    Author : Erik Larsson; Jesper Sundin; [2019]
    Keywords : PV; solar power; virtual storage;

    Abstract : In order to fulfil the goals set by EU and in the Swedish energy agreement an increased share of renewable electricity production, like wind and solar power, is necessary. Due to current legislations photovoltaic (PV) installations are usually limited to the 255 kWp energy taxation rule, or to fit the consumption profile of the building. READ MORE

  3. 3. Study of defects in PV modules : UV fluorescence and Thermographic photography for Photovoltaics (PV) Field Application

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Sophie Nylund; Zahra Barbari; [2019]
    Keywords : UV fluorescence; IR thermography; defects in PV modules; delamination; discoloration; hotspots; snail trails; cracks; fault in bypass diode; non-functioning cell in PV;

    Abstract : For a PV plant it is of fundamental importance that the operation of the PV modules is free from faults or at least that the faults can be detected early, to ensure efficient electricity production. Some defects such as cracks can be seen in visible light while microcracks and damage to the silicon material can only be seen through special lighting. READ MORE

  4. 4. The effects of low-emissivity window films on thermal comfort and energy performance of a historic stone building in cold climate: computer simulations with "IDA ICE"

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap
