How to Convert an Electric Outdoor Light to Solar | Sciencing

Solar Panels – Virtually any solar panel with an output of 5 watts or more will charge the battery, but larger panels charge the battery more quickly, and that's important. If you have a 150 Ah battery and get about eight hours of sunlight a day, the panel output should be at least 120 watts to ensure the battery charges fully during the day.
