This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard is for persons in the Electrical Engineering; Generation; Distribution; Transmission, Construction and Renewable Energy Sector.

A person credited with this unit standard will be able to:
  • Identify symbols and components
  • Understand and describe the functioning of circuits and components
  • Sketch and construct a stand-alone photovoltaic circuit
  • Analyse solar and wind data
  • Calculate and determine loads
  • Calculate and determine appropriate battery ratings
  • Calculate and determine appropriate wind/solar hybrid ratings
  • Use computer software available for design purposes
  • Select the most appropriate components for the system
  • Complete task

    This unit standard will contribute to the full development of the learner within the electrical engineering and construction environment by providing recognition, further mobility and transportability within the field of Physical Planning and Construction. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the electrical engineering and construction environment.
