Vertical farming and agrivoltaics can complement each other to create a more resilient, resource-efficient agricultural model. Vertical farming maximizes production by stacking crops in controlled indoor environments, potentially multiplying the effective growing area several times within the same footprint. However, artificial lighting, HVAC systems, and automation can generate substantial electricity costs. Agrivoltaics offers a complementary solution by integrating photovoltaic generation with outdoor agricultural production, while rooftop solar and elevated PV canopies supply renewable electricity to indoor facilities. In the infographic’s illustrative 1,000 m² case study, 150 m² of indoor space with five growing tiers provides approximately 450 m² of effective cultivation surface, demonstrating how spatial efficiency can increase without expanding the land footprint.
The real opportunity lies in integrated energy and resource management. The proposed system combines 55–75 kWp of installed solar capacity with an estimated annual PV generation of 60.5–135 MWh, alongside an indoor LED lighting demand of approximately 210 MWh per year. These figures illustrate both the potential and the limitations of solar integration: photovoltaic generation can offset a meaningful share of electricity consumption, but grid electricity or additional storage and generation may still be necessary, particularly when lighting demand extends into the evening. Smart load-shifting, automated irrigation, efficient LED technology, water recirculation, and rainwater harvesting can further improve operational performance. Importantly, the infographic’s energy estimates are scenario-dependent and should be validated through hourly simulations, local solar irradiation data, equipment specifications, and seasonal operating profiles before investment decisions are made.
From an investment perspective, the combination creates opportunities to diversify revenue through outdoor crops, year-round indoor production, seedlings, high-value herbs, and potentially greater self-consumption of renewable electricity. For semi-arid regions such as Northeast Brazil, where water scarcity, heat stress, and land productivity are major challenges, integrating solar generation with controlled-environment agriculture could support a more efficient use of both land and water.
Nevertheless, success depends on crop selection, capital expenditure, electricity tariffs, cooling requirements, water availability, and the local market for premium produce. The strategic objective is not simply to install more solar panels or grow more crops vertically; it is to design an integrated system.
