How To Choose The Right Solar Pool Covers?

  2. Color: Solar covers in dark colors can retain more heat and resist the sun’s effect on swimming pool chemicals.
  3. Shape and size of the pool: It is easy to find a solar cover for all shapes of pools, including rectangle, square, or round. If your swimming pool is large, you may have to consider the solar cover’s size and trim it according to the pool shape.

Solar covers/blankets help keep the swimming pool water warm and free of debris. They also protect the pool from wind, sun, or other weather conditions. If you have an in-ground pool, a solar cover is a must-have. There are various colors, sizes, and shapes on the market, and there are different installation and heat retention mechanisms.
