This paper presents the impact of relative humidity on the output of a solar Photovoltaic (PV). The relative humidity has influences on the other climate parameter as well as it is affected by them.
Based on (Kazem, 2015) humidity has the most influence on the performance of PV for this research, this is one of the factors used in analyzing PV performance. In this study the measurement of humidity used the DHT 22 sensor.
The PV's current, voltage and power output are decreased when the relative humidity increased. The correlation factorR found to be negative between humidity and wind speed, air temperature, solar radiation these are-0.6189,-0.9764 and-0.9681, respectively.
So, air temperature, solar intensity and wind velocity data was collected in Sohar city-Oman and compared with relative humidity for the period from July to September 2015. The results showed that relative humidity for the tested period is highly affecting the PV performance.
In simple terms, the higher levels of humidity lead to the formation of water vapor on the surface of the solar cell which reflects and refracts the incoming sunlight, . This inverse relationship is the subject of discussion of multiple related research articles -, which also confirm the observed behavior.
Solar inverters often encounter several humidity-induced issues, predominantly electrical and structural. Moisture ingress can lead to rusting of metallic components, affected solder joints,
