Mpumalanga has 20 PV GreenCard certified solar installation companies on South Africa's public register, making it one of the nine provinces covered by this directory. The PV GreenCard is issued by the South African Photovoltaic Industry Association (SAPVIA) and confirms that an installer has been trained and audited against SANS 10142-1-2, the section of South Africa's wiring code specific to photovoltaic installations. Mpumalanga averages 8.3 peak sun hours a day, which is what determines how much electricity a given array actually produces there. Certified installers are recorded in 3 Mpumalanga cities, concentrated in Mbombela (2), Middelburg (2), Secunda (1). 11 carry a public star rating, and every rating shown here is labelled with the source it came from. SunVerified has not independently inspected these companies' certificates, insurance or completed installations; listings reflect the public register only.
Local context
Mpumalanga averages 8.3 peak sun hours per day. That figure is what actually determines yield: each 1 kW of installed panels produces roughly 8.3 kWh on an average day before losses, so a typical 8 kW array here lands around 53 kWh daily once shading, wiring and inverter efficiency are taken into account.
Grid-tied and hybrid systems generally have to be registered with the local municipality as small-scale embedded generation (SSEG) before commissioning, and requirements and turnaround times differ by municipality. Ask any installer to confirm they handle the SSEG submission for yours. The solar cost guide covers what that process involves.

20 solar installation companies in Mpumalanga appear on South Africa's PV GreenCard register. They are spread across 3 cities in the province, and 0 of them are also members of the South African Photovoltaic Industry Association.
The PV GreenCard is issued by the South African Photovoltaic Industry Association (SAPVIA) and confirms that an installer has been trained and audited against SANS 10142-1-2, the section of South Africa's wiring code specific to photovoltaic installations. An installer without it may still be a competent electrician, but they have not been audited against the PV-specific wiring requirements, which is what your insurer and your municipality will ask about.
Mpumalanga averages 8.3 peak sun hours per day. Peak sun hours are the practical measure for sizing a system: a 5 kW array in a province with 8.3 peak sun hours produces roughly 42 kWh on an average day, before losses from shading, wiring and inverter efficiency.
Not yet. Every company listed is genuinely on the public PV GreenCard register, and each profile links to its entry there so you can check. But SunVerified has not inspected their certificates, insurance schedules or completed work. Our own "Verified" badge is only applied after that document review.
In most South African municipalities a grid-tied or hybrid system must be registered as small-scale embedded generation (SSEG) before it is commissioned, and the application usually needs a certificate of compliance plus a signed-off electrical drawing. Ask any installer to confirm they handle the SSEG submission for your specific municipality.
