Concerns over the longevity and efficiency of solar panels took center stage at the Tompkins County Facilities and Infrastructure Committee meeting on September 18, 2025. Committee members discussed the challenges posed by aging roofs and the implications for solar energy generation, highlighting a shift in strategy towards ground-mounted solar solutions.
The discussion began with committee member Aurel raising questions about the financial impact of expiring leases and the maintenance of solar panels installed on roofs. Aurel expressed concerns about the difficulties in monitoring energy production due to outdated technology and the added costs associated with roof replacements. "When we have leaks, they're hard to find," Aurel noted, emphasizing the complications of maintaining solar panels on aging roofs.
Jerry, another committee member, echoed these sentiments, pointing out that the expected lifespan of solar panels has increased significantly. "Originally, we thought solar arrays would last around 20 years, but now they can last 30 to 40 years," he explained. This extended lifespan raises concerns about the need for roof replacements, which would require removing and reinstalling solar panels, leading to additional expenses.
The committee also discussed the efficiency of new windows in county buildings, with members noting that while modern windows are more energy-efficient, the overall cost-effectiveness remains a challenge. "The loss here in this building is high," one member remarked, indicating that while new windows could reduce energy bills, they may not pay for themselves in the long run.
As the meeting concluded, the committee recognized the need to reconsider building designs, particularly regarding roof types. The discussion highlighted the potential benefits of sloped roofs over flat roofs, especially in climates prone to heavy snowfall and water accumulation. The committee is set to explore these options further as they plan for future infrastructure projects, including the new Center of Government building.
The meeting underscored the importance of adapting to advancements in solar technology and energy efficiency, as Tompkins County navigates the complexities of maintaining its facilities while striving for sustainability.
