Quick Answer
To assess if your solar panels are correctly positioned, check if they are facing true south within 15 to 20 degrees east or west, tilted at an angle that matches your latitude, and positioned at a height of at least 4 feet off the ground.
Understanding Solar Panel Orientation
Solar panels should ideally face true south, as this orientation receives the most direct sunlight throughout the day. If your location has a mountain or a building blocking the southern direction, consider positioning them 15 to 20 degrees east or west. This slight deviation from true south can still provide excellent energy production.
Tilt Angles Based on Latitude
The tilt angle of your solar panels should match your location’s latitude to maximize energy production. A general rule of thumb is to tilt the panels 1/2 to 1/4 of an inch per degree latitude. For example, if you live at 35 degrees latitude, the tilt angle should be 17.5 to 22.5 degrees.
Measuring and Adjusting Panel Position
To ensure proper positioning, use a level and a compass to verify the panels are level and facing the correct direction. For accurate measurements, use a string or a stick to mark the location of the panels. Measure the distance from the string or stick to the south direction, and adjust the panels accordingly.
