Barracks 1 in the Picarral district in Zaragoza will be the first public building in Spain to have a hybrid solar installation (photovoltaic – thermal panels) for self-consumption, which simultaneously produces electricity and heat (hot water) .
The installation consists of 28 hybrid solar panels, which allow both the production of electricity and heat for domestic hot water. Annual savings of 9,618 kWh of electricity and 31,184 kWh of thermal energy are expected (respectively 960 and 2,500 euros).
In the coming days, the first hybrid solar installation for self-consumption in a public building in Spain will be inaugurated in Zaragoza. The Zaragoza companies Endef and Dolmen Ingeniería have already started work on installing the plates in the number 1 fire station in Zaragoza and calculate that the assembly will be ready to be put into service at the end of February.
The fundamental difference with conventional solar installations, where the production of electricity and hot water is done independently, by installing photovoltaic and thermal solar panels, in these hybrid installations the production of heat and electricity is generated in the same solar panel. A great advantage for installation in buildings with limited space for installation.
The installation was carried out by Endef and Dolmen Engineering. It cost 50,800 euros.
This installation is part of the actions carried out by the city council of Zaragoza, with the objective of reducing its polluting emissions by 20% by 2020. This installation alone will prevent 18.6 tonnes of CO2 emissions per year.
