The concentrated gains in summer make the use of tracking system unattractive in improving the
winter PV yield. Further, the tracking system is economically infeasible as the 160€ or 208€ gain in energy cost/year as seen in Table 2 cannot offset the 4750€ or 8177€ cost of installing a single or dual axis tracking system respectively (Based on [53], 0.57$/W and 0.98 $/W is cost for 1-axis and 2-axis tracking system and 1.2$ = 1€).
