Local context

What makes solar different in Western Cape?

Western Cape averages 9.1 peak sun hours per day. That figure is what actually determines yield: each 1 kW of installed panels produces roughly 9.1 kWh on an average day before losses, so a typical 8 kW array here lands around 58 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.

Solar in Western Cape: common questions

How many certified solar installers are there in Western Cape?

78 solar installation companies in Western Cape appear on South Africa's PV GreenCard register. They are spread across 3 cities in the province, and 4 of them are also members of the South African Photovoltaic Industry Association.

What is a PV GreenCard, and why does it matter in Western Cape?

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.

How much sun does Western Cape get?

Western Cape averages 9.1 peak sun hours per day. Peak sun hours are the practical measure for sizing a system: a 5 kW array in a province with 9.1 peak sun hours produces roughly 46 kWh on an average day, before losses from shading, wiring and inverter efficiency.

Are the installers listed here verified by SunVerified?

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.

Does an installer need to register my system with the municipality?

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.
