Whereas desert areas are engaging locations for PV installations as a result of excessive photo voltaic radiation, publicity to harsh weather conditions can cut back the effectivity of the panels. Probably the most frequent issues is overheating of photo voltaic cells, and the problem is to discover a low-cost, however environment friendly cooling approach.
Now researchers from Mohamed First College and the Inexperienced Vitality Park in Morocco are investigating and quantifying the impact of wind as a pure cooling agent below scorching dry climates. They uncovered a 300 W polycrystalline PV module for six months (throughout the scorching season of the 12 months) 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 scorching desert local weather, the wind has a optimistic impact on decreasing the temperature of the PV module, enhancing the ability manufacturing in addition to the conversion effectivity.
Their knowledge present that the module’s temperature drop (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 acquire 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 of seven.2% and 6.5%, respectively. one.
As well as, the examine investigated the impact of wind path and confirmed that wind blowing (south wind) going through the entrance face 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 offered their findings within the paper “Experimental Investigation on the Impact of Wind as a Pure Cooling Agent for Photovoltaic Energy Crops in Desert Location,” revealed in Case Research in Thermal Engineering.
“These outcomes will probably be essential below the pretext that they’ll present a good suggestion for engineers to raised select the internet hosting web site of PV energy crops together with wind pace and path as standards, and to raised design PV energy crops within the warmth. dry climates to make the most of the wind and enhance its profitability and lifelong,” they concluded.
