OPEN or DOWNLOAD the Excel spreadsheet. The first is the optimal direction for solar panels. If the sun is low in the sky, the air mass number will be greater than 1 since the angle causes the sun to pass through more atmosphere, resulting in a loss of solar insolation. The altitude angle () is determined by measuring the angle between the sun and the local horizon directly beneath the sun. If your location is in the northern hemisphere, the latitude would be measured in degrees north, for example, Los Angeles is at 34.05 N. On the other hand, in the southern hemisphere, the latitude is measured in degrees south, for example, Sydney is at 33.87 S. For the north, we enter positive latitude, e.g., 34.05 for Los Angeles.
