Refurbishment of the historic Food Market of Bejar, Salamanca (Spain), with the installation of a 176 m2 photovoltaic skylight. This skylight combines amorphous silicon modules of varying degrees of transparency and colours which form a mosaic inspired by the neoplasticism of Piet Mondrian. Besides, due to an installed power capacity of 6.7 kWp it can generate almost 9,000 kWh of energy per year, and prevent the release of 6 tons of CO2 .
Part of the power generated is sent to be stored in batteries, and the rest is sent to the grid for the building’s own consumption.
