The main aim of this thesis work was to develop, test and build good, simple solar energy experiments to illustrate the possibilities of solar energy. These experiments should support the exhibition “Nedkalla solkraften” by showing the possibilities and different forms of solar in “hands on” experiments. The main aim has been reached, mainly illustrated by the fact that - the experiments are good representations of solar energy technology, even showing the problems encountered with these techniques in practice; - a cheap good-working dye-sensitized solar cell demonstration has been developed; - existing experiments have been efficiently implemented (like the s(ch)olar collector); - standard manual were made; - the whole process has been performed within the financial outline set by the Tekniska Museet But of course there were also some problems, like - there was not enough knowledge about the environment in which the experiments were going to be used; - not all experiments were robust enough; - the standard manuals contained too much (complicated) text and too few illustrations to be used easily; - the time to develop and build the experiments was not very long; - the evaluation of the exhibition is not reliable, because too few questionnaires were handed out and returned. The penultimate problem is one of the main causes that no advanced testing has been performed. After implementation, it seemed that it might have been interesting to compare “research results” with field results. This in order to see how easy experiments are to reproduce. Based on this “lack of research”, it can be said that this thesis work was maybe too mu...
