Today, the public institution “Krka National Park” presented a new project that contributes to the protection of nature and the environment: solar trees – SunInside.In cooperation with the Šibenik company Upgrade energy jdoo, three solar trees were installed at three locations: in the branch office of the Public Institution “NP Krka” in Skradin, on the meadow at Skradinski buk and at the entrance to Lozovac. “Our visitors, like all modern tourists, use mobile devices to take photos, inform, navigate the space and share content. It often happens that the batteries of the mobile phone are discharged, which is an obstacle to the complete ‘capture’ of the experience from the Park. By installing solar trees, we provide an additional service to visitors to the Park – we educate them about the possibilities of practical and efficient use of energy obtained from renewable sources. We are glad that the product is fully designed and manufactured in the Šibenik area, thus contributing to the development of domestic innovative technology, “Said the director of JU” NP Krka “mr. sc.
