First decide what you need the lighting for and where it should be
installed. If safety and security are you primary motivations, then you
need reliable "always on" lighting at night. Solar lighting may not be
a good choice because the lights only operate until the battery runs
low. But if you just want accent lighting for esthetic purposes such as
around seating areas, pools, ponds, trees or other landscape features,
then solar lighting is a great option.
