They are used in a number of applications:

    Collectors for domestic water and space heating
    Concentrating solar power (CSP) troughs industrial process for heating and solar air conditioning for low and middle temperatures
    CSP Fresnel as secondary mirrors
    Concentrating photovoltaic applications

Solar initiatives in developing communities

Solar cookers offer high energy value without negative environmental impact.

These cookers are particularly useful in areas or villages with little access to energy sources apart from wood, the use of which leads to deforestation.

In this context, Constellium’s Packaging and Automotive Rolled Products business unit is supporting many initiatives in the development sector:

    CDM (clean development mechanism) project in Indonesia (Banda Aceh Region)
    Joint project with Humanitrek in Nepal and India
    An active part of the solidarity chain for Haiti following the earthquake in 2010

Photovoltaics are used to transform sunlight directly into electricity. Concentrated Solar Power (CSP) technology converts it for indirect use.
