Estimation of DB Schenkers solar potential

Sammanfattning: Climate change, among others, has triggered the start of a global energy transitionand one of the most discussed technologies is solar energy and photovoltaics (PV),where the installed power has increased significantly during the last few years. DBSchenker is one company that recently have gained more interest in solar energy. In2011 they installed a 20kWp PV system on one of their terminals in Jönköping as apilot project to determine the most feasible construction of a PV system. This studyhave estimated DB Schenkers total solar potential when delimitations concerningsuitable roof area is taken into account. The first part of the study shows that onlyabout 11 % of the area is suitable due to smoke vents and suchlike, which in turnshows that the result of a realistic solar potential study is a lot lower than previous,more optimistic calculations where the whole area have been accounted for. Theenvironmental and financial consequences of such installations where also estimatedand while no PV system reach the MIRR limit of 13 % set up by DB Schenker as ameasurement of profitability, the PV installations could reduce DB Schenkers emissions with up to 2720 ton CO2-eq per year.
