Due to unlimited existence and environmental friendly nature, solar energy has drawn interest as one of the major sustainable energy resources. The challenge of reducing the cost of converting sunlight to electricity through photovoltaic cell lies in improving the efficiency of conversion. In this context, the solar tracking system plays a significant role for efficiency improvement. This work aims at design and implementation of a sensor-less dual axis solar tracking system based on solar sun chart program using Arduino Uno to capture maximum sunlight. Solar sun chart program predicts exact position of sun in a particular time by using latitude of a particular coordinate. With the help of solar sun chart algorithm, tracking strategy will be exact irrespective of nature. It can track sun in cloudy weather accurately. Two servo motors were used to rotate the panel according to the algorithm developed based on solar map in both horizontal and vertical directions. One motor was used to...

We are simply running out of fossil fuel. So in near or far future we must move to the use of renewable energy. Bangladesh is an agricultural country. A large amount of cattle dung, agricultural residue, poultry dropping, water hyacinth, rice husk etc. are available in Bangladesh which are used for power generation [1]. Biomass gasification, a new and promising technology of power generation in Bangladesh. Electricity generated from biomass gasification can be used for the purpose of rural electrification, one of the crying need of Bangladesh. Already some private organizations are producing power from the biomass. This paper includes availability, proper selection and quality of biomass throughout the country and utilization of by-product released by the plant. In this paper, a case study is incorporated on biomass gasification in Bangladesh to generate power from rice husk.

Two servo motors were used to rotate the panel according to the algorithm developed based on solar map in both horizontal and vertical directions. One motor was used to change the azimuth angle and the other motor to change the altitude angle. This improved control strategy known as open-loop control will reduce the complexity, cost and components required in comparison to a sensor based closed-loop control system. Our prime concern is to ensure the proper integration of all the electronic system in the mechanical hardware model and thereby develop an improved electromechanical system for solar tracking in photovoltaic applications.
