By an utility approved qualified individual. The utilities really hate it if their maintenance people working on the power lines gets electrocuted because some solar powered inverter didn't shut off when they shut the line off.
That would depend on the panels themselves. There are many different specifications when it comes to panels, but if you wanted to be technical, just about any would give some impact - even if it were only a few cents.
I just costed an 85W panel I found online as paying back in 30 years. And that's without the inverter. If you want to do it to save money, look on surplus sites for chipped cells and make your own panels. You can then get the pay back time down to about 5 years, even with the 9.60/kWh price here, which is lower than many places.
Typical solar panels used on household systems generate between 00 and 50 watts each. You might get the equivalent of five hours of sunshine per day on the average. 500 to 750 watt hours per day would be the average output. Where I live that would save only about six to nine cents per day.
