Onyx Solar has provided photovoltaic glass to create a photovoltaic skylight, in the Port Authority of the city of Malaga, in the Spanish region of Andalusia.
The installation has a total of 200 square metre and has a peak power of 20 kWp. It is composed of 70 crystalline silicon photovoltaic glass modules in different sizes and shapes.
Data
- Total Area – 200 square metres
- Electricity generated in 35 years – 923.487 kWh
- Total lighting points operating 4 hours per day in 35 years – 1814 lighting points
- CO2 emissions avoided in 35 years – 619 tonnes of CO2
- Barrels of oil saved in 35 years – 543 barrels per square metre
This refurbishment consisted of replacing the existing and inactive glass with Onyx Solar’s photovoltaic glass with a 6T+6T configuration. With this project, the Port Authority of Malaga will be able to start generating its own clean energy, and considerably improve the internal comfort of the building by filtering harmful radiation from the sun (IR & UV), improving thermal transmittance (U Value) and solar factor (g-value).
Customization is one of the key elements that define Onyx Solar. The company’s glass modules are 100 percent customizable for the needs of the customer. For the full refurbishment of this skylight, it was necessary to adapt the size of the photovoltaic glass modules to the existing structure of the building.
Onyx Solar supplied glass in rectangular, triangular, and rectangular trapezoidal shapes.
Rectangular glasses have 9 different sizes, ranging from 2,580 by 920 millimetre to 2,700 by 1,320 millimetre. The triangular glasses measure 1,251 by 1,256 millimetre (base-height). And finally, the rectangular trapezoidal-shaped glass reached 3,459 millimetre (lower base) by 2,554 millimetre (upper base).
The chosen transparency is medium, with enough space between the polycrystalline solar cells to allow the entry of natural light into the building.
The city of Malaga belongs to Global Covenant of Mayors for Climate & Energy, the largest global alliance for city climate leadership built upon the commitment of over 10,000 cities and local governments. These cities hail from 6 continents and 140 countries. In total, they represent more than 900 million people. Increasingly, cities and local governments across the globe are heeding the call to action.
