Effect of wind on solar panel cooling in desert areas – pv magazine International



Whereas desert places are engaging locations for PV installations attributable to excessive photo voltaic radiation, publicity to harsh weather conditions can scale back the effectivity of the panels. One of many frequent issues is overheating of photo voltaic cells, and the problem is to discover a low cost, however environment friendly cooling method.

Now researchers from Mohamed First College and the Inexperienced Power Park in Morocco are investigating and quantifying the impact of wind as a pure cooling agent beneath sizzling dry climates. They uncovered the 300 W polycrystalline PV module for six months (in the course of the sizzling season) in Benguerir, mid-south of Morocco, and measured {the electrical} parameters of the module together with meteorological knowledge utilizing high-quality sensors. .

Their outcomes present that, even within the sizzling desert local weather, the wind has a optimistic impact on lowering the temperature of the PV module, enhancing the facility manufacturing in addition to the conversion effectivity.

Their knowledge present that the discount in module temperature (ie, the cooling efficiency) varies from 1.12 °C to 14.48 °C for wind speeds from 1 m/s to five.8 m/s. This results in a achieve in energy output from 0.12% to 7.18%, and an enchancment in module effectivity from 0.04% to six.45%.

Particularly, a rise in wind pace of 5.8 m/s ends in a drop in PV temperature of 12 °C, resulting in a rise in energy manufacturing and conversion effectivity by 7.2% and 6.5%, respectively. .

As well as, the research investigated the impact of wind course and confirmed that blowing wind (south wind) going through the entrance aspect of the PV panel confirmed a extra environment friendly cooling impact than blowing wind ( north wind), leading to a temperature drop of 13 °C. .

They introduced their findings within the paper “Experimental Investigation on the Impact of Wind as a Pure Cooling Agent for Photovoltaic Energy Crops in Desert Location,” printed in Case Research in Thermal Engineering.

“These outcomes might be vital beneath the pretext that they will present a good suggestion for engineers to higher select the internet hosting website of PV energy vegetation together with wind pace and course as standards, and to higher design PV energy vegetation within the warmth. dry climates to benefit from the wind and enhance the profitability and lifelong of this finish,” they concluded.
