PV System Design

The solar industry has had an everlasting impact on the electricity grid and has affected the power suppliers (such as Energex, Ergon, Essential Energy, PowerCor) in a way that could not easily have been anticipated. As a result, many of Australia’s power providers are still changing their regulations, exploring new equipment and safe guarding their network against a massive influx of solar generation.

Over recent months, we have been involved in assisting some of the power suppliers with technical aspects of connecting solar PV to the grid and they have showcased our technical expertise as an example to others in our industry. As new equipment becomes available, we work closely with the power suppliers to assist in their measurement of performance and regulatory satisfaction. We have an excellent working relationship with Energex(QLD) in particular and often liaise with their technical team in order to assist.

Complete system design including:

  • A suitable solar PV system size for your business based on your load profile / interval data
  • Site inspection to confirm the panel layout and cable route
  • Grid connection application including SLD and VRC to DNSP (Jemena, UE, Powecor, Ausnet, Endeavour, Essential Energy, Ausgrid, Energex, Ergon etc.)
  • Preparation of a detail grid connection approval report for commercial solar system including fault level calculation, back-up protections, particularly for DNSPs in VIC
  • Selection of panels, Inverters, AC & DC cable, DC & AC Isolators,
  • SLD / electrical schematic diagrams, Site Plan / Panel layout
  • PV array voltage matching to a particular inverter to optimise the performance of your solar system
  • Selection of protection relay for zero export / anti-islanding back-up protections/ grid protections
  • String protection, over-current protection,
  • Energy production estimate as per CEC design guidelines
  • CO2 saving equivalent to kWh energy generation of the system
  • Preparation of Bill of Materials (BOM) including price of the components and system
  • Financial analyses (ROI, Payback period, NPV, IRR)
  • Supervision of Testing & Commissioning of commercial solar systems
  • Preparation of testing & commissioning report for commercial solar systems
  • We would also arrange the third party Relay Pick-up test / Secondary Injection Testing of protection relay
  • RPEQ Sign-off for commercial solar systems in QLD
