Does rain affect the energy production of crystalline photovoltaic modules?

In this sense, numerous studies have been performed in the past decades to assess the influence on the energy production of crystalline photovoltaic modules of several factors, such as spectral quality of solar irradiance, temperature, wind speed, soiling, snow etc. but so far the effect of rain appears scarcely investigated.

Does rain affect PV plant performance?

The site of Kurnool, in South India, falls in the tropical region and there is no detailed study has been conducted on the rain effect of the performance of the PV plant.

Does rain affect PV power plants during monsoon season?

A lot of utility-scale PV power plants are being installed in tropical regions owing to the increased sunshine hours especially during the summer season. The influence of rain on the performance of PV power plants during monsoon seasons in a tropical climate is not studied in detail.

Do solar PV plants perform well based on field conditions?

The performance of solar PV plants varies according to the locations and seasons [ 4 ]. The performance assessment based on field conditions provides more useful information to the policymakers and stakeholders about the global potential of PV production [ 5 ].

How does rain interact with the surface of PV modules?

Rain interaction with the surface of PV modules From a physical viewpoint, a water drop deposited on an ideal flat homogeneous surface is a system composed by three boundaries (solid/water, solid/air and water/air), where the water/air interface forms a static contact angle 1 θ (see Fig. 3) with the water/solid interface .

What is the average pr of a solar PV plant?

The average PR was found as 74.91% which is satisfactory. Generally, on average, CF of solar PV plants varies from 15 to 20%.CF is a measure of pre-estimating the plant's generation capacity/availability using yearly average solar irradiation. The 2 MWp power plant's average capacity utilization factor (CF) value is about 15.61%.
