Save money year-round with thermal solar system not only for generating electricity, but also for hot water or space heating, sunlight on the roof can be used. Dach.de experts tell you how. An effective technique, can be used to make the free energy of the Sun for the budget is the solar thermal energy: Sunlight on the roof will be through a solar collector transformed into heat, which is routed through a carrier liquid to a separate store and there the water heated. According to experts of the online portal dach.de can a Solarthermie-system on the roof in the summer months the complete energy consumption for hot water of a household cover: meet for a four person household consumption already five square meters of collector area. Potential savings and other financial incentives even to heating support, the system is ideally suited. The heating and hot water cause almost 90 per cent of the domestic energy needs. Here, the high saving potential of environmental technology is clearly visible.
Additional Special funding programs provide financial incentives: so the base funding during the initial installation of equipment for the preparation of hot water on the roof is 60 Euro per commenced square metre, but at least 410 euros per plant up to 40 m gross collector area. Granted to an extended use even 105 euros per square meter. The collectors produce enough heat even in winter or on cloudy for the domestic needs: from April/May to September the system provides sufficient energy for domestic hot water heating even on cloudy days. According to the dach.de experts the actual boiler can be, turned off thus fully what at the same time extended his life by a quarter. The consumption still to 60 percent with the free energy can be covered in the winter. Even models offer almost invisible technique known manufacturer, can be easily integrated into the existing structure of the roof. At the roof level, the solar collectors cause no visual impact of the Roof more, that could harm the image of the House.
The proper installation and in particular the proper roof construction include the careful planning: A southern orientation with an inclination between 25 and 60 degrees is recommended. Dach.de experts consider a slope of 30 degrees as optimal. The non-roof elements of the solar system should be included in the considerations: A large store offers, for example, reserves, if multiple people want to shower in a row. But at the same time the heat losses increase with the size. In this context, well insulated cables for the transfer fluid must be observed to keep efficiency high.
