The Sun2Solar Blue 18 ft Round Pool Solar Cover is designed to help heat and protect both above-ground and inground pools using the sun’s natural energy. Made from resin material, it’s lightweight and easy to handle, which makes installation and removal straightforward. Its round shape fits an 18-foot pool, and the solid blue color helps absorb sunlight effectively.

The cover features bubble design technology that traps heat, raising water temperature by up to 15 degrees and keeping warmth overnight.

Additionally, it acts as a barrier against leaves and debris, cutting down on cleaning time. The cover is UV resistant, which adds to its durability under sun exposure. One limitation is that the product requires hand washing for care, which might be less convenient.

This solar cover is a strong option for pool owners seeking an easy-to-use, effective way to maintain warmer water and reduce maintenance.

The Sun2Solar Blue 16 ft x 32 ft Rectangle Solar Cover is a well-regarded option for those looking to retain heat in their swimming pools and reduce water evaporation. Made from durable polyethylene (PE), the cover is designed to trap heat effectively, raising the pool water temperature by up to 15 degrees and retaining warmth overnight. This is especially beneficial for extending the swimming season or enjoying warmer water without relying heavily on traditional heating methods.

Another significant advantage is its ability to prevent up to 95% of water evaporation, which not only conserves water but also reduces the need for chemical additives and pool maintenance time. The cover also helps keep leaves and debris out of the pool, ensuring it stays cleaner for longer periods between cleanings.

Measuring 16 feet by 32 feet, this rectangular cover is suitable for both inground and above ground pools of similar dimensions. The bubble design on the cover aids in heat retention and makes it lightweight enough for easy installation and removal. The blue color may not suit everyone's aesthetic preferences, but it is effective in absorbing and retaining heat. While some users have mentioned difficulty in handling and storage due to its size and weight, which is 26 pounds, its ability to float seamlessly and the additional overlap for a snug fit around pool edges and protrusions add to its ease of use.

The Sun2Solar Blue 18 ft Round Pool Solar Cover is designed to harness solar energy to heat your pool, making it suitable for both inground and above-ground pools. Made from resin, this cover is durable and lightweight, weighing only 4.24 pounds, which makes it easy to install and remove. The cover is round in shape and has an 18-foot diameter, ensuring it fits a variety of pool sizes.

Its blue color is aesthetically pleasing and helps with heat retention, raising the pool temperature by up to 15 degrees.

Additionally, it stops debris from entering the pool, reducing maintenance efforts.

However, the cover's lightweight nature, while making it easy to handle, might not offer the same level of durability and thermal insulation as heavier options. Users should also consider that while installation is straightforward, ensuring the cover fits perfectly around protrusions might take some time and adjustment. The hand wash-only care instructions could be seen as a minor inconvenience for some users. This product demonstrates a solid performance in maintaining pool temperature and cleanliness, making it a good choice for pool owners looking to reduce maintenance and heating costs.
