It is important for proper system operation that the solar panel is oriented to
TRUE SOUTH
. The directions of magnetic South and TRUE South differ from one
another depending on geographic location. The map below shows the difference between magnetic south and TRUE south for your area.
These charts should be used only for estimates. Solar systems can vary from this information. These maps do not take into
account small climate changes and may not be 100% accurate for all locations.
It is simplest to mount the solar panel at a fixed tilt angle and leave it (Shown on chart below). To capture more energy from the sun,
you can adjust the tilt angle of the solar panel twice a year (At the beginning of summer and winter). Add approximately 6° in the
summer and subtract approximately 6° in the winter from your “general” tilt angle on this chart. Your tilt angle may vary from this.
