Yes it does. The devil's in the details. Doesn't cover labor, or future value of money (inflation on currency). Rural China will likely realize a 100% ROI in 7 years. Best of luck.

New generation of Solar panels use 2X Silver & roughly have 2X electric output per sq ft. Like all panels, they roughly loose 35% output every 15 years. Beware of accountant's showing constant outputs for 30 years to pay off 30 yr loans.
