Comparison of PV systems in different modes of operation

In present time PV plants in Croatia are expanding rapidly due to state incentive on PV energy production. Such state of market enables investiture regardless of energy efficiency since prices of energy are very high. In near future prices will not be so high and every improvement will be valuable if it can provide additional energy production. One way of increasing energy production of PV module/plant is implementation of single or dual-axis tracking systems. In this paper some specific characteristics were compared for different PV module modes of operation, and measured energy production is compared for every mode of operation with fixed instalation in urban surroundings.
