Abstract [en]

With increasing energy needs and a greater demand of green power, the search of sustainable energy is becoming a bigger issue in the modern society. One of the solutions is solar power. Even though solar power is not a practical option as a primary source of energy in Sweden, since the energy need is the biggest during the winter, small scale solar power can still be used as a complement. Therefore a theoretical model for small scale solar energy is developed in this report.In this feasibility study both thermal and photovoltaic detectors and reflectors of the forms parabolic trough and parabolic dishes have been considered.To get an idea of how efficient the solar collector is some rough calculations are carried out.The result of the report is a hybrid solar collector of the type parabolic trough with a vacuum tube detector containing a u-pipe. To produce electricity it uses photovoltaic cells of copper-indium-gallium-selenide which produce an average of 0.55 kW over a year where the voltage out is 45 V and the current out is 12 A. By means of a pump the glycol-water mix flows through the pipe with a flow rate of 0.5 l/min and is heated from 15˚ C to 65˚ C. In this way hot water is produced and the solar cells are cooled to within the operating temperature. The overall efficiency of the solar collector is 74 %. The solar collector covers 11 % of a standard households electrical appliance and 38 % of a households warm water consumption.
