Installing a storage system will increase installation costs, however the resulting higher capacity factor can compensate for the higher installed cost which can make installing the storage system economically feasible in case of having sufficient solar resources. In the flowchart shown in Fig. 5, QcollQcoll is the thermal energy collected by the collector, QstorQstor is the energy stored in the storage system, Qstormax is the maximum capacity of the storage system for thermal energy storage, QHEQHE is the thermal energy available for the heat engine, QHEmax is the maximum thermal energy capacity of the heat engine, E is the electrical energy output and EPTCmax is the maximum capacity of the electrical energy output of the system.
