Leading specialists in engineered Solar PV solutions and Battery Energy Storage Solutions (BESS)
Established in May 2010 by Jaco Botha and DeVilliers Botha, Solareff has established itself as a leading specialist in Solar Photovoltaic (PV) solutions in South Africa. Our SolareffSolutions team delivers engineered PV and Battery Energy Storage Solutions (BESS) that are optimised to meet our client’s unique energy consumption needs. Once installed, our SolareffAssets team provide comprehensive asset management services designed to enhance system performance, ensure compliance, and maximise your ROI. Through SolareffConnect, we offer innovative renewable energy financing, enabling clients to benefit from stable, lower-cost green electricity via long-term Power Purchase Agreements (PPAs). At Solareff, we’re committed to Future Focused Energy.
With a team of expert engineers and project managers, we’ve completed over 630 installations, delivering more than 260MWp and over 41kWh of commissioned and ongoing projects across Southern Africa.
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 Clearwater Mall Embedded Generation project, which was South Africa’s first commercial rooftop solar PV installation to break the 1MWp barrier for own consumption.

Driven by Purpose, Guided by Values
Our values are the foundation of everything we do, from how we work together to how we serve our clients and grow our impact.
- Selflessness: We are humble. We seek what is best for Solareff and care for the needs of others before ourselves. We are generous in our attention towards our teammates, customers and suppliers.
- Ownership: We see “Extreme Ownership” as a core value that emphasises taking full accountability for our actions, performance, decisions and the collective outcomes of our endeavours, regardless of the circumstances.
- Learning: We continuously learn, grow and build experience in an ultimate pursuit of competence and excellence, both in work and life. We train and share our knowledge and expertise to build a stronger team.
- Resilience: We are resilient. Not only do we bounce back from adversity, we embrace setbacks as opportunities for growth; summoning our inner strength to persevere.
- Excellence: We do not accept anything less than the pinnacle of quality and performance in everything we do for ourselves, our team and Solareff.
- Safety: We adopt an attitude of zero tolerance to keeping our people safe and free from harm in all environments. The well-being of our people is our top priority.
- Trust: We are vulnerable and transparent. We build our relationships with integrity and we are consistent in our actions towards each other, our customers and our suppliers.
Shareholdings
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.
