Reasons to choose 
One Energy

Established in 2011, the One Energy Group is the largest and most successful renewable energy franchise network in South Africa, and today stands as an icon of service excellence and perfect installations in the industry.

We have a network of branches nationally, and we pride ourselves on the fact that every client across residential and commercial portfolios is a contactable reference

We constantly evolve our product solutions in line with new technologies, providing one of the most comprehensive solar energy offerings for the residential and commercial sectors.

Our suite of renewable energy solutions is procured only through premium, tier 1 suppliers who have the financial backing and proven reputation of standing by all product guarantees and warranties.

We are non-negotiable on aspects of product quality, technical capabilities, safety, warranties and guarantees, back-up and support available in South Africa and suitability for South African conditions – if you don’t find a specific product/brand on our list of hardware that we are prepared to install and sell to you – there’s going to be a very good reason for this. Ask us why and we’ll give you the rundown so that you can make an informed decision that benefits you in the long-term.

Over the last months, South Africa has been flooded with the entry of fly-by-night operators with no proven track record in technical or safety aspects in the market, and even cheaper products and solutions with questionable capabilities and value for money. Given the importance of the decision you are making with regards to your electricity cost, supply and safety, as well as quantum of your financial investment and expected ROI, make sure you are working with a credible, qualified and accredited renewable energy partner that will be around for back-up, support and ongoing consultation over the lifespan of your system.

Our driving business philosophy is summed up in two words – “Perfect Installations”. With over 13 000+ successful installations completed as at the end of 2021, we are extremely proud of our proven track record and unquestionably one of the highest service levels and business ethics in the industry.
