Multi-crystalline solar panels have an energy payback period of just 2 years.
Another favourable caveat to note is that value is based off an assumed solar panel efficiency of 14%. Today, solar panels are 40% to 50% more efficient.
With that in mind, it is reasonable to assume that solar panels have an approximate energy payback period of 1 to 2 years.
