Abstract
The photovoltaic systems sector is in full renovation continually demanding a new system that allows the user to monitor his project from long distance. One of the systems that is currently being implemented in photovoltaic farms is known as the Internet of Things. Through this system, it is intended that the user can know in the real time the status of his photovoltaic systems panels. This paper presents a new solution based on LoRaWAN technology that allows the user to have the necessary information to achieve high efficient of the photovoltaic systems panels. This system is to design and implement a new measuring circuit for measuring the output voltage and current of the PV panels from long distance by using LoRa Technology. To test the correct functioning of the device, two tests have been carried out. The first one corresponds to an essay in which the maximum distance at which a node can communicate with the gateway is measured. While the second test means measuring the voltage and current output of the photovoltaic panel of the full system. The main advantages of the final circuit can be used to monitor PV panels with low-cost, and to have high-efficiency performance from long distance.

Summary
The electricity generated by photovoltaic installations is economically very competitive due to the great technological advance and the reduction of investment costs, experienced in recent years. The implementation of the low cost of photovoltaic monitoring system network based on LoRaWAN, treatment and visualization of information of photovoltaic systems, is carried out using open source software and hardware, offering a modular system, adaptable and with a great capacity for integrate into new technological trends. The IoT is an applied area that seeks to develop electronic circuits that allow the internet connection to devices, with the aim that they can exchange data with other internet users Large multinationals such as Cisco and Microsoft develop and offer multiple applications such as the following: Priority of saving lives is by using intelligent transport solutions accelerating traffic flows, reducing fuel consumption. LoRaWAN Technology The long-range and low-power (LoRa) wireless platform is the predominant technological option for the construction of IoT networks worldwide This technology uses frequency spectra for public use in the ISM band (such as Wi-Fi and Bluetooth). This circuit is designed to show the components of voltage and current circuits
