The Structural Question Behind Dual-Income Models

In a conventional ground-lease solar arrangement on agricultural land, the energy developer leases the land entirely, and the landowner receives a fixed annual fee. Agricultural activity typically ceases for the lease duration, often 20–30 years. The trade-off is straightforward: steady, predictable income in exchange for lost farming revenue and potential complications when the land is returned.

Agrivoltaic configurations create a structurally different arrangement. The land continues to produce crops — either farmed by the original operator or leased separately to an agricultural tenant — while also hosting an energy installation. This creates the possibility of two income streams from the same parcel but also introduces contractual and management complexity that standard land leases do not address.

Ground Lease Structures in Italian Agrivoltaic Projects

Italian agrivoltaic lease arrangements have not yet settled into a single standard form. Several models have appeared in publicly documented projects:

Energy Lease with Agricultural Sub-License

The energy developer holds a primary lease on the land, giving it rights to install and operate panels. It then grants the original landowner or a third agricultural operator a sub-license to farm the land beneath and between the panels, subject to operational constraints (no activity conflicting with panel maintenance, access requirements, etc.). Rental income to the landowner comes from the energy developer; agricultural sub-license fees, if any, are a secondary consideration.

Landowner-Retained Agricultural Operation

The landowner retains the right to farm the land directly in a lease that explicitly carves out agricultural use. The energy developer's lease covers only the airspace and supporting structure, not the soil surface. This model is conceptually cleaner from an agricultural continuity standpoint but requires precise drafting to define the physical boundaries of each party's rights.

Joint Venture Structure

In some documented cases, particularly where landowners hold larger parcels and have investment capacity, a joint venture between landowner and energy developer captures a share of energy revenues rather than a flat lease rate. Revenue sharing may be tied to energy production output, making the landowner's income variable but potentially higher over a productive installation's life.

Italian contract law (Codice Civile) governs land leases (affitto di fondi rustici) under Articles 1615–1654 for agricultural leases specifically. Agrivoltaic arrangements may not fit neatly into these provisions and are sometimes structured as commercial (not agricultural) leases to avoid restrictions on duration and termination that apply to agricultural lease categories.

Cadastral Classification and Its Practical Consequences

The Italian cadastral system classifies land into categories that determine both land registry valuation (rendita catastale) and applicable tax treatment. Agricultural land (terreno agricolo) benefits from favourable tax treatment under several Italian tax provisions. The concern for landowners entering agrivoltaic arrangements is whether the installation triggers a reclassification to a different cadastral category, with implications for:

  • IMU (Imposta Municipale Unica — municipal property tax): rates differ significantly between agricultural and commercial classifications
  • Capital gains treatment if the land is later sold
  • IRPEF agricultural income exemptions available to smallholders
  • Access to EU agricultural subsidies (PAC — Politica Agricola Comune), which require the land to be maintained in agricultural use

The Agenzia delle Entrate has issued guidance on the cadastral treatment of photovoltaic installations and has taken positions on when solar arrays attached to agricultural land create a new cadastral unit. Agrivoltaic configurations, where agricultural use continues, occupy an ambiguous position in these interpretations. Landowners should verify in writing with their local Agenzia delle Entrate — Territorio office before committing to a lease structure that affects cadastral status.

EU Common Agricultural Policy Subsidy Compatibility

Farmland in Italy receiving CAP direct payments (pagamenti diretti) under the new CAP 2023–2027 framework must meet eligibility conditions including maintaining the land in agricultural use. The question of whether agrivoltaic panel coverage affects parcel eligibility for CAP payments is handled through the national payment agency (AGEA — Agenzia per le Erogazioni in Agricoltura) and the regional implementation bodies.

Italy's CAP national strategic plan addresses agrivoltaic compatibility to some extent, distinguishing between panel coverage that effectively removes land from agricultural production and configurations where genuine agricultural activity continues. However, the practical application at parcel level through the SIAN (Sistema Informativo Agricolo Nazionale) mapping system has encountered inconsistencies, with some agrivoltaic parcels facing reduced eligible area determinations in regional inspections.

Land Fragmentation and Parcel Assembly Challenges

Italian agricultural land is characterised by significant fragmentation, particularly in central and southern regions. Individual parcels of less than a hectare are common, and agrivoltaic installations of meaningful scale typically require aggregating multiple contiguous parcels — which may be held by different owners or subject to agricultural tenancy rights that predate any agrivoltaic interest.

Pre-existing agricultural leases (affitti agrari) can complicate the assembly process. Under Italian law, agricultural tenants hold certain protections including the right of first refusal on sale (prelazione agraria) and limits on early termination. Energy developers seeking to install agrivoltaic systems on leased agricultural land must account for existing tenant rights before lease structures can be finalised.

Consideration Relevant Authority / Framework Key Risk
Cadastral classification change Agenzia delle Entrate — Territorio Higher IMU rates, loss of agricultural tax treatment
CAP subsidy eligibility AGEA / regional payment bodies Reduced eligible area, subsidy recovery demands
Existing tenant rights Codice Civile, L. 203/1982 Inability to modify land use without tenant agreement
Lease classification (agricultural vs commercial) Codice Civile, regional courts Application of mandatory agricultural lease protections

Income Visibility and Long-Term Land Use Planning

From a farm management perspective, the dual-income model requires that both revenue streams remain viable over the installation's life — typically 25–30 years. Agricultural income depends on continuing crop viability under the installation geometry, market prices, and input costs. Energy income depends on panel performance, grid connection costs, and the regulatory environment for energy feed-in or self-consumption over the contract period.

Long-term land use plans in Italian rural municipalities (Piani Strutturali Comunali or PRG) may also constrain how the parcel can be used when the energy lease expires. Some municipalities have begun incorporating provisions about land restoration obligations for solar installations into local planning instruments, a development that affects how landowners should think about lease end-of-life terms.

Italian farm advisory bodies — including Coldiretti, Confagricoltura, and CIA (Confederazione Italiana Agricoltori) — have published position papers on agrivoltaic arrangements. These documents, while advocacy-oriented, contain summaries of common contractual issues encountered by their member farmers and are freely available on their respective websites.

Points That Remain Unsettled

As agrivoltaic installations in Italy move beyond pilot projects toward commercial scale, several land-use questions remain without definitive resolution: the precise cadastral treatment of above-ground panel structures on otherwise agricultural land; the interaction between agrivoltaic leases and agricultural succession rights; and how regional land-use plans will classify parcels hosting agrivoltaic installations when plan revisions are next carried out.

The regulatory and contractual landscape is developing, and positions taken in early agrivoltaic leases may not reflect how courts or administrative bodies interpret disputes that arise later. Professional advice from agricultural law specialists familiar with both energy sector contracts and Italian agrarian law provisions is appropriate before commitments are made.
