Example # 1

Modular photovoltaic facade thermal insulation system, according to fig. 1, consists of three mutually detachable facade panels 7. The facade panel f is attached to the building facade 6. The facade panel 1, according to FIG. 2, is formed by a full-frame frame 2, which is made of plastic. In the inner part of the all-frame frame 2 is a frame reinforcement 21 which is made of hot-dip galvanized metal. A drain groove 22 is provided in the entire peripheral frame 2 for the condensate drain. One side of the photovoltaic cell 3 with a washer 31 is detachably attached to the full-frame frame 2. On the other side of the photovoltaic cell 3 is inserted a thermal insulation insert 4, which is glass wool.

Industrial usability

The technical solution can be used to generate electricity from solar energy incident on a photovoltaic cell, which is connected to the power system. Another use is to heat water and to heat the façade walls if the façades are equipped with a built-in pipe system, thus reducing the energy consumption of buildings. The technical solution can be used as an interesting aesthetic exterior complement of the building facade, as well as as a thermal insulation element minimizing the heat loss of the building and at the same time producing electricity.
