It’s recommended to set the deck lights in a place where they receive plenty of sun each day. It’s important to take seasonal changes into account when determining the placement of your solar panels. When it comes to height, we recommend mounting the deck lights at a 7ft or 8ft to make sure the sensor can read motion sensing. However, there are cases where customer install the lights on the ground and that can work as well. Just make sure the solar panel is receiving plenty of sun.
