Abstract: This work presents an in-depth, practical approach to ascertaining the efficiency of monocrystalline and polycrystalline solar panels. Solar power is gradually making its way into the domestic and industrial space, replacing older (less environmentally friendly) sources of power. Their efficiency and other performance parameters are worth analyzing so as to establish methods of improving existing solar technologies. Various tests were conducted to determine the energy conversion characteristics of two types of solar modules. The results of the test for a duration of five days revealed that the maximum and minimum efficiencies for monocrystalline panels were 33.05 percent and 3.36 percent, respectively; for polycrystalline panels, they were 31.44% and 1.13%, respectively. This gave rise to average daily efficiencies of 19–22% and 13–20% for monocrystalline and polycrystalline modules, respectively, which are within the industrial-rated efficiency values obtainable for both solar panels. The reason for these obtained results may have arisen due to the availability of sunlight for most of the period of the experiment. However, suggestions were made at the end of the research to further improve the already established efficiencies of solar panels.
