The base transceiver stations (BTS) are telecom infrastructures that facilitate wireless communication between the subscriber device\nand the telecom operator networks. They are deployed in suitable places having a lot of freely propagating ambient radio frequency\n(RF) and solar energies. This paper is aimed at converting received ambient environmental energy into usable electricity to power\nthe stations. We proposed a hybrid energy harvesting system that can collect energy from RF and solar energies at the same time.\nThe sources are combined to provide to a significant amount, to contribute to operational expenditures that reduce energy costs,\nand to improve the energy efficiency of the base station sites in rural areas from the most common renewable resources since\nthe base stations are major consumers of cellular networks. The hybrid systems are designed with circuits, simulated, and\ncompared to show their good performance to the base stations. PSIM, PROTEUS, and MATLAB software are used to simulate\nfor evaluating the voltage and the current output of the hybrid systems that meet the power requirements. The design and\nsimulation results show the feasibility of our proposed method with the battery storage that can be deployed not only in real\nbase stations but also for other electrical operated systems.
