The BIPV systems are represented by the PV modules which substitute some facade or roof components. Along with the construction of new buildings - mainly residential parks and office buildings - the activity of retrofitting the existing stock is intense. Taking advantage of the necessity to upgrade the structural system of the buildings - as Romania is a country with severe seismic activity - the owners are trying to improve the living conditions also from the hydro-thermal, acoustic, functional and (more in a declarative manner, still), environmental point of view. They are more interested in the use of alternative energy sources (sun and wind based) as complementary measures to decrease the energy costs while using the energy their equipment requires. Though during the last years more private companies in Romania offered to merchandise and install PV systems, we cannot discuss of a proper PV market in the country. Compared with other European countries, Romania has an above-average solar irradiation in the summer, comparable to the one of Greece, country in which the solar/photovoltaic technology is highly developed. The paper presently a comparative analysis of three demo BIPV/PV systems developed within PASOR project (2007-2010), based on a national research programme.
