Climate change will drive the value of rooftop solar

Release Time:

2024-06-20

Researchers at the University of Michigan found that under mild climate change, the value of rooftop solar will increase by 5 to 15 percent by mid-century in a range of U.S. cities, and up to 20 percent by the end of the century.

Researchers at the University of Michigan have found that climate change will increase the future value of solar panels on residential rooftops across the United States by 20 percent by the end of the century.

In a recent publication in the journal Nature Climate Change,"Climate change will affect the value and optimal adoption of residential rooftop solar energyIn this paper, researchers quantify the impact of climate change on rooftop PV value and optimal capacity,

According to the study's lead author, Mai Shi:

"The value here refers to economic value-how much electricity is saved when a home installs a rooftop solar system." "Our analysis captures how climate change will affect household electricity demand by increasing cooling demand and household rooftop photovoltaics."

The researchers say rooftop solar value will increase by 5 to 15 percent in a wide range of U.S. cities by mid-century under mild climate change, and then by 20 percent by the end of the century. Greater value added was analyzed in homes with greater cooling intensity and urban radiation and higher retail electricity prices.

Of the 17 cities, Miami and Orlando are expected to see the strongest growth in solar value.InIn these cities, climate change is expected to increase solar radiation, which in turn will favor more rooftop PV, while an increase in air temperature will lead to more household electricity demand.

The researchers also concluded that as the value of rooftop photovoltaics increases, the economically optimal capacity of the home also rises. They predict that under mild climate scenarios, power generation capacity will increase by 5 to 25 percent by the end of the century. The researchers say the results have implications for current and future rooftop PV customers.

"Considering that the average life of a rooftop solar installation is 25 years, the system built today will almost experience the weather of 2050. Therefore, it is important for households to consider the future value when building solar energy," Shi said. "If families do this, our findings suggest that they will see greater value in solar energy and may decide to build more."
