Solar trackerQ: How solar tracker works? A: Trackers direct solar panels or modules toward the sun. These devices change their orientation throughout the day to follow the sun's path to maximize energy capture. Because these trackers follow the sun vertically and horizontally they help obtain maximum solar energy generation. Q: Why do we need solar tracker? A: A solar tracking system maximizes your solar system's electricity production by moving your panels to follow the sun throughout the day, which optimizes the angle at which your panels receive solar radiation. The narrower the angle of incidence, the more energy a photovoltaic panel can produce Q: Do solar panels move? A: Tracking systems move the panels throughout the day in order to keep them facing the sun. The longer they are aligned with the sun, the more energy they can produce – or at least that is the idea behind them. In reality, however, moving solar panels may not be the most practical choice for many homes and businesses.
