dc.description.abstractWith growing amounts of the worlds electricity supply coming from renewable sources, the intermittent nature of these sources demand an increase of energy storage. In addition to the need for energy storage on grid level, storage also provides possibilities for individual households to use larger amounts of their own produced electricity. The aim of this study was to examine what barriers the households that install battery storage systems in Sweden encounter, and to investigate how they use the storage systems. The objective was achieved by collecting and analyzing interview data from households with solar PV coupled with battery systems, as well as survey data from households with only solar PV installed. The findings further highlight barriers that have been previously identified for early adopters of solar PV in Sweden, with the relative value of producing electricity not reaching a level where the significant investment cost is justified. In the case of the battery system, the gap in value between using the produced electricity from the solar panels through the battery compared to selling it to the grid is not substantial enough to make the investment worthwhile. A major factor creating this situation is the tax reduction of 60 öre/kWh received for selling produced electricity to the grid. Information retrieval was not perceived as a major barrier for owners of solar PV and battery systems since this group of people possess a relatively high level of technical know-how. Improvements regarding available information on back-up power usage of batteries as well as a way of easily comparing offers from companies was requested by study participants. The batteries are usually charged with electricity from the solar panels that is not directly consumed. By charging the battery from the grid at times of low electricity prices the financial situation of an investment in a battery system could be somewhat improved, with some battery owners requesting this usage to be automatic in the future. Simplified and long-term legislative frameworks would further encourage adoption. Development of business models that could handle administrative work and guarantee revenue streams would also be of benefit.
