We pride ourselves on removing all barriers to South Africans switching to new sources of energy and water by paying all upfront costs and selling services more affordably than the grid. Using advanced technology, we are able to not only put control back into your hands, but also increase your savings by using these precious resources as optimally as possible. There is no catch – we’ve created a business model that supports sustainability and gives you individual power to harness the potential of our world.
