The Institute of Concentrated Photovoltaic Systems (ISFOC) is a company established within the Castilla-La Mancha Finance Institute Group, attached to the Ministry of Sustainable Development of the Castilla-La Mancha Regional Government. ISFOC focuses its activities on the Research and Development of solar photovoltaic energy, energy efficiency, and distributed sensor systems, as well as the development of innovative green hydrogen generation systems.

The ISFOC headquarters, along with the laboratories and the main concentrated photovoltaic plant in operation since 2008, are located in Puertollano, from where all the Institute's activities are coordinated. Currently, the various technologies in operation include: Isofotón in Spain, Solfocus in the USA, and Concentrix from Germany. Additionally, at the beginning of 2012, the construction and operation of a new 1600 kW photovoltaic plant, featuring technologies from companies such as Concentrix from Germany, emcore from the USA, Arima Eco from Taiwan, and Sol3g and Renovalia from Spain, were completed.

The objective of these pilot plants is to obtain feedback to help and support the industry in technology development, as well as to gather valuable information for the sector, such as reliability, suitability, and the production of each technology. The establishment of ISFOC in Castilla-La Mancha represents a fundamental vehicle for the development of concentrated photovoltaic (CPV) technology, which is our main objective, as well as the generation of key knowledge about this technology.

In 2006, ISFOC was established with its headquarters located in Puertollano, Ciudad Real. At that time, the human team was hired to make the implementation of CPV a reality, starting with the acquisition of various plants of this technology that would be installed in demonstration fields, as well as the means to evaluate their performance.

Today, ISFOC has several demonstration plants belonging to different technologies that provide valuable information to manufacturers across the entire CPV value chain, to investors, and to the scientific community in general. Its facilities consist of fully equipped laboratories for testing the various components of the plants. Additionally, the human team, made up of about 30 professionals, has developed knowledge that, along with the facilities and demonstration plants, makes ISFOC a world reference in the study of CPV, with its results being published worldwide.
