Please Note this is a general cost analysis, module selection, local permits, roof type etc. may factor in final project cost.
EXAMPLE 4410 Watt System consisting of 21 Sanyo 210 W modules.
This System (with south exposure & 40 degree tilt) will produce 6000 kWh year
Estimated to cost: $35,280.00 4410 x $8.00 per Watt installed
Pa. Sunshine Rebate - 7,717.50 4410 x $1.75 per Watt installed
W-1099 Fed tax on Rebate + 1,157.50 $7,717.50 x 15% tax bracket
Federal Income Tax Credit -10,584.00 $35,280.00 x 30%
Final cost after Grant & ITC $18,136.00
Figuring your return on investment.
PECO savings $ 900.00 6000 kWh year x .15 (PECO rate)
Sale of Energy Credits $ 1,680.00 6 x $280.00 (SREC price)
Annual savings/income $ 2,580.00
Take the NET COST of $18,136.00 divide by $2,580.00 = 7 year pay back
The system life is appx. 20 years, thats 13 more years @ $2,580.00 = $36,120.00 savings/income
