This paper describes the behavior of adaptive control using the MIT rule for a polar aligned single axis tracking system, it´s for increase the efficiency of solar energy capturing compared to a polar fixed system, where the response of system is analyzed by simulation in Simulink – MATLAB® software. The data input for estimate the energy in the photovoltaic panels is the radiation data, that is obtained by weather station of the CAR (regional autonomous corporation) situated in the zone of study. The objective of the integration between the photovoltaic panel and the mechanics tracking system is to keep the perpendicular sunlight during the day. The MIT adaptive control tries to reduce possible errors, such a sun position data deviations, friction and environmental changes in the conventional solar tracking. This control was designed according to a typical polar aligned single axis tracker.

Energy Independence

Solar trackers are rising in popularity; they benefit a wide range of applications since distributed solar energy generation can reduce electricity costs and support energy independence. In this paper, a simple solar tracking system is introduced. The system is a package unit that can be mounted on any solar panel. The system consists of an electrical motor connected directly to a sliding mass on a linear bearing. The electrical motor is controlled to slide the weight along the shafts in controlled steps. As a result, the photovoltaic panels are rotated automatically under the effect of controlled weight unbalance in fine angle increments to track solar trajectory without the need for traditional complex or costly mechanisms. Two light dependent resistors (LDR) sensors, mounted onto the surface of the solar photovoltaic panel, are exposed to solar irradiance and used to feed signals to a controller. A model of the solar tracking system is developed using ordinary differential equations, and numerically solved by MATLAB/Simulink™. The power consumption and tracking strategy of the proposed tracking system are estimated under realistic operating conditions (e.g. wind and brakes), and the power consumption is compared to the power generated by the photovoltaic panels. Optimum values for the sliding mass are suggested. Two photovoltaic modules are used to calculate the output parameters of the proposed tracking mechanism.

Previous studies have highlighted that fossil fuel accounted for the largest share of total energy consumption in worldwide if compared to renewable energy. However, it has many disadvantages such as emission of carbon dioxide gas, contributes to global warming, creates pollution, contributes to acid rain and unsafe. Nowadays, many solar power plants have been built in order to replace fossil fuel. Solar energy has bright future due to some advantages such as pollution free, cheap renewable energy, easy install solar cell panel and less maintenance. Solar photovoltaic development has remarkably grown since the early 2000s. Because an average panel lifetime is 30 years, 17,000 tonnes of solar panel wastes are anticipated in the year 2030 in Malaysia. As the solar photovoltaic market increases, so will the volume of decommissioned photovoltaic panels. Growing photovoltaic panel waste represents a new environmental challenge, but also miraculous opportunities to create value and pursue new solar photovoltaic end-of-life industries economic route.

Solar Tracking

The paper outlines an application of smart solar “photovoltaic” power generation. Solar panels are typically in fixed position. They're limited in their energy-generating ability because they cannot consistently take full advantage of maximum sunlight. For more effective solar energy system, the solar panel should be able to align with sunlight as it changes during a given day. The present paper examines the design advantages of creating an intelligent solar tracking system like a helianthus flower using microcontroller based embedded system.
