billvon is right, All UL solar panel come with ground connection hole, Just connect them together and ground it to ground, do not ground it to your power line, Ground it to ground directly either "Copper rod" " Metel water pipe", not very much work.
In My area, Our electricity rate is 6 cents only, I installed 1/3 size of my 5KW system and decided to wait awhile for better timing, It does need cleaning occasionally here due to dust problem unless you install them more vertical.
I also installed a small testing 400W Wind turbine, It was even worse Idea here because of higher maintenance and noise problem with expensive strong mounting system needed. ( For winter time power)
They are investment, I find that it looks $100 project but it is easily end up $10,000.
