The Swedish Tourist Association, STF, is an organization which strives to make the Swedish nature more accessible to people. Since its founding, STF has been a key player in the development of the tourism in the Swedish mountain regions. Today the organization have 44 mountain cabins along the Swedish mountain range, and a majority of the huts are completely off-grid with no other connection to them but hiking trails. To accommodate for the needs of hikers and skiers throughout the year, the huts need electricity for lighting and in many cases cash registers and satellite modems to run small shops selling simple commodities. Many of the huts use solar energy combined with lead acid batteries, but not all of them can make it through the year without the use of a backup gasoline generator. This master thesis analyzes the different energy systems of four huts run by STF and using solar radiance data from PVGIS to calculate whether or not they are self-sufficient throughout the year using only solar energy. In the cases where the huts were found not to be self-sufficient, suggestions on actions that STF could implement to optimize the systems were found. For two out of the four huts, the thesis found that they were not self-sufficient, but after optimizing the energy systems with new energy saving appliances as well as tilting the solar panels between the winter and summer seasons, all four huts were found to be able to reach self-sufficiency.
