Harol will be launching the first ever solar surface-mounted screen, a zip screen that can be installed with no demolition or electrical work. Simple for both the consumer and the installer. Servicing and inspection take an instant because the box is accessed via just two screws at the front. SC800-ZIP Solar is available in three box sizes (90, 110 and 150 cm) with a maximum area of up to 7.5 m2. The battery can be fitted either inside or outside the box.
