Solar PV Skylight in Crete

Mediterranean Agronomic Institute chania



A semitransparent photovoltaic (a-Si) skylight was installed in the Mediterranean Agronomical Institute of Chania (MAICh) Campus in Chania, Crete.


The new structure will provide shade to some of the core areas of the campus, with a high potential of visibility among a number of visitors, researchers and students.

The PV installation is made up of 120 pieces of amorphous silicon glass used for the retrofit of the biggest and principal skylight of the building. Over 19,160 kWh per year will be produced, saving CO2 emissions and reducing the energy bill of the campus.


The Mediterranean Agronomic Institute of Chania (MAICh) is an educational and research institute focusing on the Mediterranean agriculture. It is located in Chania (Crete, Greece) and belongs to the four agronomic institutes of the International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM).


The Greek ministry of Rural Development and Food owns the building and the Mediterranean Agronomical Institute of Chania has been fully involved in the installation process and the future capitalization of this pilot application.


The project is part of the European project DIDSOLIT- PB, which main objective is the promotion of decentralized solar technologies for electricity generation in public buildings.
