Can paraffin wax be used to cool a photovoltaic panel?

The high ambient temperatures in this geographic region make PCM cooling particularly impactful for mitigating PV efficiency losses. In this experimental study, paraffin wax with a 42 °C melting point was utilized as a phase change material (PCM) with a photovoltaic panel for cooling the panel and improving electrical performance.

Can paraffin wax be used as a phase change material?

In this experimental study, paraffin wax with a 42 °C melting point was utilized as a phase change material (PCM) with a photovoltaic panel for cooling the panel and improving electrical performance. A 4-cm-thick wax layer was integrated with a PV panel and the electrical results were compared to a conventional panel without PCM.

Can phase change materials absorb excess heat from PV panels?

High operating temperatures adversely affect photovoltaic (PV) efficiency, motivating research into cooling techniques. This study experimentally investigates using phase change materials (PCMs) to passively absorb excess heat from PV panels.

Does paraffin wax change the temperature of a PV/PCM system?

A review of a PV/PCM system using paraffin wax (RT28HC) in a cloudy atmosphere, at a maximum temperature of 35.6 °C and an average temperature of 14.4 °C, saw a decrease in the PV temperature. Because of the high latent heat of PCM (245 kJ/kg), the PV temperature remained nearly stable throughout the phase change process from 12:30 to 14:00.

Can paraffin wax be used as a PCM?

Paraffin wax with a 42 °C melting point was selected as the PCM and integrated in a 4-cm-thick layer on the back of a crystalline silicon PV panel. Temperatures were monitored within the PCM layer and PV back surface using thermocouples. A reference PV panel lacking PCM was tested under identical conditions.

Which nanomaterial can be used for self-cleaning coating on solar PV panels?

Apart from SiO 2 nanomaterial, titanium dioxide (TiO 2) is another well-known nanomaterial that can be used for self-cleaning coating on solar PV panels as it possesses both hydrophilic and photocatalysis properties. The developed TiO 2 /silane coating possesses the WCA below 10°.
