About GreenSun

As a Solar Energy Solution provider since the beginning of 2012, GreenSun has quickly established itself and has built a reputation for delivering innovative and sustainable solutions, in the solar energy and renewable power industry, throughout the Western Cape.  ANXA Technologies CC trading as GreenSun Solar Energy Solutions was born out of ANXA Construction (NHBRC registered – 2006) when it was decided to expand on our existing reputation by adding additional projects to our resume in areas including renewable power and sustainable energy solutions.  Based on the needs of each individual client, Greensun embraces and provides a variety of solar energy options as well as an array of systems and methods to offer the most effective and efficient solutions for each project.  We pride ourselves in our commitment to our clients, safety and use of superior products to ensure the highest return on investment through outstanding quality and efficiency of our systems, exceptional client service and team integrity.

Company Structure

GreenSun employs a hands-on philosophy from both an operational and administrative perspective.  By positioning ourselves as a once-off solution to all energy needs and requirements, each client gets the best of what our expertise and specialist services have to offer.  By staffing each individual with a project manager, both our clients and our firm can be assured that each project gets handled professionally and is of the utmost importance.  Each project gets initiated by our administrative team that assists with individualised design and costing and handed over to the operational team that is supported with on-site staff ranging from an installation team, systems design team, qualified solar technician and certified electricians.

We mainly concentrate on the installation of Photovoltaic (PV) systems in the following categories:

Apart from these installations our clients have requested other services, including:

  • Cost estimation and quotation (per project) – on full range of entry level and bigger systems
  • Solar pumps
  • Heat pumps
  • Solar panel powered lamp posts and billboards


Client service is our priority while client satisfaction is the constant measure of achievement for our team.  Although we are certain that this satisfaction can be contributed to our dedication and commitment to all our clients, it is also directly related to the company values through which GreenSun manages its entire operation.  These values are:

  • Leadership
