On the intent of overcoming the partial shadowing effect, instead of shadowing on the solar module, sample areas were placed on the light source by varying the light amount on the solar module, and the same area measurements were repeated. The resulting area-current and area-voltage curves (Figures 4, 5, 6, and 7) were observed, and it was concluded that by shadowing on the light source, partial shadowing effects were diminished and the variation in the solar module’s current with area changes were linear with a regression coefficient,
