IV. PERFORMANCE ANALYSIS A number of performance indicators are suggested in the literature in order to evaluate the technical-economic feasibility of solar cooling systems. In the present work, we introduce as energy indicator: The solar fraction SF: This rate indicates the portion of solar energy contribution as a response to the cooling need. It can be expressed using (1)

Where: Qe is the cooling load (kWh) and Qaux is the energy consumption of the auxiliary system (kWh)
The economic study provides an analytical rigor to prove the feasibility of the solar cooling project. It focuses on current and projected costs for the equipment associated with the proposed solar thermal cooling installation. The economic analysis is based in the following indicators: TABLE
