Iberdrola Ingenieria & Construcción Mexico SA de C.V. is a division of the Spanish Iberdrola Group, one of the largest energy supply corporations in the world. The commercial activities of the company include the provision of technical services, ranging from feasibility studies all the way through to “turnkey” projects, both for other companies in the Iberdrola Group and for third parties.

Iberdrola decided to use 130 Watt class CIS modules from Solar Frontier to generate 1.5 MW in a 5 MW project in Cerro Prieto, Mexico. About 11,600 of these modules had already been shipped in August and September 2012. The Cerro Prieto project was conceptualized, financed, supervised and is operated by the state energy supplier in Mexiko, Comisión Federal de Electricidad (CFE), this is the largest PV system currently operating in Mexico. In this project, Iberdrola is using both Solar Frontier PowerModules and modules based on a competing technology.

The hot climate of Mexico, where the average annual temperature is 22.9 °C, and the fact that the Solar Frontier PowerModules are mounted on singleaxle solar tracking systems, enhances the effect of the good temperature coefficient. The outstanding temperature stability of the CIS modules results in high, more stable yields in these hot climatic conditions. Even the presence of sulphydric acid (H₂S) in the atmosphere does not impair the perfomance capabilities or the durability of Solar Frontier PowerModules.
