An algorithm has been developed to address conventional vs. renewable dilemma. The debate of using renewable energy to replace conventional sources in various cooling systems to partially compensate this energy staggering operation and improve cooling efficiency is still everlasting. Because of numerous uncertainties associated with climatic data and the effect of climate change, the accuracy of predicting the trend of solar cooling's performance is not sufficient; and therefore, the confidence over capital vs. operational expenditure and payback time calculation was diluted. In this project, annual statistical weather data of any location can be analyzed to predict the possible offset that renewable solar can offer to slash energy requirement of a particular cooling or dehumidification system. Matching that analysis against total cost of installation and operation will provide solid ground for investment decision making criteria. The project takes into account location specific boundary conditions such as the cooling demand time series, solar resource availability, climatic conditions, component cost and performance parameters. This methodology evaluates the techno-economic performance of the solar collector systems include solar thermal and solar electric cooling options and account for water generation from ambient moisture as another significant product to be offset from total cost. Testing this algorithm for hot spot locations such as Abu Dhabi revealed an interesting potential for solar cooling investment, although more validation of these parameters are needed.
