A conceptual design of the power system for a water–lithium bromide absorption system is presented in this work for a given cooling load. The proposed system utilizes both solar thermal and the photovoltaic (PV) generated electrical energy for its operation. The performance of the power system is analyzed over a complete year for a designed operation strategy. It is found that the proposed system can provide an annual-average surplus of 17.4 kWh of energy per day after meeting the in-house energy requirements. Finally, an economic analysis is performed to calculate the payback period of the system.
