I have a micro fit solar panel installation. I have taken out a loan for it. To save on interest, I want to refinance my mortgage and increase the amount by the size of the loan. Can I claim the mortgage interest on the amount I increase the mortgage? If so, how long do I have to pay it off....in other words, if I have a 25 year amortized mortgage, can I claim the interest for the full 25 years?
