The general rule for solar panel placement in the northern hemisphere is that solar panels should face true south (and in the southern, true north). . East-West Orientations Offer Strategic Value: While producing 75-85% of south-facing output, east and west-facing panels can provide superior financial returns by aligning with time-of-use electricity rates and matching typical household consumption patterns. Solar panels save you money on your electricity bills by producing electricity for your home to use.

Solar panels should face true south, not magnetic south. Use NOAA's magnetic declination calculator to find your local value and adjust accordingly. . The installation of a solar photovoltaic system involves many design choices, and the direction the panels face is one of the most fundamental. In the Northern Hemisphere, the long-standing guideline has been to position panels toward the geographic South to capture the greatest amount of sunlight. . Orientation refers to the cardinal direction your solar panels face (north, south, east, or west), also known as the azimuth angle. This tilt keeps the sun's path firmly in the southern sky throughout the day if you're in the Northern Hemisphere. However, a south-facing roof is by no means a necessity for a productive and economically viable solar power system.
