What Is Agri-PV? The 2026 Guide to Technology, Funding, and Economic Viability

Agri-PV combines agriculture and solar power on the same plot of land. This guide explains to B2B decision-makers and investors how agri-photovoltaics is defined under DIN SPEC 91434, what types of systems are available, what the EEG feed-in tariff will look like in 2026, how much an agri-PV system costs, and what return on investment is realistic—with each figure accompanied by its primary source and current status.

What is agri-PV, and why is its land efficiency increasing to over 160 percent?

In short: Agri-PV makes dual use of the same land: Solar modules are mounted on racks above or vertically between the crops, while cultivation continues underneath. The effect is measured by the Land Equivalent Ratio (LER). The Fraunhofer ISE facility in Heggelbach achieved 160 percent in the normal year of 2017 and 186 percent in the drought year of 2018—one hectare yields the output of up to 1.86 hectares.

The Land Equivalent Ratio (LER) describes how much land would be needed if used separately to achieve the same total yield from electricity and crops. Values above 100 percent indicate a gain in land efficiency resulting from the combination. Fraunhofer ISE estimates the LER of its reference systems to be between 1.6 and 1.86 (Fraunhofer ISE, Agri-Photovoltaics Guide). This dual harvest of solar power and crops significantly increases land use efficiency without displacing agriculture.

‍ ‍

The benefit increases during dry years: partial shading reduces evaporation at ground level and alleviates heat stress on the plants. In Heggelbach, the potato yield in 2018 was 11 percent higher than the open-field reference (Trommsdorff et al. 2021). In this way, agri-PV addresses the competition for land between energy and food production caused by conventional open-field solar power systems.

Definition and legal framework according to DIN SPEC 91434

In short: DIN SPEC 91434:2021-05 provides a binding definition of agri-PV. Category I consists of high-rise systems with a minimum clearance height of 2.10 meters and a maximum land loss of 10 percent. Category II includes ground-level and vertical systems with a maximum land loss of 15 percent. In both cases, the land must retain at least 66 percent of its agricultural reference yield—otherwise, it is not considered Agri-PV.

DIN SPEC 91434 specifies the minimum requirements for primary agricultural use—food production takes precedence over solar power generation. The key difference from traditional ground-mounted photovoltaic systems is the land status: With agri-PV, the land remains agricultural or forestry property and is assessed under Property Tax Category A; a purely ground-mounted system converts it into real estate subject to Property Tax Category B (state decrees of July 15, 2022). CAP direct payments are also maintained at 85 to 90 percent of the land area (Section 12 of the CAP Direct Payments Regulation). Since 2024, DIN SPEC 91492:2024-06 has supplemented the standard with requirements for livestock farming under agri-PV.

What Types of Designs and Agri-PV Technologies Are Available?

In short: Four design types dominate. High-rise systems (Category I) installed above orchards, vineyards, and hop fields deliver 500 to 700 kWp per hectare. Vertical bifacial PV modules based on the Next2Sun principle (Category II) are suitable for grassland and arable farming. In addition, there are tracking systems and translucent glass-glass modules. Depending on the design, investment costs range from 700 to 1,700 euros per kWp.

Elevated agri-PV systems are installed with a minimum clearance of 2.10 meters above the crops, allowing even large agricultural machinery to operate underneath them. They are suitable for perennial crops such as fruit, berries, grapes, and hops, while also providing these crops with protection from hail, frost, and intense sunlight. Light-transmitting or semi-transparent PV modules precisely control the amount of light the crops receive.

Tracking systems optimize solar power production by allowing the PV modules to follow the sun’s path; this increases yield and market value, but incurs additional costs. For light-demanding crops such as grains, agri-PV systems with wider spacing between modules are necessary. Vertical agri-PV based on the Next2Sun principle arranges bifacial PV modules vertically in rows and generates its solar power primarily in the morning and evening, which smooths out the feed-in profile.

EEG Feed-in Tariffs for 2026 and BNetzA Tenders for Agri-PV

In short: Small agri-PV systems up to 1 MW receive a base rate of 6.59 ct/kWh (fixed feed-in tariff of 6.19 ct/kWh) plus a 0.5 ct/kWh technology bonus for high-mounted systems—approximately 7.09 ct/kWh. Larger systems are eligible for the “special solar systems” tender, which offers a maximum rate of 9.5 ct/kWh and a bonus of 2.5 ct/kWh—both subject to EU state aid approval.

Agri-PV is defined in the EEG 2023 as a “special solar installation” under Section 48(1), first sentence, No. 5 (arable land, permanent crops, permanent grassland). For systems up to 1 MW, the statutory reference value of 6.59 ct/kWh applies; the fixed feed-in tariff is 6.19 ct/kWh (Section 48(1), Section 49 EEG 2023; Bavarian State Office for Agriculture, as of January 31, 2026). Rates have been in effect since August 1, 2026; the next reduction will take effect on February 1, 2027; as of August 1, 2026.

‍ ‍

Larger agri-PV systems are covered by the tender for special solar installations. The maximum rate is 9.5 ct/kWh (Section 37b(2) EEG 2023), plus a bonus of 2.5 ct/kWh (Section 48(1b) EEG 2023). Both figures are derived from Solar Package I and are subject to approval under EU state aid law, which had not yet been granted as of January 31, 2026. This sub-segment will have a capacity of 1,200 MW in 2026 (Section 37d EEG 2023). The articles on “Agri-PV Open-Field Investment 2026” and “Agri-PV Italy for Investors” provide further insight into the investment outlook.

Building Regulations, Land Status, and Taxes

In short: Since the Solar Package I, farm-based agri-PV systems of up to 2.5 hectares in rural areas have been granted special status (Section 35(1)(9) of the German Building Code (BauGB))—no zoning plan is required. The land remains agricultural property subject to property tax class A, and CAP direct payments are maintained at 85 to 90 percent. For commercial systems, the investment deduction under § 7g of the Income Tax Act (EStG) applies.

The special provisions under Section 35(1)(9) of the German Building Code (BauGB) apply to facilities associated with an agricultural operation of up to 2.5 hectares. Larger projects still require a zoning plan or fall under the land-use framework of the Renewable Energy Sources Act (EEG).

‍ ‍

For tax purposes, the tax authorities treat agri-PV as agricultural and forestry assets—with benefits regarding property tax, inheritance tax, and real estate transfer tax. For commercial operators, the investment deduction under Section 7g of the Income Tax Act (EStG) is also relevant; the guide to the investment deduction for photovoltaics explains how this interacts with the PV tax exemption.

How Much an Agri-PV System Costs and What Return on Investment Is Realistic

In short: The investment costs for agri-PV range from about 900 to 1,700 euros per kWp for systems ranging from 0.5 to 2 MWp (Fraunhofer ISE)—higher than for ground-mounted systems due to the more complex substructure. In the Helm Group’s portfolio, the rate of return typically ranges from 7 to 8 percent per annum (portfolio data for 2024). Return figures are not a guarantee of future results.

The range of investment costs depends heavily on the design: High-mount Category I systems are at the upper end of the range at 1,500 to 1,700 euros per kWp, while vertical bifacial systems are significantly lower at 700 to 1,000 euros per kWp. Higher mounting structures, greater module spacing, and, in some cases, tracking systems account for the higher cost compared to a standard ground-mounted system.

‍ ‍

For landowners, the lease is the key lever. For dual-use agri-PV projects in Germany, it ranges from 1,000 to 3,500 euros per hectare per year (Logic Energy / Helm Group, portfolio data for 2024). The page on leasing land for solar parks provides details on the complete lease models, contract clauses, and the process.

Which crops are compatible with agri-PV

In short: Shade-tolerant perennial and specialty crops are best suited. Apples, berries, hops, and grapes actually benefit from protection against hail, frost, and UV rays when grown under high-elevation structures. Grassland and clover-grass mixtures are well-suited to vertical systems. Potatoes and winter wheat range from acceptable to good, depending on the year. Tall, light-demanding crops such as corn and sunflowers are not suitable.

To date, agri-PV has been most widely adopted in fruit and grape cultivation as well as in berry farming, where the modules provide additional protection for high-value crops. The impact on yield depends on the crop, the year, and the design. In Heggelbach in 2018, celery yields were 12 percent higher than the open-field reference; potato yields ranged from −20 percent in a normal year to +11 percent in a drought year (Weselek et al. 2021). For many farms, the predictable income from electricity generation offsets slight yield losses.

Seven Synergies for Agriculture

In short: Agri-PV offers more than just electricity: partial shading reduces heat and drought stress, elevated modules provide protection against hail and frost, and evaporation is reduced. In addition, it provides a second, weather-independent source of income from electricity sales, protection against erosion caused by heavy rain, improved animal welfare conditions for grazing livestock, and a contribution to biodiversity through extensive maintenance under the modules.

The strongest agronomic effect is evident in extreme years. Because the modules reduce evaporation and moderate crop temperature, yield losses in 2018 were lower than in a normal year—for some crops, the effect even resulted in a net gain. Preliminary one-year results from the LfL demonstration facility in Grub showed up to 10 percent higher yields for spring barley (TFZ Straubing / LfL Bavaria, April 2025).

This creates a win-win situation: Farmers secure their harvests while also generating solar power—a contribution to climate protection and the energy transition that optimizes land use and can be combined with extensive land management and nature conservation beneath the solar panels.

Market Potential in Germany and Seven Pilot Plants

In short: Fraunhofer ISE estimates the technical potential for agri-PV in Germany at around 1,700 GWp; converting just 4 percent of arable land would already cover a large portion of the solar target. The EEG caps PV on agricultural land at 80 GW by 2030 (Section 37(4) EEG 2023). Seven reference projects demonstrate the transition from the pilot phase to the market phase.

Seven reference projects mark the transition from the pilot phase to the market phase—from the Fraunhofer ISE Heggelbach plant (2016) to the 4.3 MWp vertical bifacial solar park in Löffingen (2024). The range extends from 194 kWp through mixed-crop systems to multi-megawatt installations on grassland and arable land with cattle farming.

Agri-PV Research and Model Regions

This development is being driven by agri-PV research. The Fraunhofer Institute for Solar Energy Systems ISE built the Heggelbach research facility, Germany’s first large-scale pilot plant; the Baden-Württemberg Agri-PV Model Region is testing various agri-PV systems and crops at multiple locations; and the Bavarian State Research Institute for Agriculture (LfL Bayern) is comparing three system types at the Grub demonstration facility. This research provides the reliable yield and land-use data on which planning and economic viability are based.

International Comparison: Japan, France, Italy

In short: Japan is considered a pioneer, with approximately 300 MW installed across some 2,000 farms. France has regulated agri-PV since 2024 under Decree 2024-318 and pays 2,000 to 5,000 euros per hectare of leased land. Italy supports agrivoltaics through the PNRR program with capital grants of up to 40 percent and a feed-in tariff—making it a particularly attractive market for investors.

Specific subsidy programs are driving expansion: While Germany regulates agri-PV through the EEG and land-use privileges, Italy offers a direct capital grant under Decree DM 436/2023. The Italian market is therefore of particular interest to investors; details, subsidy amounts, and deadlines are covered in the guide “Agri-PV in Italy as an Investment.”

Limitations and Valid Criticism of Agri-PV

In short: Agri-PV is not a sure thing. The investment costs are higher than for ground-mounted systems, and elevated systems are primarily cost-effective for high-value specialty crops. Not every crop can tolerate partial shading, the use of large machinery is limited, and the profit-boosting incentives are subject to EU state aid regulations.

The higher support structure and wider module spacing reduce the installable capacity per hectare compared to ground-mounted systems and increase the specific costs. As a result, profitability depends more heavily on the location, the crop, and the allocation of subsidies. As long as approval under subsidy regulations for the bonuses is pending, part of the calculation remains subject to uncertainty—a point that sound planning takes into account.

Agri-PV 2026–2030: EEG Amendment, CfD, and Solar Package II

In short: The regulatory framework remains in flux. The semi-annual de-escalation continues to reduce feed-in tariffs, and starting in 2027, new installations will be subject to a direct marketing requirement and the transition to Contracts for Difference (CfDs). The Agri-PV bonuses, which impact returns, are still awaiting EU state aid approval. Investors should review the regulatory status again shortly before the project begins.

For investors looking ahead to the upcoming CfD requirement, the article “The 2027 CfD Requirement for PV Investors” summarizes the implications of the transition. The guide addresses the basic logic behind returns, terms, and the direct investment structure to help determine whether photovoltaics are a worthwhile investment.

FAQ

What is agri-PV, explained simply?

Agri-PV is a solar power system that uses agricultural land for both electricity generation and crop cultivation. The modules are mounted on supports above or vertically between the crops, so that both the harvest and solar power are produced on the same field (DIN SPEC 91434:2021-05).

How much rent does a farmer receive for agri-PV?

For dual-use agri-PV, the lease rate in Germany ranges from 1,000 to 3,500 euros per hectare per year (Logic Energy / Helm Group, 2024 portfolio data). The exact amount depends on the location, grid connection, and design.

What will the EEG feed-in tariff for agri-PV be in 2026?

Systems up to 1 MW receive a base rate of 6.59 ct/kWh plus a 0.5 ct/kWh technology bonus, for a total of approximately 7.09 ct/kWh (Sections 48 and 38b of the EEG 2023; as of January 31, 2026). Larger plants can offer up to 9.5 ct/kWh through the tender process, subject to EU state aid approval. The next rate reduction takes effect on August 1, 2026.

Will the land retain its agricultural status under agri-PV?

Yes. In the case of Agri-PV systems that comply with DIN SPEC 91434, the land remains agricultural and forestry property subject to property tax class A, and CAP direct payments are maintained at 85 to 90 percent (state decrees of July 15, 2022; § 12 GAPDZV).

Which crops are suitable for agri-PV?

The most shade-tolerant perennial and specialty crops—such as apples, berries, hops, and grapes—benefit from protection against hail and frost, while grasslands are well-suited to vertical systems. Tall, light-demanding crops such as corn and sunflowers are not suitable (Weselek et al. 2021).

What is the difference between Category I and Category II?

Category I consists of elevated systems with a clear height of at least 2.10 meters and a maximum loss of area of 10 percent. Category II includes ground-level and vertical systems with a maximum loss of area of 15 percent (DIN SPEC 91434:2021-05, Section 4).

Does agri-PV require a zoning plan?

Farm-adjacent facilities up to 2.5 hectares are given preferential treatment in rural areas and do not require a zoning plan (Section 35(1)(9) of the German Building Code (BauGB)). Larger projects are subject to a zoning plan or the EEG land-use framework.
