Combined solar power and TPV

• In this paper design for a combined TPV and solar power system for local heat and power production is discussed. PV cells are producing electricity when there is light, while TPV cells are used when it is dark. Biomass is combusted and the heat is generating photons for the TPV system. Higher combustion temperature will give higher electric output, but also stronger deterioration of the materials in the combustor. By combining PV-cells that will generate a lot of electric power summer time with TPV-cells that can generate electric power winter time, when we also normally have a higher heat demand, we can achieve a flexible local heat and power system all year round. As both systems generate DC-power, we also can see a potential to use DC components generally, e.g for charging batteries for electrical vehicles, DC-pumps, LED-lamps etc. Design criteria for the systems are discussed in this paper for a house that is principally self sufficient on energy. Both theoretical and practical obstacles are discussed, as there are a number of issues to solve before the technique can be used in ”real life”.
