En ISon21 nos proponen dos tipos de cubiertas solares: por un lado tejas solares de cristal, y por otro la cubierta solar térmica:
In ISon21 they propose two types of solar covers: first glass solar shingles, andother solar thermal cover:
Tejas solares de cristal: son un producto de la empresa sueca SolTech Energy, y no hacen uso de la tecnología solar activa como los paneles fotovoltaicos, sino que se sirven de la tecnología solar pasiva, que consiste básicamente en que el aire que circula por debajo de las tejas se calienta con el sol y es redirigido a un sistema de calefacción central. Lo mejor que tienen es que pueden instalarse en una cubierta tradicional y con métodos tradicionales y su duración es muy superior a la teja árabe de barro o a las de cemento. Son ideales para lugares fríos, ya que son capaces de derretir rápidamente la nieve y el hielo.
Solar Glass Tiles: they are a product of the Swedish Energy Soltech and not make use of active solar technology and solar panels, but that use passive solar technology, which essentially means that the air flowing below the tiles are heated by the sun and is redirected to a central heating system. The best we have is that they fit into a traditional roof with traditional methods and the duration is much higher than the Moorish tiles or clay cement. They are ideal for cold weather, since they are capable of rapidly melting snow and ice.
Thermal Solar Roof: the company has created Energy Alternatives Greenward Ridge Vent, which is a cover mode running at a large solar collector, with some advantages, such as installing pipes along the main liner ridge, wich besides be the hottest part is the one that receives natural ventilation. In functions as a boiler: hot water circulates, consumed or stored.
