The solar pool cover has one main purpose; to keep your pool water warmer so you can swim longer. They do this by creating an isolation barrier between the surface of your pond's water and the surrounding air. The solar cover is often used in conjunction with pool heaters.
Apart from producing heat during the day, the sun cover helps maintain heat from the sun and the heat generated by pool heating during cold curfews. By preserving the heat generated, the solar cover saves your money. You don't need to heat the water again. Automatic pool covers eliminate the hassle and effort of covering and uncovering your inground swimming pool.

Solar covers are like bubble wrap for your pool. They consist of two vinyl sheets separated by a bubble layer that creates an airbag between the atmosphere and your pool. This "dead air" layer serves as insulation to keep heat, chemicals, and water in your pond. So solar covers will prevent evaporation of water and chemicals while maintaining heat.
Solar covers are very effective when used with conventional pool heaters or solar because at night they will withstand heat absorbed or generated during the day, thereby reducing fuel costs for traditional pool heaters or heat pumps.
Solar covers are usually used with a cover reel that makes putting the cover and removing it easier. This also protects the cover when the pool is being used.
