First Job. Salary: $50,000 or less

You're fresh out of college and managed to land a gig with your professor's cousin's daughter's boyfriend's boss's company. You consider yourself lucky, even if it means you're just handing tools to people and making sure nothing falls off the roof and onto your face.

Moving Up the Ranks. Salary: $60,000

Your supervisor actually trusted you to climb the ladder today, and last week you were told that, with a bit more experience, you could start installation training. You know it's only a matter of time before you start designing solar panel structures.

Up There! On the Rooftops! Salary: $70,000 

You're up on the rooftops feeling like Batman as you dodge rotten shingles and save arctic sea life one panel at a time. You're doing pretty darn well paycheck-wise, even though your grandma is still mad at you for being single. But hey—if Superman can handle flak from the entire world in Batman vs Superman, then you can deal with unhappy grandmas.

Senior Architect Designer Person. Salary: $80,000

You are juggling entire projects and handing fancy-looking blueprints (that you drew up) to your coworkers left and right. You're in charge of designing solar panel setups on skyscrapers and factories, not just homes and swimming pools. Go you.

Practically Reversing Nuclear Fallout. Salary: $100,000+

You're beyond installing solar panels. Now, you create them. You're on the verge of inventing the next new solar energy unit, you own your own solar power plant, and penguins are writing you personal letters of thanks for saving their ice caps.
