Agrivoltaics With Trackers, Vertical Systems Offer Economic Upside
Mar 29, 2026
Agrivoltaics using tracking or vertical configurations can be financially viable and agriculturally beneficial when market revenues and land-use efficiency are considered, according to a new analysis by Jochen Hauff.
The argument responds to a study by Germany's Thünen-Institut that framed agri-PV as economically questionable due to additional costs of up to 148% compared with conventional ground-mounted systems. Hauff said that figure applies only to elevated systems used in specialized applications such as orchards, and does not reflect lower-cost configurations.
He also said the study focuses on the levelized cost of electricity without accounting for market value – the revenue solar electricity can earn depending on when it is generated. This omission can distort project economics, as investment decisions depend on both costs and expected revenues.
According to the Thünen study's own data, vertical agrivoltaic systems can have additional costs as low as 4%, while tracker-based systems show costs around 12% to 13% higher than standard ground-mounted plants. Tracker systems follow the sun throughout the day, while vertical systems produce more evenly in the morning and evening.
Hauff cited analysis by the Institute of Energy Economics at the University of Cologne (EWI), which found that tracker systems achieved a 43% higher market value than fixed south-facing installations in a modeled 2024 scenario in Brandenburg. A more even generation profile can also improve grid utilization and reduce peak loads.
The analysis argues that vertical systems, while offering smaller market value gains than trackers, benefit from lower additional costs, potentially making both configurations competitive with conventional solar when revenues are included.
Land-use efficiency is another key factor. According to the Thünen-Institut study, a standard ground-mounted solar plant can remove 1 hectare of agricultural land per unit of generation. Vertical agri-PV reduces this to 0.4 hectares, while tracker-based systems reduce it to 0.2 hectares, allowing 60% to 80% of land to remain in agricultural use.
Additional benefits cited include improved resilience against wind erosion, heavy rainfall, and excessive solar radiation, as well as better soil moisture retention.
Hauff concluded that agrivoltaics should be seen as a tool to strengthen both economic and physical resilience in rural areas, rather than a high-cost niche technology.
