i also had no experience with anything electrical either. spent a few weeks reading up over in the LED section and deciding what build i wanted. its really a pretty simple process once you know whats going on. though i certainly recommend putting in the due diligence before diving in, the performance is well worth it.
when i finally got all my stuff i had a buddy whos an electrician come over to help put the first one (200w panel) together. he was pretty well shitfaced, couldnt grasp the concept of connecting the drivers negative to the COB's negative connection rather than positive, asked no less than 10 times "so this little yellow thing is the light?" , hand was wobbling all over the place so i had to take the soldering iron away from him before he melted a hole through one of my COB's.
