In the present work, an experimental investigation is performed to assess thermal and electrical performance of a photovoltaic solar panel cooling with multi-walled carbon nanotube–water/ethylene glycol (50:50) nano-suspension (MWCNT/WEG50). The prepared nanofluid was stabilized using ultrasonic homogenizer together addition 0.1vol% nonylphenol ethoxylates at pH = 8.9. To reduce heat loss improve transfer rate between coolant panel, jacket designed attached panel. It also filled nanotube–paraffin phase change material (PCM) pipes were passed through PCM. MWCNT/WEG50 introduced into pipes, while nano-PCM in jacket. power system equivalent electrical–thermal assessed various local times different mass fractions MWCNTs. Results showed that increase concentration coolant, electricity production promoted, nanofluid, pumping augmented resulting decrease thermal–electrical power. identified 0.2wt% can represent highest 292.1 W/m2. 0.2wt%, ~45% 44% be produced (PV) 1:30 pm 3:30 pm.
