Concentrated Solar Power (CSP) is one of the oldest and most convenient technologies for converting solar power into electricity.

Airlight Energy's concentrated photovoltaic (CPV) is similar to CSP in design, as it uses the same structure (collector and pneumatic mirrors), but it differs from CSP in terms of the receiver, where solar radiation is converted directly into electric current using highefficiency photovoltaic cel

At present, the only technologies capable of storing electricity that can then be supplied at a later time at more competitive prices are: CAES and PHS
