Hi,
How much time does it take on average to pay off one solar panel and how much time does it take before the one solar panel wears out?
Like this:
It takes approximately one year of average electricity production at current prices for electricity to offset the price of one solar panel.
One solar panel will continue producing about the same amount of electricity for 25 years total.
Therefore:
1/24 is the cost/benefit ratio.
How about filling in the blank?
One solar panel will produce enough electricity in BLANK A months, at current prices for electricity, to pay for on solar panel priced at currency prices and each solar panel will continue to generate at that rate or no less than 90 percent of that rate for BLANK B months total.
If Blank A is 12 and Blank B is 300 then he cost/benefit ratio is 1/24 as 12 – 300 = 288 (benefit) and 12 is the cost or 12/288 = 1/24
Please fill in the two blanks asked.
Blank A = pay off time interval in months (average for U.S.A or California)
Blank B = time interval between new and when the unit wears out (less than 90 percent production rate) assuming full production on average (no unusual or planned down time).
