There is no better way to check the health of your photovoltaic system than to utilize a remote monitoring system. Monitoring and tracking of photovoltaic systems are crucial for reliable functioning and optimal yield of any solar electric system. This paper aims to introduce a remote electronic monitoring system. The said system will allow us to retrieve, process and transfer, in real-time, the photovoltaic station data remotely. The main objective of this work is to build a robust system that could be said as a reliable and low-price system, which will allow the transfer of the installation state to the remote operator in real-time or store it on an online database. Our intelligent wireless system is contained two parts, the first part including a hardware system designed around a microcontroller card (the Raspberry pi3 card) and a second part including the software part, which is the installation and configuration of open source applications on the Raspberry card. On the other hand, the configuration of an online database is presented. The database will offer us the possibility to store and process the station’s data remotely and in real-time. Moreover, we also developed an application that plays the role of an interface for our monitoring Raspberry Pi3 machine.

Introduction Renewable energies (REs) are a set of means of generating energy from unlimited (on a human scale) sources or resources, available without time limits or recoverable more quickly than they are consumed. Renewable energies are often spoken of as opposed to fossil fuel energies, whose stocks are non-renewable and limited: coal, oil, natural gas. The renewable energies are unlimited which produced from many sources such as the wind and the ray of sun [1]. REs are often referred to as "clean energies" or "green energies". The environmental effect of their operations is very low which makes them a major element in companies' Corporate Social Responsibility (CSR) strategies in terms of sustainable development. The exploitation of renewable energies theoretically generates few pollutants: in particular, electricity of renewable origin emits very little CO2 especially when compared to fossil fuels such as coal. For this reason, renewable energies are a particular vector of the fight against global warming. They are also considered as a factor of resilience because they allow decarbonized and decentralized productions. There are different energy sources that produce several types of renewable energy. Maybe the most known is still the solar energy. This type of energy comes directly from the capture of radiation coming from the sun. Specific sensors are used to absorb the energy of the solar radiation and rebroadcast it according to two main modes of operation: • Solar photovoltaic (solar photovoltaic panels): solar energy is captured for the production of electricity. • Thermal solar (solar water heater, heating, solar thermal panels): solar heat is captured and is redistributed, and more rarely used to produce electricity. The global market stagnated last year, with around 98 GW deployed. For 2019, the experts expect stronger solar growth, PV Market Alliance warned its forecast for 2019 that global solar installations would grow by about 20% to as much as 120 GW, and volume of 180-200 GW by 2022 [1]. In the recen years, Morocco has encaged in a startegy of alternatives energies, all determneted to move from a country importing all its oil and gas needs to major producer renewable energy (figure2), whereas it depended totally, and until a near past, of the outside for the energies needs. Through its renewable energy development strategy, Morocco aims to ensure its relativity energy independence, contribute to ASTESJ ISSN: 2415-6698 * Youssef Bikrat,Email: y.bikrat@ump.ac.ma Advances in Science, Technology and Engineering Systems Journal Vol. 4, No. 6, 94-98 (2019) www.astesj.com ISAECT 2018 Extended Papers https://dx.doi.org/10.25046/aj040611
