PERFORMANCE ASSESSMENT AND DISTRIBUTED GENERATION BENEFITS OF THE FIRST GRID-CONNECTED, BUILDING-INTEGRATED PV SYSTEM AFTER 10 YEARS OF CONTINUOUS OPERATION IN BRAZIL
Ten years ago, in September 1997, the first grid-connected, building-integrated, photovoltaic (BIPV) system was installed in Florianopolis (48oW, 27oS), Brazil. The fully-monitored, 2kWp installation uses 40m2 of glass-glass, double-junction, thin-film amorphous silicon (a-Si) PV laminates, which were retrofitted to the existing solar energy research laboratory (LABSOLAR) building, at latitude tilt and facing north. The installation is connected to the low-voltage distribution grid via four line-commutated sinewave inverters, and has been operating and logging operational data continuously since start up. The negligible effect of temperature on the output performance of the a-Si thin-film technology, associated with the large solar energy resource availability in the Brazilian territory, and the consequent large PV module operating temperatures, were decisive in the original selection of this thin-film technology. This has resulted in high performance ratios (over 85％ and 80％ at the DC and AC levels respectively) and also in a high annual energy yield (1300 kWh/kWp/year for a 1550 kWh/m2/year irradiation level at the site) reported in this paper. Furthermore, with the operational results from this installation, we have been able to demonstrate the potential of grid-connected PV as a peak shaving tool in an urban area in a developing country. In this paper we show how PV can be strategically and conveniently sited in the metropolitan area of a capital city, in order to optimise the benefits of this distributed energy generating technology.
