Extracted text: The average annual electricity consumption for a single-family house is 5000 kWh with the cost per hour extracted from their bill to be $0.17 / h. you suggested a PV system that will reduce the consumption to 25% of the original consumption. The system will have initial cost after all incentives of $9,000 with zero salvage value at the end of the service life. Using 25 years analysis period and 3% interest rate, find the following for the 75% saving resulted from the new system. Use the attached excel sheet for your calculations. 1. Present worth 2. Simple payback 3. Discounted payback using the 3% rate 4. Internal rate of return
