Automated Intelligent Monitoring and the Controlling Software System for Solar Panels

The inspection of the solar panels on a periodic basis is important to improve longevity and ensure performance of the solar system. To get the most solar potential of the photovoltaic (PV) system is possible through an intelligent monitoring & controlling system. The monitoring & controlling system has rapidly increased its popularity because of its user-friendly graphical interface for data acquisition, monitoring, controlling and measurements. In order to monitor the performance of the system especially for renewable energy source application such as solar photovoltaic (PV), data-acquisition systems had been used to collect all the data regarding the installed system. In this paper the development of a smart automated monitoring & controlling system for the solar panel is described, the core idea is based on IoT (the Internet of Things). The measurements of data are made using sensors, block management data acquisition modules, and a software system. Then, all the real-time data collection of the electrical output parameters of the PV plant such as voltage, current and generated electricity is displayed and stored in the block management. The proposed system is smart enough to make suggestions if the panel is not working properly, to display errors, to remind about maintenance of the system through email or SMS, and to rotate panels according to a sun position using the Ephemeral table that stored in the system. The advantages of the system are the performance of the solar panel system which can be monitored and analyzed

Determination of strain in moving objects by X-ray diffraction using synchrotron radiation

A novel method for the determination of strain in moving objects is presented. It is based on X-ray diffraction in parallel-beam geometry. This geometry is not affected by errors of the sample position. Thus also moving objects can be investigated. Feasibility tests were made investigating the rotor blades of a turbo pump during rotation

Preparation, Characterization And Electrochemical Studies Of 1,1′-bis(diphenylphosphino)ferrocene (dppf) Derivatives. Crystal Structure Of [dppfco(no)2] [sbf6]

The neutral dppfFe(NO)2 (1), the novel cationic [dppfCo(NO)2] [SbF6] (2), as well as the dppfFe(CO)3 (3) (dppf=1,1′-bis-(diphenylphosphino)ferrocene) complexes were prepared and characterized. The interaction between the two metallic centers through the dppf ligand was studied in the solid state by 57Fe Mössbauer spectroscopy and in solution by cyclic voltammetry. The Mössbauer parameters are compared with those of other dppfMLn complexes. Electrochemical studies performed on these complexes show the great influence of the MLn moiety on the redox processes of the dppf iron center. The crystal structure of complex 2 was determined (C34H28CoF6FeN2O2P 2Sb). The compound crystallizes in the triclinic, space group P1̄, a = 10.441(2), b= 10.755(2), c= 17.320(5) Å, α = 104.10(2), β = 0.504(10), γ = 111.504(10)°, U= 1744.7(7) Å3, Z = 2, R = 0.0765, wR2 = 0.1878. In this complex, the cobalt atom is coordinated to two nitrosyl ligands and to phosphorus atoms of the dppf ligand, providing a distorted tetrahedral geometry. © 1997 Elsevier Science S.A.26611927Andy Hor, T.S., Phang, L.-T., (1990) J.
