More vitality is obtained by tracking the solar panel, by placing the panel remains related to the sun at a right edge to the beams of light. It illustrates the point of interest of outline and development of a model for solar tracking system with two degrees of opportunity, which recognizes the sunlight by means of photocells. The control circuit for the sun powered tracker depends on a PIC16F877A microcontroller (MCU). This is modified to recognize the sunlight through the photocells and afterward trigger the motor to position the solar panel where it can get most extreme sunlight. Index Terms: MPPT, Solar Tracking Method, Inverse SEPIC Converter, LDR. I. Introduction Introduction to Inverse SEPIC converter in MPPT allow us to use of new possibilities in efficient software controlled power supplies. In several markets, demand is increasing for well-organized non-inverting dc/dc converters that can control the operation either in buck or boost mode, decreasing or increasing the input voltage to a desired synchronized voltage with minimum cost and component count. The purpose we are using has covered 100W inverse SEPIC (single ended primary inductor converter ) are also called as zeta translator. The inverse SEPIC is a charge controller. The uniqueness consists of driving the topology synchronously using microchip components, approaching the efficiency over 95% at 6A. The zeta converter has several advantages like input to output DC insulation, buck boost capacity and produce the constant output current (Iout), but it is not easy to control. The compensation of the new inverse SEPIC translator is one and the same as buck boost functionality as the SEPIC, but the continuous output current provided a clean, low ripple output voltage. This low-distortion output translator can be used to control certain types of load such as LEDs which are receptive to the ripple voltage. The zeta translator offers the identical DC isolation between the Input and Output as the SEPIC translator and can be used in high reliability system. I. 2. Solar Tracking Method The Sun Monitoring System (SMS) was able to programmed and place the panel perpendicular to the direction of sun as far as the intensity of light is visible. The selective component of the system is that it must suppose to choose the sun as controlling source rather than the earth as its reference. Their dynamic sensors continuously observe the light intensity and tilt the panel almost near the path where the intensity of light is at its peak level. In the event that the sun gets undetectable e.g. in shady climate, then without tracking the sun, the SMS continues to rotate the panel exactly in opposite way to the rotation of earth, until its rate of rotation is similar to that of earth's rotation. Due to this property while after some time e.g. 30 minutes when the sun again gets visible, the PV panel is accurately in front of the sun. 2.1 Need for Solar Tracking Method Comprehensively temperature alteration has expanded the interest and asks for environmentally friendly, essentiality of power energy acquired by the renewable energy sources like solar power. The end user would incline towards the tracking system rather than a fixed ground system. Since:  The proficiency increments by 30 to 60%.  The space essential for a sun oriented recreational zone is diminished, and they keep the same amount of productivity.  The event of return venture is decreased. Checking the direction of sun from east to west will resolve the proficiency of the solar power by 30 to 60% depending upon whom you ask and where you are in the world. Near the equator, you could have the maximum advantage from monitoring the sun.
