These embedded applications are required to collaborate with the other components of an enclosed system. Embedded application components interact mostly with the non-human external environment.

They continuously collect data from sensors or other computer components and process data within real time constraints. Embedded systems are usually associated with dedicated hardware and specific software. The system is focusing on the controller design. The constructed system has been tested and some data from hardware measurement have been collected and discussed. Typical solar panel has been used and the purpose only to prove the designed system is able to operate accordingly.

Therefore the surrounding effects, for instance, weather condition are not seriously considered during hardware testing. Solar tracking systems are used to continually orient photovoltaic panels towards the sun and can help maximize your investment in your PV system. | Photovoltaics | Solar Energy

They are beneficial as the sun's position in the sky They can be used most effectively in areas with low horizons and locations that are shade free from dawn to dusk each day. Throughout the year the tracking array will be able to utilize the wide open access to gain every available electron from the sun.

This way, energy production is at an optimum and energy output is increased year round. The standalone PV home kit system is a very reliable and uncomplicated source of energy production; the panels don't move and require little maintenance.

They are beneficial as the sun's position in the sky will change gradually over the course of a day and over the seasons throughout the year. Advantages to using a tracker system like this will depend mainly on it's placement in determining how well it will increase the effectiveness of the panels.

This is especially significant through out the summer months with its long days of sunlight available to capture and when, at many Northern latitudes, the sun rises in the northeast and sets in the northwest, no energy will be lost.

For those with limited space this means that a smaller array only. High cost during development, difficult to control motor speed and difficult to design. By adding a solar tracking system to your solar panels, we are adding moving parts and gears which will require regularmaintenance of your solar system and repair or replacement of broken parts.

If we are electronically controlled tracker stops working and you don't have a manual control, an option you can choose at the time of purchase, you can manually position your array to solar south to ensure that you will continue to capture as much solar energy as possible. Solar tracking systems do not come without their disadvantages though.

Secure the array into place with ropes or straps found on the Another possible disadvantage to be aware of when purchasing a tracking solar power system, is in the way your local utility's PV Rebate Program may be set up. Many are based on the size of the PV array in your home kit and not on your PV array's production, which could mean less of a financial benefit to you. If you have a small array, such as a 3 Watt capacity, you may get less overall cost benefit than someone else with a larger array of a Watt size capacity, even if your energy production works out higher than the person using a bigger array, due to increased sun exposure in your area.

The upfront cost of purchasing a home kit with a smaller size array is less but you may receive a smaller rebate check. Many areas though, are now starting to make the move from the rated wattage system of photovoltaic home systems to the energy production based incentive program.

It controls movement in azimuthal and zenithal directions, independent of whether the requirements are for a photovoltaic PV or a concentrated solar power CSP facility. The modules or mirrors are optimally aligned with the angle of the sun's rays to constantly optimize solar energy regardless of the suns position. These solar tracking systems have up to a one-third higher energy yield than stationary PV system depending on the intensity of the sunlight at the installation site because the closer an installation is to the equator, the more.

Applications in concentrated solar power and concentrated photovoltaics require the precise tracking of solar units to focus sunlight on the target medium. Solar trackers are devices used to orient photovoltaic panels, reflectors, lenses or other optical devices toward the sun. Since the suns position in the sky changes with the seasons and the time of day, trackers are used to align the collection system to maximize energy production. Several factors must be considered when determining the use of trackers.

Some of these include: Solar panels are usually set up to be in full direct sunlight at the middle of the day, facing south in the Northern Hemisphere, or facing north in the Southern Hemisphere.

Therefore morning and evening sunlight hits the panels at an acute angle and reduces the total amount of electricity which can be generated each day. A solar tracker is a device onto which solar panels are fitted which tracks the motion of the sun across the sky, thus ensuring that the maximum amount of sunlight strikes the panels throughout the day.

When compared to the price of the PV solar panels, the cost of a solar tracker is relatively low. We provide highly efficient, proprietary single and dual axis solar tracking systems. Construction of this project is very easy. Make the all connection on the PCB Board as given in the circuit diagram. Assemble and solder all the components as given in the circuit diagram. Check the Continuity of the tracks on the PCB board with the help of Multimeter setting on the continuity mode.

Check the Voltage on the all IC pins with the Mulitimetre by setting multimeter on the 20v dc. Check the serial communication on the PCB board by using serial cable with the pc by hyper terminal or using Terminal Software. Single Axis Solar Tracking System prototype model is successfully developed. The designed system is focuses on designing controller part and the main concern is to design appropriate circuits and the circuits suppose to be able to control DC-gear motor rotation direction without considering motor speed.

The system is able to track and follow Sunlight intensity in order to collect maximum solar power regardless of motor speed. The unique of developed system, motor speed is not critical consideration Therefore any types of DC-geared motor can be used for this system regardless of motor speed controller unit as long as the speed and torque of the motor are following the given specification.

The constructed system model can be applied in the residential area for alternative electricity generation especially for non-critical and low power appliances. David Appleyard, Solar Trackers: Ralph Boon, June 1, Flag for inappropriate content.

Although there are many solar trackers in the market, the price is expensive and unaffordable because the market for solar tracker is still new and only certain countries use the solar tracker such as USA and South Korea.

Working tracker: And the other is the principle on which the solar panel works, which is on the incidence of the solar rays the photovoltaic cells, will produce electricity. Component Required: For those with limited space this means that a smaller array only needs to be installed, a huge advantage for those smaller sites with only a small area to place equipment; they will be able to produce maximum energy output but only need to utilize one of the smaller solar home systems.

These solar tracking systems have up to a one-third higher energy yield than stationary PV system depending on the intensity of the sunlight at the installation site because the closer an installation is to the equator, the more efficiently the PV tracking systems operate.
