PHOTOVOLTAIC SYSTEMS, BASIC COURSE | AEB020 |

**Aim**

There is from a national and global point of view necessary to develope renewable energy technologies for generating electric energy. PV-system will in the future be one of the most important technologies for producing electricity. The course aims at teaching basic knowledge of how solar cells and solar cell systems works in different applications. In Sweden building integrated PV-systems are most interesting. In the developing countries where many people lives outside the electric grid, stand alone PV systems are of great interest. The ability to simulate the performance of PV-systems is an important part of the course. After the course the student should be able to perform a prestudy of the installation of a new PV-system

*Knowledge and understanding*

For a passing grade the student must

- be able to describe the national and international use and demand of energy and the importance of the renewable energy sources.
- understand and be able to describe how different types of solar cells work
- understand and be able to describe how grid connected and stand alone PV-systems can be used for generating and conserve electricity.
- understand and be able to describe the advantages and limitations of PV-systems
- understand and be able to describe how the PV system interact with the electricity system

*Skills and abilities*

For a passing grade the student must

- be able to estimate and describe the use of energy in a building
- be able to charcterize a PV-module, i.e. measure the IV-curve
- be able to use a simulation programme for estimation of the energy delivered from a PV-system
- be able to construct a stand alone or a grid connected PV system and describe how its components work
- be able to use a simulation programme for estimation of the solar irradiance towards surfaces in different geometries.
- be able to with different methods calculate the cost for PV-electricity and competing technologies

*Judgement and approach*

For a passing grade the student must

- be able to take part in and analyze the current discussion of energy use and global environmental problems
- be aware of the influence of the building design and the energy system on the energy use of the building
- be able to perform a critical analysis of the use and value of delivered solar energy
- learn to critically evaluate and analyse information in general
