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 number 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 eliminate 585 tons of CO₂.
Maximizing energy density within limited rooftop space was essential, a challenge ideally suited to AIKO’s high-efficiency N-Type modules.
“Efficiency per square metre 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,” commented 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.
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.
