It’s not clear that the panels are $18000 apiece, but even if the whole installation was $18k, it would still be 44.5 years before the system actually paid for itself.
These panels are on the ground, but a lot of panels are on roofs. What does this do to your roof, as far as wear and tear?
It hardly seems cost effective.
Sopater,
you made a mistake in the math; the 12 modules cost 18000.00 installed:
18000-3600=14400 Focus on Energy Rebate
14400 -30% = 10,080 Federal Tax Credit
10080/400=25.2 Years Simple Payback
The cost of energy is not going to be .11 cents per kWh in 25 years, therefore
At 7% average increase in energy costs payback will most likely occur in 15 Years. The system will be warranted for 25 and likely last for 35 years.
