In general, solar energy is widely regarded as being an incredibly energy efficient lighting source. After all, it makes perfect sense as it does not use external electricity and merely converts the power of the sunlight into electricity. Past this, though, when choosing solar lanterns for your yard, their installation is also a breeze. There is no external wiring to mess around with, after all, and all you need is sufficient sunlight. In a sense, you could also consider this type of lighting safer because of it.
