What Sun Worx does

Sun Worx is a South African solar photovoltaic (PV) integrator headquartered in Sandton, Johannesburg, that designs, installs, finances, and maintains commercial and residential solar PV plus battery energy storage systems. The company operates ten branch offices across South Africa and Uganda and reports more than 25MW of cumulative B2B installed capacity, over 25,000 installations across seven African countries, and an annual clean-energy production figure exceeding 100,000,000 kWh for a residential client base of more than 2,000 households. Originally founded as SolarTotal RSA in 2010, the company rebranded to Sunworx and positions itself with BEE Level 1, CIDB 7EP, and ISO 9001 credentials to access both private and public-sector contracts.

The company's commercial product surface spans rooftop PV, solar carports (reportedly scaled to 2.5MWp), battery energy storage integration (evidenced by a 1MW Mercedes-Benz Energy proof of concept at the East London plant), and premium OEM-aligned offerings such as BMW i solar carports and Tesla Energy certified installations. Its enterprise customer roster includes BMW, Mercedes-Benz, Toyota, Ford, FNB, Standard Bank, Nedbank, Anglo American, AngloGold, SAB, PRASA, SARS, Wits, Unisa, UFS, Singita Game Reserve, and Thaba Eco Hotel.

Sun Worx's business model combines direct enterprise project sales, an exclusive national retail partnership with Builders Warehouse for distributed residential and small-commercial flow, certified-installer relationships with Tesla Energy, SolarEdge, and Schneider Electric for premium component ecosystems, and long-tail service revenue under 25-year warranties. Pricing is project-based on capacity and complexity, with monitoring and maintenance layered as recurring revenue on a growing installed fleet.
