Abstract This exam work is focus to streamlining solar collectors that are on the market today. The main purpose whit this is to get out more energy that is available. The objective of this is also to improve the coefficient of utilization in the solarcollektor that exist on KAU. The purpose is to find a cover glass that gives a better coefficient of utilization. The writer wills trough experiments find a cover glass that got an optimal ability to capture the sun energy. To find the optimal cover glass the writer will have to work with two parameters. The first one is the sun factor end the second one is the U-value. The advantage with a high sun factor is that you get a high inflow of the sun energy. The sun factor is a measurer of how match sun energy that transmission trough a glass construction. The advantage with a low U-value is that the cover glass get a good ability to isolate, in question of setting the heath energy free that the solar collector has captured. It is impossible to get a cover glass that has both a high sun factor and a low U-value. The writer idea is to find an optimal cover glass. The glass will contain both a high sun factor and a low u-value as may be possible. Answers to the goal with this project: Summertime: No (The coefficient of utilization is unchanged) Wintertime: Yes (The coefficient of utilization is improved)
