The answer is: “Absolutely!!” The more important question is: “How much?” Then the answer is: “It depends on who you ask”. You see, up until recently, the only reference was an outdated real estate report that was over 10 years old and an older study by the U.S. Department of Energy. A more recent NREL (National Renewable Energy Laboratory) report, in what has been deemed the most detailed study to date, determined that buildings with solar panels sold on average 20% faster and commanded a 17% premium price than their non-solar equivalents.
The true barometer is that if someone seeking a home or business to buy compares 2 nearly identical buildings in the same area, they most certainly will go with the energy efficient solar-installed one. It will provide them a return for years to come.
