How does water immersion affect PV panels?

PV panel surface temperature increases, and the PV panel’s efficiency decreases due to thermal conduction. Water immersion is one way of cooling PV panels, but the proper depth of immersion is required to trade off the solar radiation and PV efficiency. More immersion depth leads to the loss of incoming radiation and transmissivity losses.

Does inclination affect electrical performance of underwater PV panels?

The electrical performance of underwater PV is studied at horizontally placing the panels. However, the further studies on the inclination of PV appropriately with the site’s latitude could be investigated to obtain more results. The heat convection occurred from the PV panel to water, and the PV top and bottom surface cooled.

How do PV panels affect water quality?

Large areas of PV panels cast shadows on the water surface and thus can reduce light availability to waterbodies, and floating materials on the water surface reduce contact between the air and waterbody, which may lead to reductions in water temperature and dissolved oxygen 17, 18. These changes might impact aquatic organisms.

Can a PV panel cooled by a water flow produce more electrical current?

The PV panel cooled by a water flowing can produce more electrical current compared to the standard PV panel without incorporated a cooling water flow as shown by the variations of the Pec values in Fig. 4 b at all the pairs of points higher than those in Fig. 4 d accordingly.

Can a water cooled PV panel generate additional thermal power?

Even though many physical models of the PV panel have been proposed to generate electrical power (Kalogirou and Tripanagnostopoulos 2006 ), the development of water-cooled PV panel generated an additional thermal power could be cost effective if the additional cost of thermal unit used is low.

What is the efficiency of PV panels based on water immersion?

The panel efficiency with an immersion depth of 10, 20, 30, and 40 mm is approximately 15.02%, 15.54%, 14.58%, and 13.95%, respectively. The results show that the immersion of PV panels in tap water 20 mm increases the PV efficiency by 9.1% compared to the PV without water immersion.
