Abstract :- This paper presents efficient solar tracking
To rotate the appropriate position of the panel, a DC geared motor is used. The system is controlled by DC-geared motor driver and a microcontroller as a main processor [2].
system. The solar panel is parabolic in shape and based on follows scheffler dish principle. Parabolic solar collector is made by using polished Al specular sheet material. Due to parabolic shape of dish, maximum area of solar panel is exposed to solar radiation.LDR and DC motor have been selected as driving mechanism of the system. In this project the one movement of panel / horizontal tracking (E-W) is done automatically and another movement (N-S)/vertical tracking is done manually. The system have increased efficiency and reduced cost so that it can be implemented mainly in rural area.
A microcontroller adjust the structure position (inclination and direction) according to information gathered by sensors, and thuscontrolling the motor. By using this technique, the system have good accuracy[4].
SURVEY:
J.Rizk,et.al.[1],Presents ”Light sensor for Solar Trackers, a way in which the efficiency of solar power collection can be increased. It is to increase the efficiency of solar power conversion by increasing the amount of time that the solar panel is directly perpendicular to the sunlight. Efficiency is based on accurately positioning the solar panel throughout the day and thus stepper motors and Light Dependent Resistors (LDR) have been selected as the primary driving mechanism of this system .
Key Words: solar tracker, LDR, Scheffler dish, DC motor
INTRODUCTION : The Global warming has increased the demand and request for green energy produced by renewable sources - like solar power. As India has tremendous scope of generating solar energy. Since majority of the population lives in rural areas, as 72% population living in villages and half of the villages remain without electricity so there is much scope for solar energy being promoted in this area. It’s high time, that we should concentrate more on energy efficiency, conservation and renewable energy for that the solar tracking should be effective .There are two main ways to make the solar cells more efficient, either by improving the actual cell or by installing the solar panels on a tracking system that follows the sun [1]. Solar tracker is an automated solar panel that actually follows the Sun to increase the power. The sun's position in the sky varies both with equipment over any fixed position [2]. The solar panels must be perpendicular to the sun's rays for maximum energy generation. Deviating from this optimum angle will decrease the efficiency of energy generation from
In [8] Chih-Wei Chien1,et.al.Presentsa new microconcentrator architecture based on origami concentrators is proposed for plate-plate photovoltaic applications to potentially lower the cost of electricity. The fabrication of the concentrators adopts the origami technique, allowing the use of thin-film processing technologies. The concentrators are lightweight, flexible, and requiring only aonedimensional translational motion for solar tracking. Mayank Kumar Lokhande,[2]Presents The main objective of this project is to development of an automatic solar tracking system whereby the system will caused solar panels will keep aligned with the Sunlight in order to maximize in harvesting solar power. The system focuses on the controller design whereby it will caused the system is able to tracks the maximum intensity of Sunlight is hit. In[9] A Two-Axis Soft Robotic Platform for Solar Tracking and Building-Integrated Photovoltaic Applications. This paper present SoRo-Track, a two-axis soft robotic actuator (SRA) for solar tracking and building-integrated photovoltaic applications. SRAs are gaining increasing popularity comparedto traditional actuators, such as dc motors and hydraulic or pneumatic pistons, due to their inherent
the panels [3]. LDR or light dependent resistor has been chosen as the sensor because LDR is commonly used in sun tracking system. This is because LDR is sensitive to the light. The resistance of LDR will decreases with increasing incident light intensity.
