CAJASIETE BANK

 

Onyx Solar has provided Photovoltaic Glass to create a Photovoltaic Ventilated Façade for the headquarters of Cajasiete Bank, located in Santa Cruz de Tenerife, Canary Islands, Spain.

 

The project consisted of replacing the existing glass on the Southwest façade with our Crystalline silicon photovoltaic glass.

 

 

 

 

 

Data:

• Total Area - 202 M²
• Electricity generated in 35 years  - 494,402 kWh
• Total lighting points operating 4 hours per day in 35 years - 971 lighting points
•  CO₂ emmisions avoided in 35 years - 122 Tons of CO₂
• Barrels of oil saved in 35 years - 291 barrels per m²

 

Example of a feasibility study of crystalline silicon photovoltaic façade in Santa Cruz de Tenerife:

 

•  Payback time  < 3.7 years

•  Internal rate of return (IRR)  28.3%

The total surface covered is 202 m² (2,174 sqft). Our PV glass is composed of an 8T+8T double laminated glass with 6 ”mono cells with a medium density so that the light transmission is high (transparency degree: 55 %). In addition, they will carry out holes in the 4 corners to adjust to the existing fixing system of spider-type ball joints. There are 54 rectangular-shaped units, which measures 1,959x1,909 mm, in a type of active pattern with variations due to the different existing perforations. The peak power is 18 kWp.

  

 

 

 

Cajasiete(former Caja Rural de Canarias) is determined to position itself as a financial benchmark for sustainability in the Canary Islands. The company leads by example with the transformation of its headquarters into a more sustainable building, thereby helping to boost economic activity in times of crisis through environmental projects.

 

This innovative project executes the photovoltaic installation for self-consumption of the building, and it is the first crystalline silicon ventilated facade to be made in the Canary Islands. More details at Cajasiete's blog.

 

 

 

 

The project has been executed by the Canarian engineering specialized in renewable energy and energy efficiency projects, INRA Servicios Energéticos, and Inovasun, the main contract with experience in executing this type of renewable projects, also from the Canary Islands.
