became a mainstream alternative.

Many people installed solar systems of varying sizes, adding 5.3 gigawatts (GW) of energy generation between 2023 and 2025. The South African Photovoltaic Industry Association (SAPVIA) estimates that the country is approaching 10GW of solar, and interest continues to grow.

Utility-scale solar sites represent roughly 52% of that capacity (Mordor Intelligence). The rest are among commercial and residential sites that use solar as power backup or a way to reduce energy costs. While these have largely expanded unabated, there is a clear shift towards a more compliant market: solar registrations with Eskom, and several major cities introducing installation approval requirements.

Different parties are still debating the details. But overall, 2026 is shaping up to be the year of solar compliance. This will have consequences for solar installers and integrators, according to Oscar Roberto Harbs Júnior, Solar Sales Supervisor at WEG Africa.

The teams that design and install solar systems are the industry’s front line, and they should be thinking about compliance. It’s not just a matter of legality and safety. How they understand and manage compliance will affect lead times and additional costs. Customers will ask them for clarity on compliance requirements. It’s not something that installers and integrators can afford to ignore.

Why credibility matters more for installers of solar panels now

New solar regulations have led to debate and concerns about certain processes. But nobody is against compliance as a principle. Any solar system that connects to the national grid, even if it doesn’t supply power to the grid, needs to be certified as safe and properly installed with vetted components.

There are many installers of solar panels that offer low prices and quick deployments. But increasingly, customers and other interested parties, such as insurers, are turning to certified and reputable installers to ensure they meet new compliance obligations.

This change will leave many installers and integrators in a precarious position. However, there are ways to close the gap between installations and compliance, starting with building their credibility and reliability through training and associations with trusted solar vendors.

Credibility is going to become more and more important, says Harbs. At this stage, the route to being fully compliant is still hazy. But the winners won’t be the ones who wait. When requirements become clear, they’ll be the installers, integrators, and system designers who are already certified and reliable, and who have built relationships with trusted solar vendors offering top equipment, consistent support, and nationwide supplies and troubleshooting.

Trained teams are compliant teams

WEG offers free training seminars to installers of solar panels and integrators, bringing them up to speed with installation methods, equipment knowledge and selection, and compliance basics.

Best effort is not enough if you want to remain competitive in a compliance market. Teams with the right training avoid mistakes that could cause failed site certifications and approvals.

So how do solar deployment companies actually benefit from closer vendor relationships and training?

As our solar partners move up the training ladder, they get more preferential access to equipment, support, and financial arrangements, says Harbs. Rather than rely on brands that might look cheap but come with little support or minimal friction replacements, they work with top solar brands like WEG to offer a comprehensive service, from design to installation to compliance considerations.

The South African solar market is entering a new stage. Compliance’s growing importance acknowledges a maturing market, and installers of solar panels must mature with it if they want to remain competitive and relevant. If you’re ready to move up that ladder, become a WEG systems integrator and access the training, equipment, and support that come with it.
