The document provides 4 legitimate excuses for not installing solar panels on a home: 1) not owning a home, 2) a home receiving almost no sun, 3) wanting to wait until replacing the roof, and 4) planning to sell the home soon. However, it notes that with Power Purchase Agreements, solar panels can be installed for free, so there are no longer any excuses to not go solar and start saving money and helping the environment.
