Unfortunately, the expense of a tracker means that for most applications they are more expensive than buying additional panels to compensate. Don't wanna mess with any solar tilt calculations? Also, the calculator does not give you the option to input seasonal or monthly tilt angle adjustments. If you do have a flat rooftop, do not despair, usually a mounting device is installed so as to deflect rainwater and allow the rain to clean the panels. For roof-mounted panels, it is difficult to use trackers. It can be used to determine the optimal angles to tilt your solar panel monthly and seasonally. The direction the panels are facing is vital too. Solar trackers are only viable on ground-mounted panels, which is not often the case in domestic use. Solar noon is the exact half of the day where the sun is at its brightest. In winter, the sun is low on the horizon and so the solar panels should be adjust to be more upright, closer to 90. A solar tracker is a system designed to do exactly that. When attached to a roof, they react with photons from sunlight to generate clean, safe, reliable power. Solar Resource Maps and Data. Now you should just make sure you get the maximum out of your investment, and that means adjusting the system in a way that will provide you with the best possible energy output.
