Abstracts: A solar tracker is a device for orienting a day-lighting reflector, solar photovoltaic panel or concentrating solar reflector or lens towards the sun. The sun’s position in the sky varies both with the seasons and time of day as the sun moves across the sky. Since solar powered equipment works best when pointed at or near the sun, a solar tracker can increase the effectiveness of such equipment over the any fixed position, at the cost of additional system complexity.
