The hybrid solar photovoltaic systems are among the most widely used photovoltaic systems due to their high electrical efficiency. In this paper, a set of smart hybrid photovoltaic systems, integrating a semi-transparent photovoltaic panel with smart hybrid solar collector tubes is proposed. Additionally, a smart cooling system is used for the first time to perfectly stabilize the electrical efficiency of the proposed hybrid systems for different solar irradiation. These new systems are mainly proposed for the first time to improve the electrical efficiency of a semi-transparent photovoltaic panel. To obtain the effects of sun irradiation and linear Fresnel lens on the performance of each hybrid system, a set of mathematical equations is coded in MATLAB software. The main results revealed that the maximum electrical efficiency of the SPV/SHC/Bi2Te3, SPV/SHC/PbTe, SPV/SHC/Bi2Te3/Bi2Te3, SPV/SHC/Bi2Te3/PbTe, and SPV/SHC/PbTe/PbTe in absence of smart cooling system are respectively 2.88%, 3%, 5.76%, 5.88%, and 6% higher than that of the stand-alone SPV system. When these hybrid panels are equipped with smart cooling system, the maximum electrical efficiency of the SPV/SHC/Bi2Te3, SPV/SHC/PbTe, SPV/SHC/Bi2Te3/Bi2Te3, SPV/SHC/Bi2Te3/PbTe and SPV/SHC/PbTe/PbTe are respectively 3.58%, 3.7%, 6.46%, 6.58% and 6.7% higher than that of the conventional SPV system. These results also showed that the SPV/SHC/PbTe/PbTe system with smart cooling system is electrically more efficient than the other systems, which is due to its higher efficiency and power output of 14.1% and 410.271 W. The electrical efficiency of the proposed hybrid systems, equipped with an intelligent cooling system, stays stable for higher and medium values of sun irradiation. These results provide a definitive solution to the problem of decreasing electrical efficiency of photovoltaic panels due to the increase of its temperature.
