Solar Panel Tracking
As the earth moves through a yearly cycle (through the real solar system, that is), the angle of sunlight changes. To maximize your system output, you can track the sun as it changes position. You can purchase automatic solar trackers or you can track the sun yourself, by adjusting your solar panels accordingly.
Here's a rough guide as to how you might simply do that yourself:
- Early February: set your solar panel at the same angle as your latitude.
- Early May: set your solar panels at your angle of latitude minus 15 degrees.
- Early August: set your solar panel at the same angle as your latitude.
- Early November: set your solar panel at your angle of latitude plus 15 degrees.
Automatic solar tracking
For a more meticulously efficient solar energy system, you might look into purchasing an automatic solar tracker. These are solar "pathfinders" that follow the sun's daily path, to garner maximum power of the sun, for your pole mounted system.
For the vast majority of people, though, a solar tracker is only a neat "toy" you might buy for the fun of it and nothing else-the cost is not really warranted.
The best compensation for the problem of low sun angle is to simply purchase an extra panel.
