Situation: 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. Question: 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. Thanks in advance.
