A world first, Specialized Solar Systems completed the installation of a sub-centralized solar energy power station in conjunction with an innovative client in Cape Town, Zonke Energy.  The installation was done on the outskirts of Cape Town in a suburb called Jabula where grid power is not available. It consists of a sub-centralized solar energy unit which is a solar energy producing station that supply’s remotely managed DC solar energy from a central point that will branch out to supply much needed solar energy to a further 9-11 house-holds.

Specialized Solar Systems utility-based solar management integrated solution will supply all the necessary tools in an easy to use, tiered-user, on-line framework for sustainable and remotely managed energy supply for the project. The integrated solution is used extensively in many off-grid solar electrification projects where remote system management and ground management rely on the real-time data with automated client billing, switching and comprehensive system management.

The second and final stage of the first Jabula sub-centralized off grid solar energy power station is now complete. This stage included six additional houses that were completely retrofitted for the supply of much-needed electrical energy. Our CEO,  Jonathan Hodgson was personally on site to assist with the challenge of laying the overhead DC cabling to each house and the complexities due to the informal building site layout and structures  - all done using poles and wired from the source installed street light (1).  

The installation was done on the outskirts of Cape Town, 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 that produces renewable energy at a central point that then feeds out to the surrounding households in the area.

All installed units are automatically managed using Specialized Solar Systems utility-based solar energy management online framework, SSS-EPOWER. The households are billed for energy usage with Pay as you Go billing bundles and users have the convenience of paying for energy usage at their nearest local general dealer almost at the location.

Some of the key features of Specialized Solar Systems integrated solar energy management solution used for managing the project:

  •     Solar system management with remote switching.
  •     User administration and management.
  •     A variety of automated billing options.
  •     Vendor payment facilitation and management.
  •     Stock control with system logistics.
  •     Advance security features.
  •     End-user interaction.
  •     Detailed reporting and systems overview.
  •     Audit trail system and user logging.
