Nelson Sommerfeldt is a Postdoctoral Researcher at KTH Royal Institute of Technology’s Energy Systems Engineering, Economics, and Data Analytics (ENSEED) research group. His work centers around the techno-economic integration of solar photovoltaics in building energy systems, and ranges from individual component development up to systems level control and management. Recently the ENSEED group has branched into user perspectives on system performance given the importance of perceived benefits towards the increased adoption of renewable energy in society.
