We are responsible for transporting the goods to your logistics agent. They have inspected and signed for the goods, which proves that our goods were intact when they arrived at your logistics agent's warehouse. The cardboard box on the solar panel can only move horizontally and cannot sway up and down at all. Because the wooden frame is blocking the space.The cardboard box will not damage the solar panel.The damage to the solar panel must have come from the outside. If it is the freight forwarder we provide, we will bear all costs. Before our delivery, all goods were in good condition and there were transportation warning signs and fragile labels on the packaging. It is obvious that your logistics company engaged in illegal violent transportation, and the responsibility does not lie with us. Please rationally distinguish the responsible parties Although the responsibility does not lie with us, we are willing to offer you a certain discount for our next cooperation.
