Solar energy, Photo resistors, Solar panel and ARDUINO
The aim of this paper is to solve the problem of energy crisis which is considerably serious issue in today’s period. It is becoming essential to increase use of renewable sources of energy namely solar energy as compared to conventional sources for energy generation. A technology namely automatic smart sun tracking and cleaning system for solar panel using motor mechanism and arduino controller introduced to improve efficiency of solar cells by tracking and cleaning system sun’s energy. It uses arduino microcontroller and stepper motor to move solar panel according to position of sun. Photo resistors are also used to detect light intensity.
