Short answer

Designers should focus on reducing the capital expenditure (CAPEX) of agrivoltaic systems and explore ways to increase revenue streams, either through enhanced grape yields/quality or more favourable energy pricing and self-consumption models.

Integrating photovoltaic systems into vineyards, known as agrivoltaics, is currently not economically feasible in Germany due to high initial costs and insufficient combined revenue from grape and energy production. This resource management research insight is drawn from a 2024 study published in Frontiers in Horticulture. Using Simulation and scenario analysis, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should focus on reducing the capital expenditure (CAPEX) of agrivoltaic systems and explore ways to increase revenue streams, either through enhanced grape yields/quality or more favourable energy pricing and self-consumption models.

Agrivoltaic Systems in Vineyards Show Negative Economic Viability Under Current German Conditions

Integrating photovoltaic systems into vineyards, known as agrivoltaics, is currently not economically feasible in Germany due to high initial costs and insufficient combined revenue from grape and energy production.

Key Findings

  • 01Under current conditions in Germany, agrivoltaic systems (AVS) are not economically viable for widespread adoption.
  • 02High initial costs (CAPEX) and insufficient revenue from combined grape and energy production lead to negative net present values over a 20-year period across all simulated scenarios.
  • 03CAPEX and energy prices are critical factors for profitability, while viticulture-related costs and revenues have a minor impact.
  • 04Scenarios incorporating multiple positive changes (e.g., premium wine pricing, higher feed-in tariffs, increased self-consumption) show potential for economic feasibility.

Application

Design takeaway

Designers should focus on reducing the capital expenditure (CAPEX) of agrivoltaic systems and explore ways to increase revenue streams, either through enhanced grape yields/quality or more favourable energy pricing and self-consumption models.

How to apply

When designing integrated systems, conduct thorough economic feasibility studies that account for all capital and operational expenditures, as well as potential revenue streams from all outputs. Consider policy and market incentives that could improve economic viability.

Project actions

  • 01When evaluating a new technology, always consider its economic feasibility alongside its environmental and functional benefits.
  • 02Research current market prices for both the primary product (e.g., grapes) and the secondary product (e.g., electricity) to build realistic revenue models.

Method & Evidence

AimTo develop a framework for assessing the economic performance of agrivoltaic systems in vineyards and to identify factors influencing their profitability.
MethodSimulation and Scenario Analysis
ProcedureA framework was developed to classify factors influencing the profitability of integrating photovoltaic (PV) systems with viticultural practices. This framework was operationalized by simulating various scenarios based on key variables such as capital expenditures (CAPEX), operational expenditures (OPEX), and revenue streams from grape and energy production, considering factors like solar radiation, panel transparency, and regulatory impacts.

Strengths & Limitations

Strengths

  • +Development of a comprehensive framework for economic assessment.
  • +Simulation of multiple realistic scenarios to explore a range of conditions.

Limitations

The economic model used might not capture all real-world variables, such as unpredictable weather impacts on grape yield or fluctuating energy market dynamics.

Reliability & validity

The reliability of the findings depends on the accuracy of the input data for CAPEX, OPEX, and revenue streams, as well as the assumptions made in the simulation models. Validity is enhanced by considering multiple influencing factors and simulating various scenarios.

Think critically

Given that agrivoltaics are not currently economically viable in this context, what alternative strategies or policy interventions could be proposed to bridge the gap between environmental benefits and financial sustainability?

05

Design Principles

"Economic viability is a critical determinant for the successful adoption of integrated sustainable technologies."

This research highlights a critical economic barrier for a promising sustainable technology. Designers and engineers need to understand these financial constraints to develop more cost-effective solutions or to advocate for policy changes that support the adoption of agrivoltaic systems.

06

What This Means for Your Design

Putting solar panels on farms, like vineyards, is a good idea for the environment, but right now, it costs too much money in Germany to be worth it. The cost of setting it up is high, and you don't make enough from selling grapes and electricity to cover it. Things would need to change with prices and government support for it to make financial sense.

How to use in your project

  • 1.Use the findings to justify the need for cost-effective design solutions in your own design project, especially if it involves integrated systems or renewable energy.

Paragraph starter

The economic performance of integrated systems, such as agrivoltaics in vineyards, is a critical factor for their widespread adoption. Research indicates that under current market and regulatory conditions in Germany, these systems face significant economic challenges, primarily due to high capital expenditures and insufficient combined revenue streams, leading to negative net present values over a typical project lifecycle.
