The optimal tilt angle for solar panels typically equals your location's latitude. For most of the continental United States, this means angles between 25-45 degrees. You can fine-tune this by subtracting 10-15 degrees for summer optimization or adding 10-15 degrees for winter. . Orientation refers to the cardinal direction your solar panels face (north, south, east, or west), also known as the azimuth angle. Here we have clearly detailed the steps you need to take to ensure the. . In general, solar panels should be installed so the sunlight hits them at as close to a perpendicular 90-degree angle for as long as possible during the day.
