Determine the difference in simple payback time (years rounded to the tenths decimal place) for solar systems for the case of no tax credits vs. ITC tax credits. Assume a 20-year lifetime and 235,000 Mwh/year production. ignore transmission losses and solar panel degradation over time. Assume no maintenance costs per year, an installed 2021 solar panel cost based on rated power capacity for a 6 kW system to be $11,797, a residential electricity price ($.1228/kWh) and a Renewable Energy credit (26%) based on total installation costs given by the 2021 Solar Investment tax credit (ITC).
