Lets Assume the homeowner adds the option of a $4,300.00 solar hot water system to a new home.
A conventional hot water tank would cost between $300.00 or $600.00 per installation for new construction.
This means that a minimum of $4,000.00 is the upgrade option for solar water heating systems with an 80-gallon solar tank with an electric element for cloudy days.
The federal tax rebate or credit off taxes owed is 30% of the $4,300.00 solar option or $1,290.00. Assume a 3% down payment of $120.00 and interest rate of 6% over a thirty-year period.
The spreadsheet below in the 35% income tax bracket for the itemized deduction, the utility savings are based on current natural gas prices for 4 people, or electricity or LP gas for 3 people with a 2% increase per year. Below is the first five-year spreadsheet of a thirty year mortgage.
