PV electricity is booming world-wide and grid parity can be found in many countries. Nonetheless, animportant factor that still usually affects the economy of the PV project is the value of the power produced. Selfconsumptionis important in Sweden and on other markets where the bought electricity is higher valued than the soldelectricity. For many large roof tops, on-site batteries can be used as a measure for increasing self-consumption. Inthe present study, the logistics terminal owned by DB Schenker in Jönköping, Sweden, where a 20 kWp pilot plantwas installed in 2011, has been analyzed. The main focus is on the increasing self-consumption with batteries forelectric lifters. The results show that the self-consumption rate can increase 12 % (from 66 to 78 %) by using thepresent batteries for the electric lifters in the case-study, based on PV supply power (1 MWp) similar to the electricload capacity (1 MW). This enables 120 MWh per year more self-consumption out of annual 1000 MWh solar PVproduction. The conclusion for the Swedish case is that it is economically feasible to install battery inverters for onsitebatteries.
