But up lots of Solar Panels...That should raise the Urban / Local Temp / Heat. !!
*** Yes, scientific studies indicate that widespread solar panel installations can, under certain conditions, contribute to a localized increase in urban heat, particularly during the day. This phenomenon, known as the "PV heat island effect," is primarily due to the lower albedo (reflectivity) of solar panels compared to traditional roofing materials, leading to increased absorption of solar radiation and subsequent heat release.
