Adelphi University covers sports facility with new roof and solar project

Adelphi University in Long Island, New York, just switched on a new 295-kilowatt rooftop solar system on its Center for Recreation and Sports. The project came together after the gym roof failed early and needed replacing anyway. Rather than just fix the roof, the school paired the repair with a 546-panel solar installation, getting more value out of the work it had to do regardless. The system will offset part of the building's energy use.

This isn't Adelphi's first sustainability project. The campus has run a geothermal heating and cooling system since 2003, added a smaller 50-kilowatt solar array on its library in 2011, and installed a 2-megawatt cogeneration plant (a system that generates electricity and useful heat together) in 2016. The new rooftop system is owned and operated by Greenskies Clean Energy under a power purchase agreement, meaning the university buys the power the system produces rather than owning the equipment itself.

For a homeowner, the main takeaway here is less about the specific technology and more about the strategy: when a roof needs replacing anyway, it can make sense to add solar at the same time rather than treating the two projects separately. Combining roof work with a solar installation can mean one round of labor and scaffolding instead of two, and it avoids installing solar on a roof that may need replacing again soon after. If you're facing a roof replacement on your own home, it's worth asking whether solar makes sense to add while the roof is already open, and checking what incentives or financing options your state offers for pairing the two.
