Point the panels magnetic-north and adjust 11° west to achieve True North and the perfect azimuth angle. The azimuth angle ensures solar panels point directly at the equator. Positioned to attract as much sunlight as possible, they maximize yield potential. Generally, in the Northern Hemisphere, the ideal azimuth is 180° (true south), and the best fixed-tilt angle is equal to the site's latitude. However, this is just a baseline. True performance. . This calculator use a series of global models that will calculate your optimum annual tilt angle based on your latitude and your local climatic conditions. Based on the data of +14,000 sites spread across the globe from the One Building database. Let's start with two key terms:. .
