This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers. This reference plant owned by the University of Waikato is installed on the library roof and is the point of reference for both software´s in the calculation of electricity production.The subject of the thesis concerns the solar energy with a focus on grid-connected photovoltaic systems and beyond that the work has also led to an investigation of solar radiation, solar cells and how to use information from different weather databases. In this project a widely used database "Typical Meteorological Year 2" with 20 years of age measurements of solar radiation is used and compared to the latest information available. The handiness and suitability of both software´s were also evaluated to see if the software´s are good enough for teaching at the University of Waikato.The conclusion made by the writers is that TRNSYS can be used in teaching at the University of Waikato but PVSYST need further investigation. TRNSYS is suitable because of its performance accuracy and detail in the building modeling. The writers cannot recommend PVSYST as the investigation of the software was not completed due to the lack of time. PVSYST does likely have the potential to be an educational tool, but it remains to be investigated.
