  2. 22. Solar heat pump systems for heating applications : Analysis of system performance and possible solutions for improving system performance

    Författare :Stefano Poppi; Per Lundqvist; Chris Bales; Kai Siren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heat pump systems; techno-economics; solar thermal; system improvements; cost-effectiveness; Energiteknik; Energy Technology; MacSheep;

    Sammanfattning : Solar heat pump systems (SHPs) are systems that combine solar energy and heat pumps. SHPs have been investigated for several decades and have been proven to increase the share of renewable energy and reduce electric energy demand in residential heating applications. LÄS MER

  3. 23. Exploring the Role of Business Models in Large-Scale Diffusion of Solar Photovoltaics - A study of demand-side solar firms in Sweden

    Författare :Amanda Bankel; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; firm; innovation; sustainability; Sweden; photovoltaic; business model; diffusion; solar; system; policy;

    Sammanfattning : A rapid and large-scale diffusion of renewable energy technologies, like solar photovoltaics (PV), is crucial to slow down climate change. Research on technology diffusion explains that the rate and scale at which a new technology diffuses in society is influenced by the actors, networks, and institutions that make up its innovation system.

  4. 24. Combined Electrical Power Generation using Solar and Wind

    Författare :Ingemar Mathiasson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave length bands; atmospheric transmittance; energy storage; Wind turbine; wind speed; quantum dots; electrical load.; extinction coefficient; silicon solar cell; solar cell;

    Sammanfattning : The need for systems for renewable electrical power production is enormous worldwide.This applies to systems of varying size and capacity. From small systems for household purposes up to large systems for regional purposes. If possible, all systems should be linked in a common power grid. LÄS MER

  5. 25. Extreme solar particle storms and links to solar activity inferred from cosmogenic radionuclides in ice cores

    Författare :Chiara Paleari; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ice cores; cosmogenic radionuclides; Solar storms; 10Be; 36Cl; Solar energetic particles;

    Sammanfattning : During solar storms, large amounts of solar energetic particles (SEP) are accelerated into the interplanetary medium and sometimes hit Earth. These events, known as SEP events, can have harmful impacts on our modern society by affecting spacecrafts and potentially astronauts in space. LÄS MER
