Main highlights

Wide size and high capacity: the solar panel is available in eight sizes from 300 x 70 cm to 600 x 140 cm and covers a wide range of applications. The smallest version with 4.7 litres is suitable for pools up to approx. 12,000 litres, while the largest version with 18.4 litres is designed for pools up to 48,000 litres. This gradation allows for precise selection depending on the pool size and desired heat output.
MODULAR SYSTEM FOR INDIVIDUAL ENERGY The sophisticated module system allows flexible expansion of the heating output by connecting several collectors in series. Depending on the desired water temperature and pool volume, the system can be individually adjusted. This allows for needs-based scaling from small to large pools and ensures optimal use of the available solar energy.
Effective water heating: the KESSER solar panel uses solar energy to heat the pool water and allows a temperature increase of up to 6 °C – depending on sunlight, flow and pool size. The heat-absorbing surface absorbs radiation efficiently while the water absorbs heat and is returned to the circuit for even heating without additional energy costs.
Comprehensive accessories for safe installation. Included are end caps, stainless steel hose clamps, hose adapters and Teflon tape for a tight and reliable connection of all components. The high-quality fasteners ensure secure installation and stable operation even during prolonged use. This ensures long-lasting use and efficient heat transfer throughout the system.
Compatible and easy to use: thanks to the standardised connection diameter of 32 mm and 38 mm, the solar collector is compatible with standard pool hoses as well as standard filter and pump systems. Integration into existing water circuits is uncomplicated and without complex adjustments. This allows the pool heater to be quickly put into operation and used efficiently.

Main highlights

Versatile: you have the option to operate our solar panels with 32 mm or 38 mm hoses. You can also use these solar heaters to support the operation of a heat pump.
The connection: you need a connecting hose in the diameter of your preferred diameter for the connection. The flow rate should be rather low. Technically up to 10 m³/h are possible, but that would be too much for good results. PTFE sealing tape is recommended for sealing.
Strong heat: If you provide enough collector space for your pool, then you can heat up your pool very well. Note that the use of a solar film is necessary for good results.
Reusable: For medium and large pools, the use of several collectors is necessary. This can greatly increase the effect.
CORRECT DIMINATION: A solar panel should come with a maximum of 6,200 litres of water, so that they achieve reasonable results in practice. For example, a pool with 12,400 litres requires two solar panels as a minimum.
