How effective is water immersion in solar PV?

• The immersed solar PV is observed as one of the effective cooling methods. • An optimum immersion depth of PV is essential for heat dissipation. Sivakumar, B., Navakrishnan, S., Cibi, M.R. et al. Experimental study on the electrical performance of a solar photovoltaic panel by water immersion.

Does water immersion cooling improve photovoltaic panel performance?

Thus, a photovoltaic panel has a negative temperature coefficient that increases the current but drops the voltage potential. In this work, water immersion cooling of the photovoltaic panel is studied to improve panel performance. The module is studied with and without water immersion in a tank made up of acrylic material.

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.

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.

What is a solar power inverter?

It is a critical balance of system (BOS) component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for photovoltaic arrays and maximum power point tracking systems.

How does water depth affect solar PV efficiency?

The efficiency is increased by 9.1% compared to the PV without immersion at average solar radiation around 725 W/m 2. When the water depth increases beyond 20-mm immersion depth, the solar PV efficiency reduces. Therefore, the preferable water depth for the present tap water in a stagnant tank configuration is about 10–20 mm.
