How can I choose the ideal location for the unit?

The ideal conditions for the site pad should consider the following:

1. The site surface should be high-quality permeable, or impermeable hardscape.
2. Slope is maximum 2°. 
3. If the slope is greater than 2°, possible site leveling measures should be discussed.
4. The ideal site will have unobstructed solar access with southern orientation.
5. The site should be free from substantial shade from 9am to 3pm.
