How do I care for and clean the solar panel on the Brightown HLS-W-XXXWW-S?
For optimal performance, wipe the solar panel once a week with a moist cloth to keep it clean. You should also avoid placing the panel in shaded areas and adjust its position seasonally to account for changes in the sun's path. (Page 6)
