The Effect of Iraqi Climate Variables on the Performance of Photovoltaic Modules

This project presents the influence of the temperature, solar radiation, and wind speed on the performance of a Photovoltaic (PV) system. These effect has drawback effect of the electrical output of the PV (current, voltage and power). These climate conditions have massive impact on the PV performance, especially in Iraq due to its variable and severe environment. The study results revealed that temperature plays an important role effect on the performance of a Photovoltaic (PV) system. High intensity of Iraq solar radiation has an impressive effect of the PV performance. The effect of wind was limited as well as rain. The effect of dust and pollution accumulation was obvious. The studied parameters effect must be treated for Iraq to make PV technology wide spread in this country.
