If you solar light fixture does not turn on at night, check for the following conditions before ordering replacement parts:
Battery is not fully charged: Make sure the fixture is placed in an area where the solar panel gets the maximum amount of full, direct sunlight everyday. If the solar panel does not receive enough sunlight during the day (e.g. due to cloudy or overcast weather conditions), it will be recharged on the next sunny day and resume operation. Other light sources: If the solar panel is located too close to street lights, porch lights or other lights, the photocell (light sensing device) may turn off the fixture. Relocate the fixture or eliminate those other light sources. Direct Sunlight: Ensure that the solar panel is not installed in a shady area, for example, in the shadow of a tree or a house. If necessary, move to an area that gets full direct sunlight. Batteries may need replaced: Batteries need to be replaced each year for optimum performance. Always replace with new rechargeable batteries with the proper rating. Do not use non-rechargeable batteries.
