Our History
Genergy was launched in 2008, when founder Terry Billson became an early adopter of what was then a fledgling industry in South Africa. He was joined by Co-founder Astrid Forbes. Together, they identified renewables and more specifically solar as a future oriented intervention for the security of the energy supply, and a tool for industry decarbonisation, cost savings and sustainability.
Almost 20 years later, their optimism holds true as the solar industry continues to grow on a global scale. As part of a rapidly developing industry, Genergy strives to adapt to new technological and regulatory developments as they come into being. With comprehensive experience spanning solar water heating and solar photovoltaics, Genergy has a proven track record of high performing system design and installation execution.
Genergy designs the optimal bespoke energy intervention to address expectations. It also facilitates the sustainability of energy supply, maximisation of savings, and longevity and quality of installation.
