That really doesn't make sense. How the job is charged, doesn't change how long it takes. Are you suggesting that they are giving the labor away by charging by the job? The employees are paid by the hour and unless they take shortcuts, aren't going to be more efficient and get more quarter panels done in a week if they charge the customer by the panel instead of by the hour. I guarantee they are making sure that they cover all the potential hourly wage and consumables costs plus some, by baking it into a generic job charge. So it actually costs the customer more in the end if they are in fact doing it that way.
