After paying in full, we are getting notices that the supplier Sun Valley was not paid by the installer Summerlin Energy. Can't get any call backs from Summerlin Energy. Our only defense are the cancelled checks to show that Sun Valley must go after Summerlin Energy. We are not going to pay twice and will fight any liens or attempts to lien us. As of this writing, we are still not hooked up to NV Energy's grid and the solar panels just sit up on the roof doing nothing.
