the decision on whether to utilize existing conduit and pull a new wire using the existing cable. It requires burying that conduit that roots brought up. He liked that idea better than a new cable through the house to a point within 25 feet of the garage. Busting the granite that we have here is not an option so if the existing plastic conduit cannot be buried to depth the only options are a steel conduit that only needs 6 inches or go through the attic and across. Thank you all, it helped direct the discussion with the solar contractor. Dan
