Selray, a Chilean company formed by German PV developer Saferay and Chilean engineering firm Seltec, has submitted plans to the Chilean environmental authority Servicio de Evaluación Ambiental (SEA) to expand its already approved 9MW PV project to 30MW.
The 9MW PV facility — which is located near the town of La Huayca in the Tarapacá region in northern Chile — is already under construction with phase one complete and operational. As part of phase one, the company installed 1.5MW of PV capacity which was connected to the Northern Interconnected System (SING) grid on 3 October 2012.
The expansion of the facility will require an additional investment of US$46 million as well as eight hectares of private land which will be supplied by the company.
The site near La Huayca was selected due to the favourable solar conditions. Selray reveals that the maximum monthly solar irradiance levels can reach 927 watts per square metre. Furthermore, it is situated away from key areas such as tourist attractions, national parks and human settlements.
If approval is granted, installation of the additional capacity is expected to begin in May 2013.
