  • Solar tracking system in real time including a light-resistant box with a loophole at a top surface being smaller than each convex lens in a conex lens plane array located within the light-resistant box
    Patent number: 9354294
    Abstract: A real-time solar tracking system includes: a microcontroller, a light-resistant box, a motor for changing a direction angle of a solar collection board, and a diver for controlling operating condition of the motor. The light-resistant box has a loophole disposed at a top surface of the light-resistant box, a convex lens plane array is disposed parallel to a bottom surface of the light-resistant box, and a photosensitive element array is disposed at a bottom of the light-resistant box. The microcontroller is used for calculating a solar direction angle according to a solar direction angle signal obtained from the photosensitive element array, and sending directions to the driver. With advantages of high detecting accuracy, high degree of automation and intelligence, well environmental adaptability, high reliability, low cost, the present invention is particularly suitable for solar power system.
