Abstract:-This paper presents an extensive experimental performance evaluation and
comparative analysis of commercial mono-crystalline and poly-crystalline silicon solar
photovoltaic modules under variable irradiance and temperature conditions. Realistic operating
behavior is investigated through detailed current–voltage (I–V) and power–voltage (P–V)
characteristics, maximum power output, fill factor, conversion efficiency, temperature coefficients,
and performance ratio. Experimental results clearly indicate that mono-crystalline modules
exhibit superior efficiency, improved low-irradiance response, and lower temperature sensitivity
compared to poly-crystalline modules, while poly-crystalline modules remain economically
attractive for large-scale installations. The results provide valuable insights for researchers and
system designers for optimal PV module selection under real operating environments.
