Data Acquisition System Solar Panels

The measured variables are the current and voltage generated by the panel so that the power and voltage curve can be plotted to analyze.

Data acquisition system solar panels.

The solar power in the form of irradiance trapped by the earth is 1 8 10 11 mw which is far enough to solve all the present energy crisis in the world if it is used efficiently. For those in the energy industry scada system technology helps to operate solar sites. This project introduces a data acquisition system for solar panel technologies mainly for analysis and report purposes. An acronym for supervisory control and data acquisition scada is a system that links together numerous hardware and software components of a site in order to easily monitor control and analyze performance.

The acquisition is made through a low cost current and voltage sensors and data are presented in excel by using the plx daq data acquisition macro. The two wire coming out from the panel is connected to the input pins a0 a1 of the arduino. The total acquisition costs of a solar panel system do not only include the cost of solar pv panels solar power inverters cables and the pv mounting system but also the planning and installation costs as well as those for starting up and the bi directional meter too. The structure of the equipment used is shown in the figure below.

The pv output is directly connected to test load 30 ω wire wound resistor to measure the data of the system. This real time data acquisition is simulated in labview software. Solar energy is inexhaustible and one of the cleanest renewable sources of energy. This arduino is used only to acquire data from the panel.

Campbell scientific offers automated data acquisition systems specifically designed for solar monitoring applications. Technology exists to improve our lives. The system is made up of two parts the hardware that will be designed using an arduino. The system design is based on a low cost arduino acquisition board.

1 the power generation from solar photovoltaic pv has gradually increased all over the world in recent years. A 4 channel relay card is. The data collected on the 2 nd day is based on the fixed racking system the tilt is fixed the solar pv panel is facing to the south and the panel s elevation is the latitude of bangkok i e 14 as can be seen in fig. Scientific data acquisition board cr3000 and graphical programming software pc 400 has been designed and implemented.

Prior to designing the data acquisition system a small sized pv power generation system consisting of a 6 4kw solar panel a charge controller and a dc to ac inverter has been assembled. The data acquisition system a small sized pv power generation system consisting of a 20w bp solar panel batteries a charge controller and a dc to ac inverter has been assembled.
