Harnessing Maximum Solar Power using Arduino Control

With the approaching inadequacy of nonrenewable resources, people are considering using alternate sources of energy. From all alternative obtainable resources energy from the sun is the most extensive and it’s relatively serene to convert it to electrical energy. Use of solar panel to convert sun’s energy to electrical is incredibly widespread, however owing to transition of the Sun from east to west the mounted solar panel could also be able to generate optimum energy. The projected system solves the issue by an arrangement for the solar panel to trace the Sun. This paper relies on the utilization of solar panel coupled to a servo motor to trace the Sun so most sun light is incident upon the panel at any given time of the day and year. This can be higher compared to mounted panel technique which may not be thus economical. Moreover, the code is built using C++ programing language and targeted to Arduino UNO controller. The efficiency of the system has been tested and compared with static solar panel on many time intervals, and it shows the system react the most effective at the 10-minutes intervals with consistent voltage generated. Therefore, the system has been proved to be operating for capturing the utmost sunlight source for prime efficiency solar gathering applications. Moreover the work may be increased by using RTC (Real Time Clock) to follow the Sun. This helps in maintaining the specified position of the panel although the power is interrupted for some time.
