Refurbishment of the historic Food Market of Bejar, Salamanca (Spain), with the installation of a 176 m2 photovoltaic skylight.
FEASIBILITY STUDY OF AMORPHOUS SILICON PHOTOVOLTAIC SKYLIGHT IN SALAMANCA
Reduction in HVAC energy demands
Internal Rate of Return
- Total area - 176 M2
- Electricity generated in 35 years - 255,960 kWh
- Total light points operating 4 hours a day in 35 years - 502 lighting points
- CO2 emissions avoided in 35 years - 171 Tons of CO2
- Barrels of oil saved in 35 years - 151 barrels per m2
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.
