UEECD0016 - Document and apply measures to control WHS risks associated with electrotechnology work
UEECD0043 - Solve problems in direct current circuits or
UEECD0044 - Solve problems in multiple path circuits
UEECD0046 - Solve problems in single path circuits

(Or equivalent to be determined by unit coordinator)


This unit involves the skills and knowledge required to solve problems with solar radiation, photovoltaic (PV) modules and the impact that tilt, location and orientation has on the output of a PV system.
It includes providing known solutions to predictable problems in photovoltaic energy modules and system operated at extra-low voltage (ELV) and low voltage (LV).The skills and knowledge described in this unit do not require a license to practice in the workplace provided equipment is not connected to installation wiring at voltages above 50 volt (V) alternating current (a.c.) or 120 V direct current (d.c.). However, other conditions may apply in some states/territories subject to regulations related to electrical work.


For Melbourne campuses

Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, incl the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills:
*applying relevant work health and safety (WHS)/occupational health and safety (OHS) procedures, including:

  • using risk control measures
  • checking tools, materials, equipment and testing devices for correct operation and safety
  • testing or measuring on live work and operating systems safely
  • ensuring circuits are isolated
    *providing viable solutions to apparatus/modules problems, including:
  • using problem-solving techniques to solve photovoltaic (PV) energy apparatus/modules problems from measured and calculated values
  • determining the operating parameters of an existing PV energy apparatus/modules
  • dealing effectively with unplanned events in accordance with workplace procedures
  • documenting justification for the solution used
    *using known solutions to predictable problems to solve apparatus/modules problems
    *measuring solar irradiance with a solarimeter
    *using field measurements and a sun path diagram, the times and dates when a PV array will be shaded by obstacles at a particular site
    calculation of:
  • the daily average irradiation on a horizontal plane given extra-terrestrial irradiation, location constants and sunshine hour data
  • the monthly mean daily irradiation falling on a PV array for each month of the year, adjusted for the effects of shading, using irradiance and irradiation data tables and a sun path diagram and/or appropriate software
  • the power at maximum power point (MPP), and the power under typical battery charging conditions of a PV module, given irradiance and ambient air temperature
  • the daily energy output of a PV array in accordance with relevant industry standards, and by using "rule of thumb" de-rating factors
    selection of an appropriate tilt angle for fixed and seasonally adjustable PV arrays at a given latitude.
