Assuming you would like a step-by-step guide on how to install solar lights in hard ground:
1. Begin by finding an area in your yard that gets direct sunlight for most of the day. This is important because solar lights need direct sunlight in order to work properly. Once you have found the perfect spot, use a garden hose or some other type of marker to outline where you want the solar lights to go.
2. Next, dig a small hole at each mark that you made in Step 1. The holes should be about 6 inches deep and 6 inches wide.
3. Now it’s time to put the solar lights into the holes. Make sure that the solar panel on each light is facing up so that it can get direct sunlight. Also, make sure that the light is pointed in the direction that you want it to shine once it’s installed.
4. Once all of the lights are in place, fill in the holes with dirt and pack it down tightly around each light. Again, make sure that the solar panels are facing up and not buried under dirt or grass clippings.
5. Finally, give each light a few taps with a hammer to make sure that it’s secure before stepping back and admiring your handiwork!
