What am I doing wrong here.
Our electric bill last month was $82 for 1145 KWH.
So we pay $13.96 per KWH.
So, If I got a system that would produce one KW (1000 Watts),
how long would it take to recoup the investment.
At an average cost of $4 per watt, the system would cost $4000.
The system can only generate full power about 6 hours per day average.
That means it generates 6 KWH per day.
So, 6 KWH x $13.96 per KWH = $83.76
$4000 divided by $83.76 = 47.76
So it would take 47.76 days to pay for itself.
Everything after that is free electricity.
This can't possible be right.
Can somebody please correct it.
