Climate change is set to impact the future value of residential rooftop solar panels across the United States significantly, with a potential increase of up to 19% by the end of the century. This information comes from a recent study led by the University of Michigan, which looks at how the Value of Solar (VOS) will be affected by changing weather patterns.
The study defines the value of solar as the financial benefits at the household level, which includes savings on electricity bills and revenue generated from selling excess electricity back to the grid, minus the initial setup costs. One of the key drivers of the expected financial gain is the increased demand for residential air-conditioning as temperatures rise due to climate change.
Impact of Climate Change on Solar Panel Performance
Another critical factor influencing the future value of rooftop solar panels is their performance in response to changing weather patterns. Climate change is expected to affect the efficiency of solar panels differently in various locations across the U.S. For instance, cities like Miami could see a significant increase in the value of solar panels, while cities like Minneapolis might experience a decrease in financial benefits.
Under the moderate climate scenario considered in the study, demand for residential cooling is projected to rise in all 17 cities analyzed. By mid-century, cooling demand is expected to increase by an average of 35%, and by the end of the century, it could rise by 64%. This increased demand means that a higher proportion of solar-generated electricity will be utilized for powering home cooling systems rather than being sent back to the grid.
While the study predicts future financial gains mainly for households that can afford to install rooftop solar panels, there are initiatives in place to make the technology more accessible to lower-income individuals. Various programs aim to defray the costs associated with solar installation, and governments can also install rooftop solar on public buildings to provide benefits to tenants. Additionally, community solar programs can help entire communities reap the rewards of solar energy.
Overall, the potential increase in the future value of residential rooftop solar panels highlights the importance of considering the impacts of climate change when making decisions about solar installation. With the right policies and programs in place, more households can benefit from this renewable energy source as we work towards a more sustainable future.
