- Solar Power Efficiency: Say goodbye to expensive bills! Our solar panels use a high-efficiency tube grid design to absorb maximum sunlight, heating up to 3,408 gallons of water and raising temperatures by 10.8°F. Enjoy a cozy pool without electric or gas expenses!
- Ultra-Durable All-Weather PE Material: Built to last, these panels withstand extreme temperatures from -20°C (-1°F) to 90°C (194°F), resisting sun damage, rain, and rooftop wear. The heat-absorbing black PE material ensures optimal solar conversion for long-lasting performance.
- Hassle-Free Setup: No plumbing expertise needed! With included hose clamps, adapters, and connectors, installation is quick and hassle-free. Just attach to your pool pump, unwind the panels, and let the sun do the rest—more swimming, less tinkering!
- Portable & Versatile for Any Pool: Roll them up, move them anywhere! These lightweight panels work on roofs, frames, or the ground, fitting both above-ground and in-ground pools. (Water pump is not included which power rate is not less than 0.75HP and pressure does not exceed 1.5bal(21 PSI))
- Smart Sizing for Every Pool: For 12’-18’ round or 12’x24’ rectangular pools, one 16.5FT/20FT heater suffices (or two 10FT units). Larger pools (21’-24’ round or 16’x30’) need two 16.5FT/20FT heaters (or four 10FT). Smaller pools? Adjust accordingly—easy! Connect more heaters together for better results!
