Solar Energy Soluitions

Company profile

oneSolar has been established in 2008 by Wehrner Kohn. Wehrner has been spending 8 years abroad before returning to South Africa where he was looking for a new challenge. The energy sector has been proven to be such a challenge and Wehrner’s background as an Industrial Engineer has equipped him well for the area of optimisation and quantification.

The rising energy cost has placed more emphasis on investing in newer and more efficient equipment. The trick is to invest first and then reap the benefits over years.  This is why we select our products based on their efficiency and life expectancy. It does not always come as the cheapest solution but your investment makes only sense, if you can reap the benefits well over and above the pay-back period.

oneSolar’s focus has always been a high level of quality – in product as well as in installations. We are part of several programmes and meet all necessary requirements in electrical or plumbing standards.

Our professional sales consultants, project managers and installers have sound experience in all aspects of the installation. The Solar Industry is a new and wide area of knowledge. We provide ongoing knowledge transfer and training to our consultants and installers to equip them with the necessary skills to do the job and to improve their competence.

For our customers we provide a well-designed and tailored solution and deliver what we promise.
