The installation of 301 m2 (3,239 sqft) is located in the CIF building, an industrial-type building with an office area that belongs to the multinational Larsen & Toubro (L&T).


It is composed of low transparency amorphous Silicon Photovoltaic Glass and a glass configuration of 6+3+6. In total, there are 110 rectangular-shaped units, which measures 1,849x1,245 mm (47 PV glass units) and 2,456x1,245 mm (63 PV glass units).

Each glass has a double argon chamber, providing excellent thermal and acoustic insulation and notably improving the comfort of people inside the building. This quality is quite important for a city with a tropical climate like Kancheepuram, where it frequently exceeds 40ºC (104ºF) during the summer.
