Landscape lighting adds value to your yard by highlighting prized plants, water features, pathways, patios and benches. This proves helpful when you and your family members spend time outdoors in the evening, as the lighting provides orientation and outlines safe walkways, keeping your children from straying into flower beds. Solar-powered landscape lights also negate the need for cords and outlets, preventing injuries from tripping and allowing you to position lights throughout your garden. A few simple adjustments will brighten waning or noticeably dim solar landscape lights.
Examine the solar panel on each light fixture looking for debris that blocks the sunlight from reaching it. Brush off any leaves, seeds or other loose material resting on top of the panel. Pour 2 cups of water and 2 to 3 drops of dish soap into a small bucket. Dip a rag in the soapy water. Wring the rag out until it remains moist but stops dripping. Wipe the rag gently across the surface of the solar panel, removing any clinging dust and grime. Blot the solar panel dry with a second, dry rag.
Check each solar light once an hour for at least eight hours during a bright, sunny, cloudless day to see if the light remains in full, direct sunlight. Move the solar lights that become exposed to shade at any point during this time, placing them in an area that receives at least 8 hours of direct sunlight.
Unscrew the screws from the battery cover panel on the solar light using a screwdriver. Remove the panel and set it aside. Pull out the light's batteries. Place new solar light batteries into the light's housing. Ensure that you have placed the batteries with their positive and negative ends in the correct position. Put the battery cover panel back in place. Place the screws in their respective holes and tighten them with the screwdriver.
