So you have (6) 240W panels, we can certainly help you mount those. Up to now, we haven't seen the appeal of the I beam products for residential use, and they have changed this product several times since it came out. Initially the span ratings were very low, maybe they have improved that. Do you have to use the I beams? What lengths of rail do you really want? Feel free to contact firstname.lastname@example.org
or 970-984-3750 and we can quote something delivered. I would suggest waiting a bit for a ski trip - not much snow yet.
