Feasibility study for utilization of solar energy in the arctic areas

Abstract

This research investigates a solar thermal system and a solar photovoltaic system which produces local energy, by incoming solar radiation, to meet the energy consumption demand of a residential building in the arctic region. The study on the use of the solar systems in the arctic areas is rare and often doubted. So, to analyze the potential of solar energy, a study case of an existing building block in Narvik, Norway was selected. The performance and function of both the systems were studied and achieved by calculation and simulation models of the thermal system and the PV system separately. The solar systems met the energy demand of <i>DHW and space heating</i> during summer due to the availability of the sun for long hours. However, in winter, especially in December and January, the energy production was zero due to snow accumulation and minimum sunlight. The results showed that the solar thermal collector produced about 14315 kWh throughout a year, whereas, the PV system generated an annual energy output of 18640 kWh. Thus, the results suggest considerable potential for solar utilization, however in the current context cost can be a limitation.
