The hybrid solar panel that meets the heating, domestic hot water and electricity needs of the home. The finned version of the SPRING 4 is specially dedicated to coupling with solar thermal heat pumps (glycoled-water/water), for 100% renewable energy homes.
⇒ Up to 90% savings on your overall energy bill: when the finned SPRING 4 is coupled to a glycoled-water/water heat pump.
⇒ 1.2 times more efficient than a traditional air/water heat pump
⇒ Aesthetic and solid rendering thanks to the black aluminum frame.
