<DIV>Situation:</DIV>
<DIV>ROCK - limestone ledge on cliff. Surface is relatively smooth with little
to no grade in a 30' x 30' area. Basically a large slab of limestone about
4' thick.</DIV>
<DIV>Question:</DIV>
<DIV>Anyone have experience with some type of ballasted mount system for
either fixed or tracked array in this type of environment? Boring
holes will be very expensive. I've seen the precast bell shaped
ballasting on commercial projects, wondering if there is a way to do that on
residential size array of 5 to 10kw.</DIV>
<DIV>Thanks in advance.</DIV>
