A solar cover has a variety of purposes all of which will help you save time and money. Solar covers work by using the sun's free energy to heat your pool during the day, and will help to keep your pool water warmer at night or on cloudy days by trapping the heat in. The more heat you trap with your solar cover, the less money you will need to spend to heat your pool. Your solar cover will keep your swimming pool cleaner by blocking out dirt and debris from entering the water. You will be able to save time and energy, as you will not have to clean you pool as often.When your solar cover is in place while your pool is not being used you reduce the amount of water that is evaporated from your pool by trapping it inside. By using a solar cover and reducing the amount of water that is evaporated from your pool, solar cover owners also show a reduction in the amount of water and chemicals they need to add to their pools
