His professional legal background has enabled DeVilliers to develop unique and extensive expertise relating to the legal, compliance and financial aspects of energy projects. DeVilliers is currently championing the drive for enabling regulation regarding the current legislation (ERA Schedule II) and represents SAPVIA through SAREC at the BUSA and NEDLAC processes.
DeVilliers regularly presents training on behalf of SAPVIA to enable Municipalities to understand the role of industry in the future of renewable energy.

During 2017, Solareff expanded into green mobility through the acquisition of GridCars. Under his Directorship, GridCars has successfully installed South Africa’s most extensive EV charging network. His passion for Green Living is evident in his lifestyle – not only is he driving the “bigger picture” for industry, but his home is powered via a Solar PV system and he charges his EV from the Sun as much as possible – proving that living the Green Lifestyle is not a distant dream but rather is a current reality in South Africa. “Disruption is only disruptive to those that are slow to embrace change”.
