Installing solar panels on school rooftops has become a common way for districts to cut electricity costs while also serving as a visible teaching tool for students studying renewable energy. Many districts finance these installations through power purchase agreements, in which a third-party company owns and maintains the panels while the school simply buys the electricity generated at a discounted, fixed rate, avoiding large upfront costs. Panels generate the most electricity during summer months, which often coincides with reduced school usage during vacation, so some districts sell surplus power back to the grid during this period. Roof age and structural condition must be assessed beforehand, since aging roofs may require costly reinforcement or replacement before panels can be safely installed.
