Electric shutter made of insulated aluminium, ideal to prevent water from overheating, protect against hail, and cover the system when not used for long periods.

Thanks to a special drive system , the shutter can operate at any angle, both on the roof and on brackets for flat surfaces, and in any direction, from the bottom up and vice versa or sideways.

Lets you adjust water temperature simply by increasing or decreasing the exposed surface area of the solar panel.

On large surfaces, multiple panels can be installed next to each other.
