http://www.heliotrack.com/Solar-Ethanol.html A closer view shows that this hydro-thermal / photo-voltaic collector is nothing more than a ten gallon aquarium with a small solar panel submerged in the water in front of the black plate heating element. The solar cell is encapsulated in clear epoxy so it is waterproof. The surrounding water keeps the solar panel from exceeding 160°F. What we don't know is how long the solar panel will hold up under nine times concentrated solar power or '9X CSP'. The solar panel is powering a small gearmotor as a load test to simulate a recirculation pump. http://www.heliotrack.com/Applications.html

Archimede is a parabolic trough plant operating in Sicily, Italy. The plant produces steam (4.72-MW equivalent) sent to a combined-cycle steam turbine rated at 130 MW. This parabolic trough system is the first using molten salt as the heat-transfer fluid. A 2-tank direct system will provide 8 hours of thermal storage.

http://solarenergyengineering.asmedigitalcollection.asme.org/journal.aspx The Journal of Solar Energy Engineering The output power produced by high-concentration solar thermal and photovoltaic systems is directly related to the amount of solar energy acquired by the system, and it is therefore necessary to track the sun’s position with a high degree of accuracy. Many systems have been proposed to facilitate this task over the past 20 years. Accordingly, this paper commences by providing a high level overview of the sun tracking system field and then describes some of the more significant proposals for closed-loop and open-loop types of sun tracking systems.

https://www.hindawi.com/journals/ijp/2011/806518/ Pointing Sensors and Sun Tracking Techniques The Pinhole Sensor works as a pinhole camera without lenses. Figure 4 shows the main elements composing the Pinhole Sensor: pinhole and four-quadrant detector (4-detector).
http://www.ijcaonline.org/archives/volume31/number9/3965-5325 This paper presents the hardware design and implementation of a system that ensures a perpendicular profile of the solar panel with the sun in order to extract maximum energy falling on it. Renewable energy is rapidly gaining importance as an energy resource as fossil fuel prices fluctuate. The unique feature of the proposed system is that instead of taking the earth as its reference, it takes the sun as a guiding source. Its active sensors constantly monitor the sunlight and rotate the panel towards the direction where the intensity of sunlight is maximum. The light dependent resistor’s do the job of sensing the change in the position of the sun which is dealt by the respective change in the solar panel’s position by switching on and off the geared motor. The control circuit does the job of fetching the input from the sensor and gives command to the motor to run in order to tackle the change in the position of the sun. With the implementation of the proposed system the additional energy generated is around 25% to 30% with very less consumption by the system itself. In this paper, an improvement in the hardware design of the existing solar energy collector system has been implemented in order to provide higher efficiency at lower cost.

https://www.praiseworthyprize.org/jsm/index.php?journal=ireaco&page=article&op=view&path%5B%5D=13709 The tracker has two axes, X-Y Cartesian mechanical system to compensate the roll and pitch of the ship movement. The system uses four light sensors in obtaining the highest intensity to adjust the dish for pointing the sun position. A system simulator prototype was built to verify the proposed system. Gyrometers are placed on the ship simulator and dish to monitor the focus of the angle system. Result for the prototype shows that the control system is capable to track the sun under ship movement. The error of focus angle is under 3.707 percent error of roll and pitch disturbances.

https://www.youtube.com/watch?v=AHYCLvaeAbk This is my simple solar tracker, all you need is a charger 6 volt,timer for 1 minute, turning the system is simple and effective and proven to work,every 1 hour for 1minute solar tracker is moved by 30 degrees, was divided into 9 positions in 1 minute, to turn i use a DC motor with gearbox, it was too fast so I added my gear that I made from old gear to reduce the rotation speed for another 3 times so that the speed of turning panels is just right,after sunset i return panels back to the starting position,panels can be adjusted so that panels always provide its rated power
