All you need is your device, battery, and the panel. And you are set.

3. Outdoor Lighting Setup

Yard and fence lights around a huge area are always good for nighttime watch and activity. But again, wiring is the issue. Underground wiring does not come in cheap. And maintaining them is a whole different game. But having a solar panel powering them up is a lot less hassle-free and cost-effective.
