Energy-efficient, cool roofing systems can significantly
reduce roof temperatures during the summer, which does in fact improve the
performance of the photovoltaic system.
Another benefit of a cool roof is that it can significantly enhance the
performance of solar panels by lowering a building’s interior temperature, thus
reducing the power load necessary for air conditioning during hot summer days.
This has many benefits including cutting energy costs by keeping attics and
ducts cooler, improving occupant comfort, cutting maintenance costs, increasing
the life cycle of the roof, and reducing urban heat islands along with
associated smog.
