The Catalonia Self-consumption Observatory, prepared by the Catalan Institute of Energy (Icaen), reported that in 2025 there were 14,873 new solar installations, representing a 12% growth in the park and an 18.3% increase in installed capacity, with 253.23 MW additional.
In total, Catalonia has 138,419 photovoltaic self-consumption installations, totaling 1,634.55 MW of power.
Recent Evolution
Although the rate of new installations has fallen for the third consecutive year (42,000 in 2023, 21,500 in 2024, and 14,873 in 2025), the trend towards larger equipment is consolidating:
- Installations from 5 to 25 kW: 6,967 new.
- Installations under 5 kW: 6,519 new.
The shared self-consumption, which supplies more than one consumer, grew by 32.8% in the number of installations and 64.2% in power, reaching 2,342 units and 67.8 MW.
Distribution by Sectors
- Domestic: 85.8% of the installations, with 36.8% of the total power.
- Industrial: 3% of the equipment, but 34% of the installed power.
- Large installations (>100 kW): barely 1% of the total, but represent 34.5% of the power.
Territorial Distribution
- Barcelona: 81,193 installations and 964.52 MW.
- Girona: 23,531 installations and 251.13 MW.
- Tarragona: 22,262 installations and 257.1 MW.
- Lleida: 11,433 installations and 161.79 MW.
Promotion Policies
The Minister of Territory, Housing, and Ecological Transition, Sílvia Paneque, highlighted that self-consumption reflects Catalonia’s commitment to the energy transition and decarbonization.
The Government has approved measures for administrative simplification and promotes energy communities through the Comunitatenergetica.cat platform. Additionally, it encourages the installation of solar systems in public buildings through the public company La Energética.
Perspective to 2050
The Energy Outlook of Catalonia estimates that 500,000 self-consumption installations will be needed in service to achieve the decarbonization goal by 2050. This objective implies more than tripling the current park and consolidating a decentralized, sustainable, and participatory energy model.
The photovoltaic self-consumption in Catalonia is moving towards larger and shared installations, consolidating a decentralized energy model. Although the number of new registrations has fallen in recent years, the installed power continues to grow, reflecting a qualitative change in the Catalan energy transition. The challenge towards 2050 will be to maintain the pace of expansion and ensure that households, businesses, and public institutions actively participate in the generation of clean energy.
