In the fierce transformation of the European energy landscape, Spain is like a shining green star, leading the development trend of solar energy and energy storage with remarkable momentum. There, solar energy resources are envied by the world, with an annual sunshine duration of 2500-3000 hours. The radiation intensity in the southern Andalusia region is as high as 2200 kWh/m ²/year, nearly twice that of Germany.
At present, Spain has demonstrated its support for the photovoltaic industry through a series of policy adjustments, promoting the development of photovoltaics through the National Energy and Climate Plan (PNIEC), with the goal of achieving a photovoltaic installed capacity of 39GW by 2030. Spain is committed to achieving carbon neutrality and plans to achieve 100% renewable energy generation by 2050, with photovoltaic power generation system being a core component.
In this article, the top 6 photovoltaic module companies in Spain in 2025 will be introduced, from basic information to latest news about these companies. If you are not familiar with how solar photovoltaic works, click and know more about it.
Top 6 photovoltaic module companies in Spain in 2025
At the long-term planning level, Spain has set an ambitious goal of using renewable energy to account for 74% of total electricity generation by 2030. The National Energy and Climate Integrated Plan (PNIEC) has also clarified the development path of the photovoltaic industry, and it is expected that the cumulative installed capacity of photovoltaics in Spain will rapidly climb to 56GW by 2025.
Against the backdrop of the EU's energy transition, the enormous growth potential of the photovoltaic industry has attracted global market attention. Spain's well-established renewable energy electricity price subsidy mechanism and "one-stop" service platform policy have laid the foundation for the explosive growth of the photovoltaic market and are expected to become an important force leading the development of the European photovoltaic industry.
The following is the list of the top 6 photovoltaic module companies in Spain in 2025 for you to know better about the solar market in Spain.
