Installation of a photovoltaic curtain wall at the new headquarters of the Guadalhorce Valley Rural Development Group, reducing the energy consumption of the building. This enclave, located in the province of Malaga, was born to be a Social, Economic and Environmental Innovation Centre to house the bodies and associations currently working in the region on the development, promotion and innovation of the valley.

This time, Onyx Solar®’s photovoltaic glass was installed on the façade of the building, forming a remarkable curtain wall capable of generating over 2,700 kWh per year, with a peak installed power capacity of 2.5 kWp.

The glass modules, made from amorphous silicon, are largesized and were made to measure to satisfy the requirements of the client, the Andalusian regional government. It is of note that the photovoltaic glass employed is of the low-emissivity (low-e) type, which improves the thermal and acoustic insulation of the building and enhances energy savings in the same. It further features a semi-transparency degree of 20% (L vision), which enables the uniform passage of light into the interior, reducing the need for artificial light while preventing the ingress of heat and the undesired greenhouse effect due to its Solar (g) Factor of between 5% and 40%, depending on the degree of semitransparency. All the above is conducive to an improvement in the comfort of those inside, in addition to being in keeping with the natural surroundings of the location of these headquarters by preserving the aesthetics of the building.
