Abstract
Determine using a mathematical model the energy efficiency of a heat pump that takes advantage of solar thermal energy from a photovoltaic panel under the climatic conditions of Itajubá city in Minas Gerais State - Brazil. The heat water and electricity produced simultaneously have the advantage of optimizing the use of physical space and obtaining better energy efficiency when compared to the performance of the equipment separately (photovoltaic panel and solar collector). For the development of the work, the system will be simulated in Matlab software. The mathematical model of the photovoltaic-thermal system (PV/T) includes a set of 4 unknown variables that must be solved simultaneously: temperature of the PV panel, evaporator, condenser, and water in the tank. The results showed that for a PV panel of 2.4m² it is possible to heat on a winter day 300L of water from a temperature of 16°C to 45°C and at the same time generate 2kWh of liquid electricity. For comparison terms, a conventional solar collector would need more than twice the area to achieve the same level of water production.
