This academic year, one of the ESES thesis project has been carried out at the largest solar research center in Europe: The Plataforma Solar de Almeria (PSA). The PSA in Almeria, Spain (www.psa.es) is one of the most internationally recognized research centers for solar concentrating technologies. The ESES student Maria Elena Cantos-Soto studied as her thesis project at PSA the “Optimization of cleaning methods for parabolic-trough concentrating solar power plants”. CSP field performance depends strongly on the parabolic-trough concentrating mirrors reflectance. For that reason, PTC mirrors need to have an optimal level of cleanness to enable the reflection of the solar beam into the focal line, and therefore, washing CSP mirrors represents one of the most costly O&M tasks. Hence, not just keeping a suitable reflectance level but also make it cost-effective is a crucial issue for CSP fields.
