Energy assessment of a grid connected photovoltaic thermal (PV/T) liquid cooling system

  • 1 Faculty of Mechanical Engineering – Polytechnic University of Tirana, Albania


Solar energy has a great potential in Albania. The use of hybrid photovoltaic – thermal (PV/T) systems has shown an impressive progress in recent years. PV/T system can produce electricity and thermal energy simultaneously. In this paper, a 200 W PV/T system is introduced using water as cooling fluid, in order to regulate the temperature increase of the photovoltaic panels. The heat is collected via working fluid in a water tank. This study analyses the energy generation of this experimental setup, and aims to provide some accurate information in future developments and implementation of this technology in Albania. Coupling of PV/T system with heat pumps in buildings to meet the energy requirements could be of great interest for Albania’s energy consumers
