Solid product but needs improvement in the mounting bracket supplied for the solar panel. Bracket is difficult to attach to solar panel when the bracket is mounted to wall first. Bolt, washer and nut hard to install with recessed lip on solar panel. Rivnut on solar panel or bracket would resolve this issue. Attaching bracket to solar panel before installation makes it hard to install bracket to wall with depth of battery behind solar panel. Bracket should have pre drilled holes for fasteners. Lastly plastic protective wrap on solar panel is extremely difficult to remove and wastes installers time unnecessarily. Other than that product looks good and functioning well on installation.
