Pueblo Verde de Almonte is redefining how rural communities access clean power in Spain. Located in Almonte (Huelva), this groundbreaking shared self-consumption project delivers renewable electricity directly to more than 3,500 local users – making it the largest solar community in Spain by numbers of users – without requiring any upfront investment. At the core of the 1.45 MW system are over 2,000 high-efficiency AIKO ABC modules, supplied by Sumsol and installed by Inercia Energía (part of GRUPO CECSA) across 7,500 m² of rooftop space spanning 20 industrial buildings.
Commissioned in three phases throughout 2025, the €1.1 million project is Spain’s largest shared self-consumption scheme by number of supply points. Instead of exporting power to the wholesale market, electricity is injected directly into the local grid, covering up to 30% of each connected household or business’s annual usage. Alongside lower bills, the system is expected to generate approximately 2.25 GWh/year and abate 585 tons of CO₂, equivalent to planting 29,000+ trees.
Designed for Maximum Yield
Maximizing energy density within limited rooftop space was essential – a challenge ideally suited to AIKO’s high-efficiency N-Type modules.
“Efficiency per square meter was essential. AIKO’s modules allowed us to increase capacity while covering the same area – a decisive factor given the nature of the building stock,”
said Antonio Abad, Head of Business Development at GRUPO CECSA.
Thanks to their superior W/m² performance, the final layout achieved +61.75 kWp of installed capacity within the same area, saving approximately 264 m² of roof space versus a conventional TOPCon configuration. This translates to +212 MWh additional generation in the first year, equivalent to +6,477 MWh over 30 years. Based on current retail tariffs, the installation’s LCOE is estimated at €0.01341/kWh, significantly lower than the regional electricity price of approximately €0.15/kWh.
Engineered for Southern Spain’s Climate
Operating in one of Spain’s hottest regions requires solar modules that can maintain long-term efficiency and reliability under high temperatures. This is where AIKO’s ABC modules stood out. With a better temperature coefficient of -0.26%/°C compared to -0.29%/°C for TOPCon modules, they are able to reduce energy loss in hot conditions. Additionally, their lower degradation rate – just 1% in the first year and 0.35% annually thereafter – helps ensure consistent performance throughout the system’s lifetime. These characteristics help maintain long-term output and further enhance the value of local energy generation.
A Replicable Path Toward a Carbon-Free Society
Pueblo Verde de Almonte offers more than local impact. Its structure – modular, privately funded, and technologically robust – makes it easily replicable in other municipalities across Spain and Europe. By combining public benefit with technical and financial viability, it provides a compelling framework for collective self-consumption at scale.
As Spain accelerates its energy transformation, AIKO – together with its partners – remains committed to building a smarter, cleaner, zero-carbon future.
