Each unit is covered by an upper transparent sheet, provided with conducting means distributed over the sheet for conducting of electric current for heating of the sheet, The device is especially characterised in that the conducting means consists of a thin layer of conducting material such as a metal oxide distributed over the surface of the sheet, whereas at the edges of the sheet there are arranged conducting bars for the feed of electric voltage.

Description

Device at solar panel
The present invention relates to a device at solar panel for the production of electric current at solar lightning, comprising a number of solar cells with plane surface, assembled to preferably rectangular units, whereas each unit is covered by an upper transparent sheet, whereas this sheet is provided with conducting means distributed over the sheet for conducting of electric current for heating of the sheet.
Solar cells have become more important due to the rising energy costs and with rising concern about the climate, aiming at reducing of the discharge of carbon dioxide from combustion in order to stop the temperature rise in the atmosphere. The solar cells may be used, giving electrical energy even at relatively low sunshine. In the northern countries the usage is limited by snow and ice, preventing the solar beams to reach the active elements of the solar panels. In JP 8260638 A it has been suggested to cover the solar cells by a glass sheet provided with a filament in order to melt any snow and ice present. This construction is, however, relatively expensive, and there has been a need for a more efficient solution of the problem to remove snow and ice from the solar panels.
The object of the present invention is thus to achieve a device of the art mentioned introductorily, which is simple in construction and which admits the solar panels to produce electrical energy even at relatively low ambient temperatures with snow and ice present at the surface of the solar panels. According to the invention a device of the art mentioned introductorily is characterised in that the conducting means consists of a thin layer of conducting material such as a metal oxide distributed over the surface of the sheet, whereas at the edges of the sheet there are arranged conducting bars for the feed of electric voltage.
The sheet may be made from different transparent materials like plastic, but in one advantageous embodiment of the device the sheet is made from glass. It is advantageous to a connect a temperature gauge to the sheet, arranged to give a signal to a switch for coupling of electrical voltage when the temperature gauge measures a lowest temperature, determined beforehand. In this embodiment the device operates automatically during the cold part of the year.
If a switch clock is provided for coupling of an electric voltage to the device according to a desired day- or week program there is no need for any supervision at all.
The device is described in the following, reference being made to the enclosed figure, showing a schedule of the device.
In the figure a number of solar cells are commonly denoted 1. They are covered by a transparent sheet 2. A conducting means 3 is arranged in the form of a thin layer of conducting material such as a metal oxide distributed over the surface of the sheet. At the edges of the sheet there are arranged conducting bars 4 for the feed of electric voltage.
A temperature gauge 5 is connected to the sheet, arranged to give a signal to a switch 6 for coupling when the temperature gauge measures a lowest temperature, determined beforehand.
A switch clock 7 is provided for coupling of an electric voltage to the device via the wires 10 And 1 1 according to a desired day- or week program during the period of time when heating of the sheet may be needed.
