What about this investment in a solar hot water system?

It is ironic that you, if you are an individual using LP gas or electricity to heat water, will pay for a solar hot water system over the next 4 to 8 years whether you get one or not!! You can invest today in a solar hot water heating system and have monthly savings and increased equity value in your home, or you can pay the local utility company every month. Your solar system savings will offset your payments, so you will actually own your solar water heating system at the end of five years. Remember that all solar savings are in non-taxable income, so a dollar saved on your water heating expense is equivalent to $1.30 or more of your taxable income.
