Summary and Final Tasks

In this lesson, you learned about the special type of PV systems - concentrating photovoltaics. There are a few important features that make this technology attractive. They include:

  • high efficiency of light conversion (reaching 40% and above based on some laboratory tests);
  • small size of cells, which allows the use of less expensive PV materials;
  • economic land use by CPV systems.

At the same time, sophisticated design, necessary for precise tracking and cell cooling, is responsible for higher cost of CPV systems and high price of electricity compared to regular PV or non-renewable power generation systems. The activities in this lesson are oriented towards understanding some fundamental parameters of PV and CPV system analysis.

The table below summarizes all activities that are due for this lesson. Some of those have been included in the body of the lesson, and this list simply repeats them for your reference.
