Established in May 2010 by Jaco Botha and DeVilliers Botha, Solareff (Pty) Ltd has become renowned as one of the leading specialists in Solar Photovoltaic (PV) solutions in South Africa, with the proven ability to deliver optimised PV and Battery Energy Storage Solutions (BESS) to effectively meet our client’s consumption requirements.

Our projects have included record-breaking installations such as the 7.216MWp solar PV rooftop solution at Eastgate Shopping Centre (currently the largest registered rooftop solar PV installation in South Africa); the 6.8MWp solar PV rooftop solution at Boardwalk Inkwazi in Richard’s Bay; and the 2.9MWp Clearwater Mall Embedded Generation project, which was South Africa’s first commercial rooftop solar PV installation to break the 1MWp barrier for own consumption. 

In August 2023, STANLIB Asset Management, a leading South African investor in sustainable infrastructure, acquired a controlling equity interest in Solareff, through its STANLIB Infrastructure Fund II.

STANLIB has committed substantial capital to fast-track the build-out of capex-free energy solutions for the C&I market through Solareff. This investment allowed us to establish SolareffConnect, offering clients stable and lower-cost green electricity through a long-term power purchase agreement (PPA).

 “We are all excited about Solareff’s new PPA offering to the market. STANLIB’s commitment to provide funding for capex-free power solutions and vast experience in managing infrastructure investments played a critical role in our choice of strategic partner. This investment is the beginning of our next chapter as Solareff continues to play a critical role in South Africa’s energy transition”

says Jaco Botha, CEO and co-founder of Solareff.
