For warranty replacements, please send an email to info@tenkoosolar.comfor complete instructions. If approved, our team will issue an RMA (Return Merchandise Authorization) and replacement product will be sent out upon receipt of the defective units. TENKOO will either replace or repair the defective unit based upon our discretion. Items returned without an RMA number will be rejected and returned to sender. Customers requesting an advance replacement will be required to provide payment information for a replacement unit which TENKOO will keep as a pending charge for the original cost of the item. Once we receive the defective item, the unit will be examined for accessories and physical damage. If after review all accessories are present and the unit is in “good” condition, then the pending charge will be voided.
