What do I do if the solar panel on my garden or patio light looks cloudy/dirty?Adam
Dirt and dust will accumulate on lights over time and if the solar panel becomes blocked it can affect the output of the panel. This can normally be dealt with by wiping the panels clean. The solar panels on small garden lights may also naturally cloud over time, especially when stored in the warehouse for extended periods of time. Lights should still be charged and tested, as in many cases it will not affect the operation of the light. If the light functions properly, cloudiness can sometimes be removed by a thorough cleaning of the panel, by applying a layer of clear lacquer finish, or by applying a layer of clear nail polish directly to the solar panel.
