I wouldn't waste my money on solar panels. They are a piece of crap. Just drive around your neighborhood and look at people that have solar panels vs. those with wired lights. Solar panels never give off much light and are usually bulky.
I have wired my whole house with landscape lighting. Anyone can wire them once you learn how, but if you've never done this nor have the time to learn how, I would consult a professional landscape lighting company. If you want details on how to do an install or help, message me. There's actually a lot of planning that goes into doing a lighting project for your home and if you're not careful, you can make some mistakes which will cost you money.
