CALCULATIONS

Energy Audit 13000 kWh/year Cost from grid $0.092/kWH

Since there are 8760 hours in a standard year Cost per year $1,196.00

Power Needed 1.5kW System Durability 20 years

Sunshine in CO 6hr Net profit $11,328

Power in this time 6kW Net yearly profit $630

Spec 600 sq.ft.

South facing on roof 520 sq. ft.

Mounting on roof allows us to expad that area

Cost of inverter+PV $3/W

Cost of Power 18,000.00State Subsidy (3,600.00)

Federal Subsidy (4,200.00)

Total Cost 10,200.00
