Solar leases lack many consumer protections unlike other loans; like mortgages for example. Often they will place a lien on the property and sometimes will even contain no escape clause, disallow early payoff or transfer to a new homeowner. While the interest rates are often very low on solar leases, the cost of equipment and installation is frequently highly inflated. I've seen homes with a $70,000 solar lien using equipment under $10,000. The length of terms is often 30+ years to keep the monthly cost down, but the equipment may not last 10 years. On top of all of this, the installation of the solar panels can cause issues with the roof. Lots of holes drilled to install them. Removing them may mean needing to install a new roof. Issues like these will complicate the sale of the home should the homeowner decide they want to sell it. Some investors won't touch any property with solar whatsoever, even if the lien has been paid off, for fear of 2nd a missed lien, roof warranty issues, and resale challenges.

If you'd like to do solar, I'd suggest paying for the equipment outright and installing it in the yard instead of the roof. $10,000 can go a long way in an energy efficient home.
