Designing a maximum power point tracking system for a monocrystalline silcion solar module using the Arduino microcontroller and synchronous Buck converter

Abstract

Maximised power output and efficiency in a photovoltaic (PV) system for specific conditions can be obtained by using a maximum power point tracking technique (MPPT). Many tracking algorithms have been developed for this purpose. This paper presents the design and methodology used to create a photovoltaic charge controller that uses the algorithm developed for maximum power point tracking. The charge controller presented in this work is not only designed to maximise the power from the solar module but also contains added features that make the system beneficial to the researcher. The suggested system has used Perturb and Observe (P&O) MPPT method for the design and implementation. In this technique, the controller delivers the PWM (pulsewidth modulation) signal using the Arduino microcontroller to regulate the voltage. A DC-DC (direct current-direct current) synchronous Buck converter is used to interface the PV module with the load. The results are gained for two systems:-using a microprocessor controlled MPPT operating from a PV module, and a PV module connecting directly to the load. It is found that the MPPT is effective, providing the highest power to the operating load under changing outdoor conditions. The experimental results indicate that for cloudy days, it is suitable to use MPPT control, which that will enhance the PV production power compared to situation in which the PV module is directly connected to a fixed resistance.

Optimization of tilt angle and experimental study of standalone PV system for clean energy home supply in Baghdad

“…The ambient temperature was measured using electronics thermometer beneath the shade for avoiding the straight solar radiation influence. The straight radiation was measured by digital soler meter, and the performance of (PV) panel was collected by solar analyzer to record the P-V and I-V curve at each hour of working day, figure [3]. The frame of (PV) design has to be movable to provide the required tilt angle, as displayed in the figure [4].…”

“…At the same date, the solar radiation was measured experimentally by using a small pyranometer model pyrometer, (TES-1333/1333R) solar power meter, ha-ving a range varied from (0 to ~2000W/m 2 ). It was fixed into the upper comer of the insulation attached to the collector, parallel to the face of the collector, as revealed in the figure [3]. Therefore, the reading of the pyranometer is the actual solar intensity incident on the face of the collector.…”

“…The solar module analyzer of elucidated in the figure [3] was employed to introduce: the current-Volte (I-V) and power-volte (P-V) curves for solar module; compute the ultimate solar power (Pmax), specify the ultimate voltage (Vmax), the ultimate current (Imax), the voltage at open-circuit (Vopen), the current at short-circuit (Ishort); and forecast the electrical effectiveness it can be seen this characteristic of the performance of PV panel shown in figure [10]. The highest intensity of solar radiation was recorded at the hours 11:00, 12:00, and 13:00.…”

“…The photovoltaic module or the thermal collector performance depends upon the solar radiation quantity that attains to it. Solar radiation relies on the period, site and location of the panel with regard to the sun [2,3].…”

IoT based early warning system for torrential floods

“…It has been present in the industry for over a decade years as a tool that enables the transformation of outdated production equipment into Computer Numerical Control (CNC) machines [3]. The popularity of the Arduino was especially contributed by its simple Integrated Development Environment (IDE), which allows rapid creation of short snippets named Sketches in C++ programming language and their transfer to the microcontroller via a plain USB cable [4]. In recent years, there has been a noticeable shift in the market towards the commercial use of such microcontrollers in everyday life, among other things in systems intended for individual consumers as autonomous alarm systems [5], or as a part of a more complex home alarm system, in both cases with the role of flood detection in basements [6,7,8].…”
