During the First Andalusian Congress on Agriculture, Energy and Water held at the University of Almería, a path that begins to materialize today was already glimpsed. In that meeting, Professor Ángel Carreño He stressed that the use of photovoltaic plates In greenhouses, intensive agriculture could revolutionize. “With just 1% shadow with solar panels on the roof, the energy needs of a greenhouse could be covered,” he said.
Seven years later, this forecast is specified in a pioneering project that aims to make a qualitative leap to the Almeria agricultural model: Dynamic Aquasave.
From the plastic sea to the energy sea. The scenario of this innovation cannot be more unique. NASA confirms that the “plastic sea” Almeria is one of the few human constructions visible from space. According to the BBCunder its 32,000 hectares of white plastic, about four million tons of foods are produced every year to export them to Europe, generating about 5.1 billion dollars annually, which represents 40% of the GDP of the province.
It is in this context where Dynamic Aquasave arises, with the promise that the plastic sea can be transformed into an energy sea, capable of producing not only food, but also electricity.
How will it be? The University of Almería, together with Barre greenhouses, the Technalia Technology Center, the Uual-Anecoop Foundation and with CDTI financing, leads this project. The contract was signed in November 2024 and was ratified in February 2025 In the official act of the Department of Engineering of the UAL.
The system consists of installing transparent or semi -transparent solar panels on the greenhouse cover, which are automatically oriented thanks to an algorithm. These panels fulfill a double function: they act as a dynamic shade to control excessive radiation and, at the same time, generate electricity.
As He explained Professor Diego Luis Valera to Diario de Almería, “integrates, in the same system, photovoltaic generation and dynamic shadow governed by algorithms, something that does not exist in the market with the parameters required by a greenhouse adapted to the southeast of Spain.” The planned benefits are clear: up to 30% water savings, less needy need, a more stable microclimate, energy for self -consumption or sale and better working conditions within greenhouses.
Forecasts The Dynamic Aquasave prototype will be installed at the Uual-Anecoop Foundation, where a greenhouse will also be enabled to compare yields. The experimentation phase is scheduled for the fall of 2025 and will last at least two agricultural campaigns.
The project also has the collaboration of the University of Córdoba, which develops specific software and hardware for the control of the orientable panels. The combination of agricultural engineering, artificial intelligence and renewable energy makes it a unique proposal in the international scene.
The digital layer. Dynamic Aquasave is not just solar energy. According to has detailed Valera to Diario de Almería, also seeks to provide the field of an artificial intelligence layer. With sensors and automatic learning algorithms, the system can predict dates and kilos of harvest before cutting, adjusting irrigation and nutrient supply in real time, and reducing the water and carbon footprint.
In addition, the equipment works in passive microclimate systems: low -cost solutions that allow regulating temperature and humidity without spending energy, favoring biological pest control and reducing inputs. The project also supports international research and transfer networks, which seek that these innovations do not stay in laboratories, but arrive as soon as possible to real farms.
Although the problems are not going to go. The European garden also drags criticism. Technology can relieve some challenges, but not solve them all. No algorithm can, by itself, reverse the overexploitation of aquifers or the social problems of the Almeria field.
On the one hand, academic investigations cited by the British environment They remember that growth has been sustained thanks to the overexploitation of underground aquifers, some in deficit for more than two decades, and that 30,000 tons of plastic waste are generated every year. On the other hand, The newspaper El Salto The other face denounces: migrant workers living in precarious settlements, with low salaries and marathon days. Although Dynamic Aquasave represents a technological leap, but the Almeria model also needs to face its social and environmental side.
A challenge beyond energy. Although We have already explained in Xataka As solar panels can be an improvement for crops, the challenge, however, goes beyond engineering. The key will be that the plastic sea not only becomes a sea of solar panels, but an agricultural space that combines innovation with social justice and environmental sustainability. Only then, Almería may go from being a green miracle to become a world agriculture model of the future.
