In this dissertation the key enablers, feasibility and potential yield for a photovoltaic system installed on an office building situated in Bergen is reviewed. The dissertation covers a broad area and seeks to discover potential benefits of such an initiative to a building owner. The paper focuses on the available incentives for the installation of a photovoltaic system on a commercial building.

The motivation has been to discover if the use of solar energy could be an attractive alternative to building owners seeking to reduce their energy usage.

It is found that a photovoltaic system installed on the roof could result in a better Energy Label and BREEAM NOR grade in the Norwegian context. The cost of such a system is competitive with conventional building methods. Such as extra insulation in the walls, three layer glasses with low U-values, lower Specific Fan Power (SFP) in air handling units and a more sealed building frame. There are however no governmental subsidies for the installation of photovoltaic systems in Norway.

PVsyst, software to calculate and design complete photovoltaic systems, was used to reveal the potential contribution of the proposed system. The available weather data and the results from PVsyst were considered as conservative. The cost of electricity from such a system was found to be almost twice as high as the retail price for electricity in Norway. When seen together with the alternative cost and the added revenue from rent increase, combined with a better Energy Label and BREEAM NOR grade, the use of photovoltaics is shown to be cost competitive.
