Los Llanos Irrigation Community Solar Pumping System of 470 kWp
Located in Pina de Ebro, the Los Llanos Irrigation Community irrigates 863 hectares of herbaceous crops using surface irrigation. Water is drawn from the Ebro River by three hydraulic pumps with an estimated installed capacity of 424 kW, elevating water to the start of the community’s canal network, from where it is distributed by gravity through irrigation ditches.
The irrigation pumps are powered by the electrical grid. Due to the irrigation system and scheduling, the equipment requires continuous operation for extended periods, almost year-round.
Given these conditions, the community members considered an alternative energy system to reduce dependency on the grid. They contacted Bombeatec, whose specialized technician conducted a preliminary audit. Using simulation software, the optimal solution for this case was determined. A tailored system was designed, and a technical study proposed installing a 470 kWp self-consumption photovoltaic system with solar trackers. Once approved, the installation included land preparation, pile driving, mechanical assembly of the structure, inverter installation, and the setup of an autonomous control system designed by Bombeatec.
This control system monitors the entire installation, allowing pump activation based on solar availability. It optimizes pump startups and shutdowns according to solar intermittency and cloud cover and manages operations to align with tariff periods and contracted power.
Additionally, this technology enables remote monitoring of the system. Customers can control it via their smartphones, while Bombeatec can intervene remotely if issues arise. Since its implementation, Los Llanos Irrigation Community has significantly reduced its electricity costs. The photovoltaic plant can pump an annual water volume of 7.939 hm³ and provide energy for 2,472 hours of pumping annually.
To fund the installation, the Los Llanos Irrigation Community applied for a 2021 grant under the Rural Development Program for Aragón 2014-2020, proposed by the Aragón government to modernize and improve irrigation systems.
Bombeatec contributes to the transition toward a new energy model based on efficiency and renewable energy use while minimizing environmental impact. Solar photovoltaic pumping provides an efficient energy supply at competitive prices, enhancing energy diversification, supporting environmental conservation, encouraging savings measures, and promoting renewable and local energy resource use.
Based in Zaragoza, Bombeatec specializes in solar photovoltaic pumping and aims to deliver the most optimal technical solution tailored to client needs and existing setups. Bombeatec offers reliable solutions that help farmers save costs and develop high-value, high-power solar pumping systems.
