Småhusutformning och solenergiutnyttjande
This paper goes through solar energy and what uses it has. It is also a guide in the choice of solar collectors forthe real estate that I have drawn for the thesis work.Solar energy is a renewable source of energy from the Sun's light. Energy can be used to produce both heat andelectricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely freeto extract, environmentally friendly and virtually maintenance-free. Disadvantages are that the technology isexpensive, does not cover the entire energy needs and takes a long time until it pays. Solar heat is extractedthrough a solar collector, usually a flat solar collectors or vacuum isolated solar collectors. Solar electricity isextracted usually by photovoltaic cells but also with the help of thermal processes. There are different types ofsolar cells in which crystalline silicon solar cells are the most common.Because I want a solar collector to cover a large part of the heating for hot water throughout the summer, I havemainly singled out more models that I compared with each other. I decided to chooseGJ140D.5 by SunmarkA/Sbecause it is the most affordable in relation to efficiency.
