Shipping Notice for 600W+ Solar Panels

All solar panels rated 600W and above exceed liftgate size restrictions and cannot be unloaded via liftgate. Residential deliveries require the customer to provide appropriate unloading equipment (forklift, skid steer, or equivalent) at the delivery location. Failure to provide equipment may result in re-delivery fees assessed by the carrier.
