A comparative analysis of long-term field test of monocrystalline and polycrystalline PV power generation in semi-arid climate conditions

Monitoring the gross performance of both PV modules shows that the monocrystalline module performed better both regarding maximum efficiency and overall specific energy yield, and was found to be more efficient at this site. This work offers are also useful as a comparison for investigating the productivity of solar plants in different areas with climatic characteristics similar to the semi-arid region of Iran.
