Yes, a 1W solar panel can charge an 18V battery. It requires proper voltage conversion and a charge controller. The panel should ideally output around 21V. Ensure the battery has enough capacity to store the charge. Use a charge controller to prevent over-charging and protect the battery from damage.
[pdf] What is the normal current of a 30 watt solar panel? The normal current of a 30-watt solar panel typically ranges from 1.5 to 2.5 amperes, depending on various factors, including the specifications of the panel and environmental conditions. 1.
