A solar tracking system (also called a sun tracker or sun tracking system) maximizes your solar system's electricity production by moving your panels to follow the sun throughout the day, optimizing the angle at which your panels receive solar radiation. Solar tracking systems do come with a high price tag. A smaller angle of incidence results in increased energy production by a solar PV panel. Adding more fixed panels typically provides better ROI than investing in tracking technology for most homeowners. Geographic Sweet Spot: Solar. . Solar panels generate the most electricity when they're pointing directly at the sun. There are two main types:. .
