The aims of the programme is to reach 9,000 m2 of solar surface, in order to supply 60 % of the annual demand of domestic hot water. Hospitals have high levels of hot water consumption and most of them have accessible surfaces for the installation of solar collectors. These buildings are also a good showcase for the solar technology.
The total surface with solar installations has been multiplied by 3.4 times from the beginning of the plan. The objective of the Hopisol Programme is to carry out Solar Thermal installations in 23 hospitals of the Castilla y León region.
