Solar panels should face true south, not magnetic south. Use NOAA's magnetic declination calculator to find your local value and adjust accordingly. . One of the most common mistakes in solar panel installation is confusing magnetic south (what your compass shows) with true south (the actual geographic direction). This distinction is critical because: To find true south for your location: For example, if you're in Denver, Colorado, with a. . The installation of a solar photovoltaic system involves many design choices, and the direction the panels face is one of the most fundamental. However, a south-facing roof is by no means a necessity for a productive and economically viable solar power system.
[pdf] Solar panels should face true south, not magnetic south. Use NOAA's magnetic declination calculator to find your local value and adjust accordingly. Tilt angle describes the vertical angle of your panels relative to the ground, measured in degrees from horizontal. In the Northern Hemisphere, the long-standing guideline has been to position panels toward the geographic South to capture the greatest amount of sunlight. . As we increasingly rely on solar power, one question keeps popping up: Do solar panels have to face south? Solar panels typically face south in the Northern Hemisphere to maximize sunlight exposure and energy production. This fact was further emphasized by the 1991 Disney film Beauty and the Beast when Céline Dion and Peabo Bryson sang the lines, “Certain as the sun/Rising in the east.
