ABSTRACT

The project "Small Power Photovoltaic (PV) Systems for social objectives in remote areas (SPORE)" wishes to demonstrate the technical and economical competitiveness of PV systems for electricity supply in remote places, with the aim of improving the quality of life of people living in these regions and developing the mountain tourism. The development of standard PV systems for this kind of application is another goal of the present work. Ten PV systems have to be installed in different mountain locations not connected to the grid. The ten systems will supply with electricity: 6 schools –system A; 2 huts - systems B1 and B2; 2 cultural centers - system C.The sizing of PV generator is based on the monthly average solar radiation data (annual average value: 3.645 kWh/m2/day, measured at the nearby meteorological station). The battery capacity is calculated for autonomy of 15 – 20 days. An innovation is the availability of the system to supply different kind of loads (12 V dc, 24 V dc, 230 V ac), with two important consequences for the improvement of system Performance Ratio: optimized efficiency of system components and reduced "non-availability to load" period.
