Photovoltaic (PV) Technology.

Intended Learning Outcomes

The students will be able to:

  • retrieve and collate comparable data from several sources using a spreadsheet.
  • analyse data graphically or statistically to identify imbedded patterns, correlations, and anomalies.
  • use the concepts of insolation (solar flux density reaching the earth's surface), angle of incidence, energy conversion, and the diurnal solar cycle to explain patterns in the data and predict future measures.

Teaching Rationales

Students investigate the performance of photovoltaic cells to estimate the efficiency of conversion of solar energy to electrical energy and to investigate the effects of load resistance, distance from source and orientation of the solar cell on output.
