Project: Over 5MW of Agri-sector Solar Farm Design & Engineering
Project Scope:

Zero Point Energy was appointed by an agri-sector project developer to design & engineer several solar PV farms across South Africa. This included grount-mount and rooftop projects for farms in Limpopo, Western Cape, Northern Cape, North West and Mpumalanga.

The following engineering scope of work was conducted on projects:

  • PV Module layouts
  • DC string detail drawings
  • Electrical single-line diagrams of the PV plant up to LV-busbar distribution point
  • Optimal positioning of all electrical equipment, cable routes, DBs, etc
  • Soil resistivity testing (excluded in some instances)
  • Basic Earthing design for the solar PV plant (excluding grid connection earthing)
  • Electrical simulation studies
  • Load flow analysis o Short circuit studies
  • Protection co-ordination studies o Earthing simulation studies
  • Specifications of electrical equipment including: o AC and DC cabling
  • Cable trunking and cable trays
  • Fuses, circuit breakers and isolators
  • AC and DC disconnects and combiner boxes o LV sub and main distribution boards
  • Site visits and assessments
  • Construction engineering support
  • Issuance of digital and hard-copy sets of final design drawing packs
  • Pr.Eng – professional engineer sign-off on electrical designs


Location: 16x project sites across South Africa
Completion Date: Jun 2021
