ABSTRACT / САЖЕТАК:
Solar trackers have been used to increase the annual yield of solar photovoltaic systems, by tilting the surface of the panels in single or dual axis towards the sun. With dual axis tracking, the annual solar yield can be improved by more than 30%. Typical solar trackers include solar radiation sensors or estimated solar tilting based on GPS. Solar tracking systems, are typically fixed installations, where the GPS location can be determined only once, to define the tracking. Furthermore, some trackers include wind velocity meters, to reposition the tracker in the event of high wind velocities. With the development of the internet of things (IoT), solar tracking can be performed without typical sensors. This paper presents a cost benefit analysis of a mobile photovoltaic battery system for agricultural use, based on a foldable trailer mounted dual axis photovoltaic tracking unit integrated with storage and. Annual production data for Niš, Serbia obtained in TRNSYS are used to compare non tracking, single axis and dual axis configurations. The system is benchmarked against a diesel generator set operating on average 2500 h per year. For a 25 year lifetime and 5 percent discount rate, the photovoltaic tracking system shows significantly higher net present value and financial rate of return compared to diesel generation.
