Sun2Solar Blue 20×50 — 1200 Series Solar Cover
The Sun2Solar 1200 Series is a heat-retaining solar blanket designed for rectangular pools measuring 20 feet by 50 feet. This cover uses solar energy to raise water temperature and helps maintain warmth after sunset. It also reduces water loss due to evaporation by a significant margin, supporting a more efficient pool chemical and water use profile. The model includes six heavy-duty grommets for secure installation, useful in windy environments and when connecting multiple sheets for full coverage.
Sun2Solar Blue 20×50 — 1600 Series Solar Cover
The 1600 Series from Sun2Solar offers robust heat retention and efficient solar heating for large 20×50 pools. Like other solar blankets in this line, it helps raise water temperatures and maintain warmth throughout the night, reducing the need for extra chemical treatments by limiting evaporation. The included six heavy-duty grommets aid in stable anchoring to prevent shifting during storms or heavy winds, ensuring consistent coverage.
Patio 20×45 Inground Pool Cover — Safety and Debris Blocking
Although sized at 20×45 feet, this Patio Store cover is a strong option for smaller 20×50 installations or for pools with safety and winter considerations. Constructed with heavy-duty polyethylene and a wire rope hem, it features a tension distribution system to reduce sag and maintain a tight fit. The mesh design helps shed leaves and debris while allowing water to drain, reducing standing water on the cover. It’s UV-resistant and designed for long outdoor use across multiple seasons.
Sun2Solar Clear 20×50 — 1600 Series Solar Cover
The Sun2Solar Clear 1600 Series combines transparent design with heat-retaining properties to maximize solar gain while maintaining visibility. This option is designed to raise water temperature by up to 15 degrees and to minimize evaporation by up to 95%, helping with water conservation and chemical efficiency. The covered pool remains warmer after sunset, supporting a more comfortable swimming experience with less energy input for heating.
Sun2Solar Blue 20×50 — 800 Series Solar Cover
The 800 Series from Sun2Solar emphasizes bubble heating blankets designed for effective solar gain on rectangular pools. This option maintains warmth overnight by trapping heat and reducing evaporation, with the same core benefits of solar-assisted heating and water conservation. It’s a practical selection for users seeking a reliable cover with straightforward setup and durable construction.
Buying Guide: Key Purchase Considerations
- Pool dimensions and fit: Confirm that the cover matches a 20×50 footprint or offers an exact or compatible size for your pool edges and shape. Mismatched covers can fail to seal and reduce evaporation benefits.
- Heat retention vs. transparency: Solid blue and dark surfaces maximize heat retention, while clear or translucent covers enable more solar gain during the day. Some users prefer clear options for greater sun exposure and visibility.
- Material durability: Look for heavy-duty polyethylene or reinforced laminates with UV resistance. A cover should withstand wind, rain, and sun exposure over multiple seasons.
- Grommets and anchoring: Bundled grommets or tie-down systems improve stability in windy conditions. Ensure your pool edge and deck design support secure fastening.
- Evaporation reduction: A primary benefit of these solar covers is evaporation control. A higher reduction percentage correlates with lower chemical usage and water top-offs.
- Safety considerations: If a safety cover is required, evaluate specialized options designed to support weight and provide secure anchoring, rather than standard solar blankets.
- Maintenance and cleaning: Mesh-blocking or debris-shedding features help keep the pool clean and reduce vacuuming time. Some covers allow leaves and debris to wash through with rainwater.
- Installation and storage: Consider whether the cover is easy to deploy and remove, and whether you need a reel or lift system for convenient handling during off-season storage.
When selecting among these options, evaluate your priorities—whether heat gain, evaporation reduction, safety needs, or budget—and how a given model’s features align with the size and usage patterns of your 20×50 pool. The right cover can extend the swimming season, reduce energy costs, and keep your pool cleaner with less maintenance.
