Study of Photovoltaics and Solar Thermal for Nearly Zero Energy Mediterranean Villas
Abstract
The development of modern nearly zero-energy buildings (NZEB) became possible with the combination of high quality architecture design and the addition of renewable energies (especially solar thermal and photovoltaic). The Renewable energies can cover all the energy consumption of the year. Solar thermal with Heat Pump and photovoltaic (PV) system for buildings has been designed to achieve different values of the fraction of a primary energy saving using the Flat Plate Collectors for Solar Thermal and solar photovoltaic (PV), and having the higher efficiency of the system with zero energy consumption. 13 different combinations have been studied in order to have higher savings with minimum investment and the result is the best is a high surface of photovoltaic (50-60 m2) and lower of solar thermal (10-16 m2).
