PV systems on the apartment buildings of Uppsalahem : Economic potential until 2030 (English)
Abstract [en]

Uppsalahem is the leading housing corporation in Uppsala with its over 160 real estate properties. Uppsalahem is owned by the municipality of Uppsala, which has a climate and energy goal that aims for 100 MW of solar energy to be installed in Uppsala by 2030. The 100 MW goal, combined with Uppsalahem’s environmental policy, is a strong incentive to investigate the possibility of installing PV modules on the many available roof areas that Uppsalahem possesses. The objective of this thesis is to create a foundation for future decisions regarding PV systems for Uppsalahem. The economic potential for PV systems on apartment buildings until 2030 was therefore calculated. The calculations were made in a computer model created in Matlab that can be used by Uppsalahem for future decision-making.

Uppsalahem owns a 2,0 MWp wind power plant that is expected to supply 35 % of the total electricity use of the corporation. The electricity produced in the plant is tax exempt, under the condition that no electricity, including PV produced electricity, is sold by Uppsalahem. As any surplus electricity cannot be sold, the profitability of all PV installations is determined largely by the electricity use of each building.

The economic PV potential was calculated for 11 scenarios starting from a base scenario that was based on the parameters deemed most likely to be true. In the base scenario, where no electricity certificates or investment support were used, the potential was 0,30 MWp 2015 and 1,59 MWp 2030. If electricity certificates or investment support is used, the potential in 2015 is 1,13 and 1,64 MWp, respectively. For 2030 the potential increases to 1,90 and 2,10 MWp. In the base scenario, PV installations can supply 1,4 % of Uppsalahem’s annual electricity use in 2015 and in 2030 1,6 % of the 100 MW goal can be met by Uppsalahem.
