Goodbye to the idea that solar panels “die” after 25 years. A new study says the warranty does not mark the end, and real-world performance can last for decades
A 30-year field study from Switzerland shows many solar panels still produce over 80% of their original output after three decades, with degradation closer to 0.25% per year. The findings challenge common financial assumptions and reshape how we think about mid-life solar assets.
Trump administration scraps multimillion-dollar solar projects in Puerto Rico as grid crumbles
Puerto Rico has shown that distributed solar and batteries can deliver real reliability at scale, supporting the grid and preventing blackouts after years of system failure. Now, federal cuts to rooftop solar and storage programs risk undermining one of the clearest real-world examples of how distributed energy protects households, especially the most vulnerable.
Study says solar, storage could slash spiking New York energy bills
A new Synapse Energy Economics study finds that expanding distributed solar paired with battery storage could save New Yorkers up to $1 billion per year by 2035. The analysis highlights how local solar and storage can cut bills, ease winter peak stress, and reduce reliance on natural gas as electrification accelerates.
