Agrovoltaics lets you generate solar energy while maintaining agricultural activity beneath the panels — and keep collecting CAP subsidies.

Regulation (EU) 2021/2115, Art. 4.1.d establishes that it is indeed compatible if agricultural activity is maintained beneath the panels. Spain's MAPA published a clarifying note in 2023 confirming the eligibility of agrovoltaic installations for direct CAP payments. The key criteria are panel density (allowing genuine agricultural activity) and the maintenance of crops or grazing beneath the modules. SIGPAC must continue registering the surface as active agricultural land, and the farmer must be able to prove the dual production to the regional paying agency.

The permitting process combines RD 244/2019 on self-consumption and Law 24/2013 on the electricity sector with regional urban planning regulations. Three authorizations are required from the autonomous community: prior administrative authorization, construction authorization, and operating authorization. On rural land, a favorable urban planning report is also required under Art. 13 of the TRLS (RDLeg 7/2015), which regulates actions on rural land, plus the municipal building permit. For grid-connected installations over 100 kW, registration in the regional registry of electricity production facilities is mandatory, along with obtaining the access and connection point (PAC) from the relevant grid operator.

The IAE (Business Activity Tax) applies if installed capacity exceeds 100 kW (Law 39/1988 on Local Treasuries). Regarding the IBI (property tax), the installation may change the cadastral classification of the affected land from rural to urban, which would increase the cadastral value and the tax bill. However, the DGT in Ruling V2529-20 clarified that solar panels installed on rural land do not per se alter the cadastral classification if agricultural activity is maintained in a real and effective manner. It is advisable to consult the Land Registry (Catastro) before executing the installation to verify the applicable criteria for each specific property.

Yes. The Agri-Food PERTE and IDAE calls for proposals channel NextGenerationEU funds toward renewable self-consumption projects, including agrovoltaics. The PNIEC 2021-2030 sets a target of 39.2 GW of photovoltaic capacity for Spain. The autonomous communities have specific grant calls for self-consumption on agricultural holdings. Agrovoltaic projects are eligible if they demonstrate the dual function: electricity production and maintenance of agricultural activity on the same surface, which distinguishes them from pure photovoltaic parks on rural land.

RD 1183/2020 establishes a bond or guarantee of €2.5/kW for applications for access points to the electricity grid. Additionally, the autonomous communities require specific guarantees for the cost of restoring the land at the end of the installation's useful life (15-25 years). The estimated amount ranges between €5,000 and €50,000 per installation depending on size and region. A technical bond before the regional energy authority is the usual route, though some regions also accept civil liability insurance with dismantling coverage.

There is no general legal prohibition, since designations of origin have no regulatory authority over the urban planning use of land. However, each DO may include restrictions in its specifications document (Art. 102 of Law 24/2003 on vines and wine), which is the document governing accepted winemaking practices. The Regulatory Council of the corresponding DO should be consulted before installing, since some specifications require the vineyard to receive full sun exposure. Several DOs have approved specific protocols for vineyard agrovoltaics in recent years, verifying that the reduction in irradiation does not affect wine quality or the protected varietal characteristics.
