Abstract:
In this study, polycrystalline and monocrystalline PV modules were characterized in three conditions,
namely without coating (TC), single coating (SC), and double coating (DC). Based on the results of
the I(V) characterization, the PV module coated with coating produces greater power than without
coating. The value of efficiency increases with increasing power, where the PV module given a
coating layer has a greater efficiency than without coating. This is because the coating layer has a
low absorbance which effectively reduces the reflectivity of the glass surface. Monocrystal PV
modules that are given a coating have increased efficiency in singlecoating, which has increased by
0.4% and for doublecoating, there has been an increase of 1.04%, the coating has a low absorbance
which effectively reduces the reflectivity of the glass surface. The polycrystalline PV module that was
given a coating layer experienced an increase in efficiency, with singlecoating an increase of 1.7%
and for double coating an increase of 3.0% with a time variation of 12.00 WIB. Variations in
resistance and voltage change but are not very significant.
