A dairy farm located in Kitee, North Karelia, invested in 22+11 kWp photovoltaic system in June 2014. The system has been now operating two years and the experience has been positive. The annual production of 30 000 kWh is about 25% of the overall electricity consumption.
The PV investments have gained considerable interest among local farmers who often have the annual electricity consumption between 50 000 to 150 000 kWh, some even 350 000 kWh. Electricity consumption of cooling the milk down to 4 °C, as well as effective air-conditioning, require significant amount of electricity. On the other hand, farms usually have suitable sunny fields and roof surface areas for PV plants.
The local company, Mirotex ltd. has established system in Kitee together with technology supplier Green Energy Finland – the estimated payback times is below 8-9 years with 30% investment support. The PV plant was provided as a turnkey solution.
The farmer owning the system is very happy for his decision and emphasizes the benefits of having a local supplier and thus the service and maintenance easily available.
The established farm-scale plants have received considerable attention – new investments are planned and decided in other farms, housing associations and in industry/commerce. The Finnish GREBE partner, Karelia UAS, invests in demonstration PV plant.The investment is part of the Sirkkala Energy Park and will provide open-access information for all interested stakeholders.
