Search Articles Search.The amount of electrical energy requirement is increasing rapidly with the population growth and technology development.

There are ways for generating electrical energy using renewable and non-renewable energy sources. Multiple advantages of solar energy are the key factors behind the usage of solar energy for various purposes.

It can be used for generating electrical power with the help of solar panels and for storing the electrical energy by charging the batteries or feeding into loads.

The sun tracking solar panel is used to track the sun by mounting the solar panel on scratch off lottery ticket codes motor board such that maximum solar energy can be used during the day time. The blow figure shows the block diagram of sun tracking solar panel that consists of a dummy solar panel, a power supply circuit, a microcontroller for controlling ULNA driver and stepper motor for rotating the solar panel.

The block diagram of the solar charge controller consists of different blocks: the solar panel that produces electrical power using solar energy; a charging to switch on and off the charging; a load switch to connect or disconnect load; an indicator for indication purposes; battery for storing energy; and a comparator for comparing and generating control signals. The solar panel charge controller is controlled by a charging mechanism to protect the batteries from under charge, over load and deep discharge conditions.

A set of green and red LEDs are used for indicating fully charged condition and under or over or deep discharge condition, respectively. Here even though a non-MPPT solar charge controller can facilitate the protection of batteries from undesired charging conditions, but it is unable to increase the efficiency of the system.

Generally PV panels are built for 12V and are used to put output in the range of 16 to 18V. But the actual value of the 12V batteries is in the range of Consider a watt rated solar panel at a particular voltage and current, suppose the current rating is 7.

If we connect this watt solar panel to a battery using a non-MPPT solar charge controller, then we can get a power which is equal to the product of current of the solar panel: 7. Thus, we get a loss of 41 watts MPPT technology is usually a digital electronic tracking that tracks and compares the battery voltage with the solar panel voltage such that best power at which the battery can be charged using solar panel can be figured out.

Notice that while charging the battery the amperes are considered. The solar panel voltage Thus, the battery gets 12V at For charging the battery a high voltage helps to force the current in. In fact, practically, the output of the MPPT solar charge controller varies continuously to get maximum amperes into the battery. Power point tracker is a high frequency DC to DC converter that takes DC input from the solar panels, then converts the DC into high-frequency AC and, again the AC will be converted back into a different DC voltage and a current to accurately match the batteries and panels.Report Download.

Wave Generator. Resistors and capacitors values can be adjusted to change frequency of three-phase sine wave generator. But to generate a clean sine wave without a lot of distortionyou need to update a lot more frequenclly than two points per Arduino Zero DAC Overview and Waveform Generator Example.

When the module is first powered up, it automatically outputs a default 1kHz sine wave. The max required peak to peak amplitude is 10V. However I cannot find a way to generate the right signal. Ahtisham Khan - 2 years ago. The programs will be similar with the ones in the sine wave post.

In this mode it continuously switches the output from low to high, making a square wave output.The process is controlled by the Arduino Nano board, which can find out the battery state and determine when the battery must complete the charging process. The state of the battery is perfectly controlled most of the time. The use of an Arduino Nano based on a microcontroller has been found correct to have adequate flexibility and simplify the hardware required only a few external components used by providing an intelligent tool to undertake programmed algorithm.

The proposed charge controller system can control the solar-powered system. In the future, this type of solar-powered system will reduce the consumption of paid grid electric power, which will minimize cost, and power optimization would be good. Renewable energy sources are natural resources such as sunlight, wind, rain, tides, and geothermal heat. These resources are renewable and replenished naturally. Therefore, these sources can be utilized inexhaustible for all practical purposes, unlike dwindling conventional fossil fuels.

The global energy crunch has provided a renewed impetus to the growth and development of Clean and Renewable Energy sources. Organizations are adopting CDMs all across the globe. Fossil fuels are rapidly decreasing globally. Another major factor working against fossil fuels is the pollution associated with their combustion. In contrast, renewable energy sources are much cleaner and produce energy. A Maximum Power Point Tracking algorithm is suitable for effective utilization of the solar panels.

This problem gets avoided in the Incremental Conductance method as the algorithm takes two samples of voltage and current to figure MPPT. So we have to mitigate with a trade-off between complexity and efficiency.

It has been observed that the efficiency of the system also depends upon the converter. Typically it is maximum for a buck topology, then for buck-boost topology, and minimum for a boost topology. It is straightforward to implement and has high efficiency both under stationary and time-varying atmospheric conditions. Initially, photovoltaic solar panels have been designed and used mainly for space technology applications, and the production costs of such panels were also very high.

As time passes, the photovoltaic cells were produced cheaper and cheaper, and their efficiency was also raised. This is also a reason why they are being used much more frequently, and it is not rare to see them on the rooftops anymore.Add the following snippet to your HTML:. Project tutorial by Saad Motahhir.
