Within the 2nd personal project assignment the subsystem chosen for discussion was a battery as part of a pv-system. To conduct a life-cycle analysis, followed by a multi-criteria decision analysis, research had to be made to identify the height of the costs in terms of energy, emission and water consumption. The results based on the type of battery being used are presented in table 2.5.1.

Tab.1 Option based energy consumptions and emissions — Tab.2.5.1 Option based energy consumptions and emissions

The battery characteristics for each design option are presented in table 2.5.2.

Tab.2.5.2 Battery Charateristics for PV application

Leading to the time-line options presented in figure 2.5.2.

Fig.3.5.2 Timeline Options — Fig.2.5.2 Timeline Options

and the radar plots presented in figure 2.5.3.

By adding weights to the different criterias being used, the results for TOPSIS 1 and 2 are presented in figure 2.5.4,
