Abstract
Sun tracking systems comprise of automated panels that follow solar emissions in order to achieve an optimal angle between radiations emitted from the sun and the solar panel. Once an optimal angle is identified, efficiency and the maximization of energy production can be achieved. Due to various locations of the sun, solar panels’ efficiency and energy production are constrained. Therefore, in order to maximize the optimal angle, a dual axis tracking system designed to capture solar radiation will ensure that the solar panels maintain a perpendicular direction to the sun. The purpose of this thesis study is to design and simulate two slew drives that rotate the solar panel vertically and horizontally. In addition, material compression was conducted to select an optimal material with a minimum factor of safety of 2 which withstand the gust (wind) force in Connecticut. Our research determined that AISI 1050 Steel is the best material for the slew drives with a safety factor greater than 2 that can withstand the gusts during hot and cold weather conditions in Connecticut.
