English: This true colour image, acquired by Sentinel-2B on 1 May 2020, shows the Nuñez de Balboa photovoltaic plant located in Spain, the largest in Europe. The plant is in the Extremadura region, and extends over an area of approximately 1,000 hectares (10 square kilometres) and includes the municipalities of Usagre, Hinojosa del Valle and Bienvenida, in the province of Badajoz. The plant, which has a capacity of 500 megawatts, was built within the space of just one year and was completed in 2020. It will produce clean energy to supply the needs of 250,000 people a year, offsetting the emission of 215,000 metric tons of CO2 into the atmosphere annually. The Copernicus Sentinel-2 mission is composed of two twin satellites, Sentinel-2A and Sentinel-2B. These satellites are able to detect solar farms and track their expansion over time. This is possible because the mission has an average revisit time of 5 days with global coverage and provides multispectral data on 13 different spectral bands, with a maximum spatial resolution of 10 m. Copernicus Atmosphere Monitoring Service data is also used by solar energy developers to predict the future output of plants, or evaluate the impact of dust deposits which impact the efficiency of solar panels.
