Solar companies,
province by province.
Solar is a local business. Municipal registration rules, irradiance, seasonal generation profiles, and grid reliability all change as you cross a provincial boundary — so the installer market does too. These pages group Agrid's index by where companies actually record an address.

Nine provinces, nine different markets
- GautengSouth Africa's economic centre and the densest concentration of solar installers in the country.
- Western CapeA winter-rainfall market with the country's most established municipal registration pathway for embedded generation.
- KwaZulu-NatalA humid coastal and industrial market spanning the Durban port economy and inland agriculture.
- Eastern CapeAn automotive-manufacturing and renewables corridor with strong wind activity alongside a growing solar base.
- MpumalangaThe coal heartland, and the province where the energy transition has the most at stake.
- North WestPlatinum-belt mining and dryland agriculture across the western interior.
- Free StateHigh-irradiance agricultural interior where irrigation and grain handling drive daytime load.
- LimpopoHot, high-irradiance northern province driven by mining and irrigated agriculture.
- Northern CapeThe country's best solar resource and the centre of South African utility-scale PV.
Counts reflect the province recorded by the source for each company. 41 records carry no province and are reachable through the A–Z index below.
Where the listings concentrate
The distribution is heavily weighted: Gauteng (685), Western Cape (311) and KwaZulu-Natal (130) account for the large majority of listed companies, which tracks the country's economic geography rather than its solar resource. The Northern Cape has the strongest irradiance in South Africa and the fewest listed installers, because its solar story is utility-scale plant rather than rooftop retrofit.
Local context, not a template
Each provincial page lists the cities with enough records to be useful on their own, the inverter and module brands installers there record most often, and the companies whose records are most complete. Where a city has fewer than three listings it stays on the provincial page rather than getting a thin page of its own.
Agrid does not rank companies. Appearing higher on a page reflects how completely a record is populated, not commercial standing.
