This Report examines the performance and the economy for residential and commercial solar water heating SWH technology, specifically flat plate collectors. Two case studies were considered: My house in Madinah Al-Munawarah region (residential) and 25MW solar water heater project in prices Norah bent Abdurrahman university PNU (commercial) in Riyadh. System Advisory Model SAM was used to perform the analysis, the model input parameter is obtained from the original design of the systems and from the collectors’ data sheets and some not available values are assumed reasonably or kept ad the default value of the software. The technical performance and the economics of the selected SWH system for each sites have been estimated using the SAM program by determining the delivered heat, solar fraction, the savings in energy and money, payback time, and net present value. As a result, the simulation of the two cases showed that using the SWH system in Saudi Arabia is viable, and deploying the SWH technology may cause up to 45% reduction in electricity consumption in case of The payback period for the Madinah SWH system is 7.6 years which considered to be good and promoting to be deployed. Madinah witnesses better solar radiation but also has a hotter average temperature than Riyadh, the solar fraction for residential was 0.58 which is higher than commercial of only 0.02. But the capacity factor for the commercial in Riyadh was higher of which 17%. While Madinah SWH system capacity factor is 9.5%.
