What solar incentives are available in California?

How long does it take for solar panels to pay for themselves in California?
Most California homeowners see a payback period of 5–7 years, thanks to high electricity rates, abundant sunshine, and generous incentives. After payback, you enjoy essentially free electricity for 20+ more years.
Is NEM 3.0 still worth it for California solar?
