However, with the proliferation of utility-scale photovoltaic plants, land use competition with other social and economic activities is becoming an issue. As a result, interest in implementing structure-integrated PV systems is increasing, as these are seen as a way to minimize the PV-occupied land area. This study evaluates the technical and economic performance of a photovoltaic system integrated into a vertical barrier in Sines, Portugal, and assesses its potential contribution to the decarbonization of the energy sector.

The REC includes an AgriPV power plant with two different configurations, overhead and interspatial with a total capacity of 175 kW, located at the university campus in Nossa Senhora de Tourega. The community encloses the university campus and the neighbouring village of Valverde. The daily energy production profiles of two AgriPV plant configurations are analysed, for a winter and a summer day. These profiles are compared with the consumption profiles of the university campus, and an average household in Évora, and the strategies to maximize the energy community self-consumption are discussed. The main difficulties and advantages of managing agricultural activities and selling agricultural products in the energy community are also examined.

This paper systematically reviews sensors and monitoring strategies deployed in FPV systems, distinguishing itself from prior work by mapping sensor configurations to specific monitoring goals (e.g., environmental, energy performance, structural or ecological) and highlighting gaps in power autonomy, calibration, and integration. To evaluate sensor types, measured variables, and data handling protocols, 118 experimental studies were analyzed and recommendations to improve reproducibility and standardization are provided.

Agrivoltaics systems can be one of the strategies to accomplish this goal. These systems allow the combination of food and energy production in the same space in a synergistic way, avoiding land-use competition between PV and agriculture. This study analyzes the technical potential of agrivoltaics in mainland Portugal, a country particularly suitable for its implementation due to its high solar potential and diversified agriculture. The study used public geographic information system databases to perform systematic mapping of the viable areas. The methodology used was based on a multicriteria geospatial analysis, which included the identification of agricultural and pasture areas (based on the 2023 Land Use Charter), the exclusion of zones with legal restrictions such as National Agricultural Reserve (RAN), National Ecological Reserve (REN), and Natura 2000 Network, and the areas with a terrain slope >10%. The analysis revealed that the Alentejo region has the greatest technical potential, due to its predominantly flat topography, high solar radiation, and low density of environmental restrictions. The study estimated the potential for installed photovoltaic (PV) power through overhead configuration. Sat, 01 Nov 2025 00:00:00 GMT http://hdl.handle.net/10174/42203 2025-11-01T00:00:00Z
