A solar PV system was installed on the rooftop of Križevci’s Development Center and Technology Park’s administrative building.
The Green Energy Cooperative provided solar equipment for lease to the city of Križevci, the owner of the building, for 10 years. All investors signed a loan agreement with the Cooperative for 10 years as well, for which an annual interest on accrued funds was projected. The modelled system (50 kW), installed on the rooftop of the business centre, primarily covered the needs of the users of the centre in terms of electricity. The city paid the actual electricity consumption, and from the monthly savings, it returned investment to citizen-investors. The energy surplus was sold to the network. After 10 years (required for the investment to pay off) the system was transferred into the city’s ownership and continued to make savings.
The Green Energy Cooperative is led by the partners from the city of Križevci, Regional Energy Agency North, Greenpeace Croatia, Solvis and ACT Group.
The municipality of Križevci provided administrative and financial support in the preparation phase and grants an energy-saving fee for 10 years to investors. The Green Energy Cooperative has provided the solar equipment on lease to the city for 10 years. The Regional Energy Agency North developed a cost-effectiveness analysis and the general design documentation. Solvis, a PV module producer from Croatia, installed the PV plant on the rooftop.
