Project Client:                Local subsidiary of a USA-based utility-scale renewable energy project developer

Project Name:                 10x utility-scale solar PV projects in the 6-12MWp range

(project names confidential)

Project Location:            Across Gauteng, South Africa

Contract Description:    Zero Point Energy was appointed to do the following scope of work:

Preliminary design:

• Review & analysis of key equipment datasheets. The equipment includes:
  • Solar PV modules
  • Fixed-tilt mounting structures
  • Single-axis tracker structures
  • Solar grid-tie inverters
• Determination of the following:
  • Suitable number of modules and inverters
  • Suitable fixed-tilt angle (for fixed-tilt options)
  • Suitable pitch/spacing distance rows for shading considerations
  • Suitable table size
  • Suitable string size
  • Suitable strings per inverter MPPT input(s)
  • Suitable number of rows per tracker block (tracker option)
  • Suitable placement of inverter blocks
  • Suitable location of substation, O&M buildings, internal roads, etc
• Site layouts:
  • Site layouts will be provided for both fixed-tilt and tracker options. This will involve the provision of CAD drawn general site plan layouts
  • Site perimeter fencing
  • access point (to be communicated by client)
  • Security and guard house
  • Access, peripheral and internal roads
  • Substation and control room buildings
  • O&M building location
  • Exclusion zones (if any provided by Client)
  • Inverter station locations
  • Fixed-tilt / Tracker mounting structure blocks
  • Total road length and area
  • Total perimeter distance
  • Total PV footprint area
  • Number of modules
  • Number of strings
  • Number of modules per string
  • Plant DC and AC capacity

•  Solar yield simulation studies per site:Bankable (P90) and detail design yield analysis
  Yield report with discussion on study assumptions, technical configuration, climatic data,  system losses, 20 year generation forecasts, and results
