Currently most of my lighting is driven by low voltage power or by 110 AC. However I was wondering if anyone has tried using mostly solar lights. I see advantages and disadvantages of each but I wanted to start a discussion. Powering the lights with Low voltage or AC requires many more wires but does mean I can turn on everything all at once. I also do not have to be concerned with overcast days leading to not enough power for the solar cells. Of course the solar lights would eliminate the wires and simply turn on once it is dark enough. What are other people's feelings on these. I am particularly curious to hear from people that use lots of solar powered lights.
