About Us
Established in 2011 we have level 1 BEE certification. We offer end-to-end renewable energy solutions that help our clients to reduce their energy costs using state-of-the art technology and products.
The move to solar power generation is an obvious choice in South Africa considering that South Africa receives 2 500 hours of sunshine per year in comparison to Europe’s 1 000 hours of sunshine per year. Plus the rising cost of electricity in South Africa makes going green a compelling option for businesses and residents to consider.
We are inspired by the growing focus on sustainability and believe that renewable energy solutions are critical to reducing greenhouse gas emissions and the pressure on the environment.
We offer a range of professional energy solutions to our clients from energy audits right through to full installation and ongoing maintenance of solar powered systems. We are pioneers at heart and we are committed to offering creative solutions and high-quality installations that comply with local legislation and conform to the highest international standards.
