What is a solar cover and what does it do?

A solar cover, also known as a solar blanket or pool cover, is a large sheet of durable material designed to cover a swimming pool. It is typically made of UV-resistant vinyl or plastic with air bubbles trapped within its layers. The primary purpose of a solar cover is to harness the power of the sun to heat the pool water. The cover acts as a barrier, preventing heat loss by reducing evaporation and overnight cooling. It also helps to retain the heat generated by a pool heater. Additionally, a solar cover minimizes debris, leaves, and insects from entering the pool, reducing maintenance time. By using a solar cover, pool owners can increase water temperature, extend the swimming season, and save energy and chemical costs.
