Abstract
Applying new method for a Photovoltaic-Thermal (PV-T) panel system, analytical study was performed for electricity generation as well as desalinated water production. The PV-T panel was designed with a channel under it where seawater would be housed at a constant pressure of 20 kPa and ambient temperature of 15.8°C. The surface of the PV panel was modeled by a high absorption black chrome surface. Irradiation flux on the surface and the heat addition on the saltwater was calculated hourly between 9:00 am and 6:00 pm. The desorbed air then passed through a turbine where it generated electrical power, subsequently condensing into the desalinated water at the outlet. This gave an energy generation range for the turbine of 0.24 W to 1.12 W, while the desalinated water production range was 12.35 kg/ hr.m2 to 52 kg/ hr.m2. System efficiency was found to be between 7.5% and 24.3% and also the desalinated water production efficiency was found to be 40% to 43%.
