Tiivistelmä
Agrivoltaics can combine solar photovoltaics generated electricity and agricultural production on the same land area. This thesis assesses the techno-economic feasibility of selected agrivoltaics configurations in Southeast Finland, with environmental considerations included as supporting background and future assessment needs.
The analysis compares horizontal single-axis tracking, interspace fixed-tilt, vertical east-west, and overhead fixed-tilt configurations against a ground-mounted photovoltaics system reference case. The scenario-based techno-economic model includes investment costs, operating costs, electricity generation, agricultural contribution, lease income, and land-use productivity. The economic indicators included are levelised cost of electricity, net present value, internal rate of return, discounted payback period, annual profitability indicators, and land equivalent ratio.
The results show that horizontal single-axis tracking is the strongest configuration under the stated assumptions, followed by interspace fixed-tilt. Vertical east-west remains technically relevant for Nordic conditions but has weaker economic performance and longer payback periods. Overhead fixed-tilt provides good access to agricultural operations, but it is not economically attractive from the developer perspective, even with the assessed investment grant. Overall, agrivoltaics can be techno-economically feasible in Southeast Finland under selected configurations and assumptions. Future work should pair the analysis with field validation, hourly electricity price modelling, more detailed agricultural modelling, and a full life cycle assessment, or an environmental impact assessment.
