The sub-centralized off-grid solar station was developed to supply energy to multiple households from a central location (nano-grid) . The unit caters for many energy applications with a whole range of available options and configurations.

Below is an image of an installation that was done on the outskirts of Cape Town for client Zonke Energy, South Africa in a suburb called Jabula where grid power(Eskom) is not available and the locals have been waiting for up to 30 years for electricity. It consists of a sub-centralized solar energy station which is a remotely managed off-grid solar energy system and produces renewable energy at a central point that then feeds out to the surrounding households in the area.
