Onyx Solar® executed the modernisation of the façade of Femsa’s headquarters in Monterrey, Coca-Cola’s main bottling plant worldwide.

This ventilated façade solution consists of integrating a double skin of photovoltaic glass whose mounting structure is not visible from inside the building.

PTo this end, 370 large-sized grey amorphous silicon glass modules, with a semi-transparency degree of 20% (L vision), were designed to measure.



  • superficieTotal area - 588 M2
  • electricidad generadaElectricity generated per year - 17.223 kWh
  • puntos de luzTotal light points operating 4 hours a day - 981 lighting points
  • emisiones CO2 evitadasAvoided CO2 emissions per year - 11.539 CO2
  • barriles petroleo ahorradosBarrels of oil saved per year - 10 barrels


The photovoltaic glass of the façade generates approximately 17,200 kWh and prevents the release of over 11 tons of CO2 into the atmosphere.


Furthermore, the ventilated façade is doubtless an optimal construction solution from an energy-efficient viewpoint. In fact, it has been estimated that the energy savings derived from the remarkable insulation produced by this construction solution may reach as much as 40% of the energy requirements of the building. If we add to these savings the possibility of generating clean, free energy from the sun by means of the use of photovoltaic glass, we are doubtless looking at one of the most effective construction solutions on the market.

Alfredo de la Rosa"Working on this project with Onyx Solar® has been a rewarding experience. Both companies took on the challenge to execute Mexico’s first photovoltaic glass façade in record time, and the result has been most satisfactory. Like in all projects, working with top-notch specialised companies is a guarantee of success”.

Alfredo de la Rosa, Manager of Internal Civil Works at FEMSA.
