7. How should I handle logistics and shipping for my order?
   Logistics can be complex, especially for international shipments. Coordinate with your supplier on shipping methods, insurance, and customs requirements in your country. Consider working with logistics companies experienced in handling solar panel shipments to minimize risks of damage. Confirm that the supplier provides adequate packaging to protect panels during transit. Additionally, track your shipment and maintain communication with your supplier to address any potential issues proactively.

8. What steps should I take if a dispute arises with my supplier?
   In the event of a dispute, first, communicate directly with the supplier to seek resolution. Document all correspondence and agreements to support your claims. If discussions fail, refer to the terms outlined in your contract regarding dispute resolution. Many contracts include mediation or arbitration clauses, which can be a less confrontational method of resolving issues. If necessary, consider seeking legal counsel familiar with international trade laws to explore your options.
