Solar covers are typically made of a material that can trap and retain heat, while black covers may absorb heat but not necessarily transfer it effectively to the water. Additionally, solar covers can help reduce evaporation and keep debris out of the pool, which can also contribute to maintaining a warmer temperature. **
