Countries located on the equator have a relatively high intensity of solar radiation. The thing that is most needed in a solar power plant is the intensity of solar radiation. Based on this, Indonesia is very suitable for implementing solar power plants. The power produced by a solar power plant is directly pro-portional to the intensity of solar radiation received by the solar panels. To maximize electrical power production, it is necessary to design a series of solar panel units to be connected in series or parallel. Solar panels connected in parallel will increase the nominal total voltage, whereas when connected in series they will increase the nominal total current. This research discusses the effect of the series-parallel configuration of solar panel installation on the power production received in a building in the campus environment. The method used to obtain the most optimal energy production is to use a combination of series and parallel solar panels. Daily sunlight data is simulated via PvSyst. The research results show that the most optimal energy production is obtained by designing a series circuit of 20 panels combined with a parallel circuit of 5 panels. The more modules connected in series, the total voltage will increase. The more modules that are connected in parallel, the total current will increase.

“…[ 59 ] In the far field, the electromagnetic wave pattern is nearly uniform, and radiative far‐field wireless power transfer can supply electric power over tens of meters [ 23 ] using high‐frequency radio waves on hundreds to thousands of MHz. [ 60 ] Power transfer is less efficient in the far field than near field. [ 61,62 ] However, far‐field rectennas can also be effectively used for energy harvesting due to omnipresent radiation from distant sources in urban areas.…”

The Internet of Things is currently one of the fastest-growing branches in electronics. The development of energy storage systems and the miniaturization of dedicated printed circuit boards significantly influence that growth. However, the need for batteries and traditional printed circuit boards still limits devices' minimum size, weight, and cost, narrowing the application area. Energy harvesters and wireless power transfer systems fabricated with printed electronics can significantly reduce such devices' weight, size, and cost. Printed electronics technology provides scalable tools for many electronics applications, shortening the validation time and enabling new low-cost or disposable solutions on lightweight and flexible substrates embedded inside 3D printed structures and directly on device housings. Energy harvesting and wireless power transfer systems in electronic devices can provide enough power to minimize battery capacity and size or even eliminate the need for batteries in low-power applications. This review presents an adaptation of printed electronics technology in the fabrication of radio frequency energy harvesters and wireless power transfer rectennas for IoT applications. Last, perspectives for development towards greater integration with microsystems, transient electronics with ecofriendly materials, adaptation for next-generation telecommunication systems, and 3D structural electronics solutions are briefly discussed.

“…The best efficiency occurred when the rotation angle of the directional antenna was 60° at 0.36% [12]. The following research used the same method to cover 10 cm in distances, with an efficiency of 0.00116% and a size of 1.44 cm 3 [14]. The efficiency is low, and the size is still unable to be planted in the human body.…”

This paper aims to design a receiving antenna for harvesting energy using the wireless energy transfer method based on the ultra-high frequency (UHF) band. The study was conducted by comparing four types of the receiving antenna design. A mathematical and experimental analysis has been done to evaluate the performance of the designed antennas. A Yagi-Uda antenna is utilized as the transmitter. The results show that the zig-zag type antenna has the best performance. It can receive electromagnetic energy from a transmitter with maximum efficiency is 0.1% for the receiving antenna volume of 0.34 cm<sup>3</sup>. The proposed method can meet the energy necessity of an implant device with a charging time of approximately 21.61 hours for the 700 mAh rechargeable battery capacity. As our preliminary conclusion, based on our results, this proposed method can be used as a reference for the practice in the WET field and the medical and restricted areas in the electromagnetic energy harvesting case.
