Thank you very much for bringing this to our attention. There was a mix-up in our online listing: we incorrectly posted information from our smaller 3-piece battery-operated skeleton set on this product page. We have since updated the description to state clearly that this item requires a power plug to operate; only the remote uses batteries. We sincerely appreciate you flagging this issue. Your feedback helps us avoid similar misunderstandings for future shoppers.

Thank you for your feedback! This item features color‑changing LED light strips which draw relatively high power. Unfortunately, solar power cannot adequately support this function, and it would require an overly large solar panel to work properly.The transformer plug and fixed plastic screw cap are designed for safe outdoor use.
