José Portillo, a farmer from Carmona, saw his earnings per hectare jump from €100 to €1,900 after leasing his land for a solar installation. His story highlights the financial impact of renewable energy projects on traditional agriculture in Andalusia.

When José Portillo agreed to lease 15 hectares of his farmland in Carmona, Seville, for a large-scale photovoltaic plant, he transformed his income overnight. Where he once grew wheat, sunflower seeds, and chickpeas, Portillo now receives €1,900 per hectare—far surpassing the €100 he previously earned from each harvest. This dramatic shift, first detailed in a 2023 broadcast of Equipo de Investigación, underscores the growing tension and opportunity as solar energy expands across rural Spain.

Portillo’s case is striking for its numbers: a 19-fold increase in declared income per hectare, from €1,500 to €28,500 for his 15 hectares. However, the figures should be read with caution. The original report did not specify whether these sums represent annual rents, and the terms of such contracts can vary widely depending on location, grid access, permits, contract length, and payment schedules. Landowners must also weigh gross rental income against the net profit from farming, considering taxes, land restoration, and what happens if a project fails to secure final approval.

Not every landowner is eager to make the switch. Decisions often hinge on more than just the highest offer. In Madrid, for example, one farmer turned down €700,000 to preserve his vegetable garden, as reported in a related case involving agricultural compensation. The diversity of responses reflects the complexity of rural land use as Spain accelerates its energy transition.

Changing Landscape

The story of Portillo’s land was revisited in August 2026, as Carmona continued to attract new solar projects. The BOJA, Andalusia’s official gazette, published fresh authorizations for installations like PSFV Carmona Energy, a 5 MW plant set to occupy plots in the area. The approval process itself can take years—PSFV Carmona Energy applied in August 2024, with construction only now moving forward. Yet, an authorization does not guarantee immediate operation; further licenses, construction, and commissioning are required before electricity flows to the grid.

Andalusia closed 2025 with nearly 11,700 MW of operational photovoltaic capacity and almost 198,000 self-consumption installations. While these numbers illustrate the region’s rapid solar expansion, they do not reveal how much farmland has shifted from crops to panels in Carmona. Some local estimates suggest a 20–30% drop in agricultural activity, but official statistics are lacking, and the true impact remains difficult to quantify.

Alternatives and Adaptation

Leasing all farmland to solar developers is not the only path. The Ministry for Ecological Transition (MITECO) promotes agrivoltaics—combining agriculture and solar generation on the same land. This approach uses elevated or spaced panels to allow continued cultivation, sometimes integrating beekeeping or aromatic plants, as seen in Carmona’s Las Corchas and Los Naranjos projects. However, agrivoltaics requires careful planning to balance shade, machinery access, and crop selection, and its economic viability depends on local conditions.

Other rural models are emerging as well. In Jaén, for instance, large-scale sheep grazing is used to manage vegetation and reduce wildfire risk, showing that land management strategies can be as diverse as the Spanish countryside itself.

Portillo’s experience highlights both the promise and the complexity of Spain’s solar boom. For some, the financial rewards are clear. For others, the decision to lease land or maintain traditional farming remains deeply personal, shaped by economics, identity, and the evolving landscape of rural life.
