For Illinois in general…
50,000 square foot roof top = $1 million in savings over 25 years
100,000 square foot roof = $2 million in savings over 25 years
1.333 = production factor in Illinois (if at 180 degree tilt)
1.333 x 700 kw = annual kWh (kilowatt-hour) produce in year = 933
A kilowatt hour is when you add in your supply delivery, taxes, conservatively worth $0.08 = 1 kWh
Supply rate on average = 5.5
Take $0.08 x 933 (annual kwH produced in a year)
= ~$70,000/year in savings
Which = $6,000/month in electricity savings
Or ~$2 million in savings over 25 year warrantied life.
