Abstract [en]

In this thesis, performance of the PV system on the facade of the Oseana building is

evaluated. The thesis was done at the Institute for Energy Technology (IFE), which is

situated in Kjeller, Norway. The building of the PV system that is being analyzed in this

thesis is situated in Osøyro, Os Kommune, which is located south of Bergen. The analysis

was carried out by modelling the building and the PV system in PVsyst, a software package

specifically used for sizing, simulation and analysis of complete PV systems. Simulations

were performed on user-defined models based on the original system, whilst considering

different cases, the results from these simulations were compared to the inverter output

data, and conclusions were derived.

The building with the PV system under study has a unique architecture, having a curved

facade with the panels mounted on this curved facade. The facade also has a walkway

coming out of the third floor window, which causes shading. The effects of the shading

caused by the walkway were analyzed. Simulations were carried out for different cases and

the results were compared to derive conclusions.

Different weather data sources were considered and used in the base simulations to

identify the most relevant data source. Once the best data source was identified, further

simulations were carried out to generate outputs such as the system’s annual yield, losses

and performance ratio. These simulation outputs were then compared with the actual

annual outputs of the system. The performance ratios of the simulated systems, with and

without the walkway are obtained and a comparison between them is made. The probable

values of global horizontal irradiance are calculated and these values were compared with

the annual yield of the system to check if the data would match. Probability simulations

were also carried out to determine the percentage chance that the system would yield a

certain output value in any given year. Furthermore, the orientation of the PV plane of the

PV system was changed by altering the tilt angles
