Småhusutformning och solenergiutnyttjande

Sammanfattning

This paper goes through solar energy and what uses it has. It is also a guide in the choice of solar collectors for

the 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 and

electricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely free

to extract, environmentally friendly and virtually maintenance-free. Disadvantages are that the technology is

expensive, does not cover the entire energy needs and takes a long time until it pays. Solar heat is extracted

through a solar collector, usually a flat solar collectors or vacuum isolated solar collectors. Solar electricity is

extracted usually by photovoltaic cells but also with the help of thermal processes. There are different types of

solar 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 have

mainly singled out more models that I compared with each other. I decided to choose

because it is the most affordable in relation to efficiency.
