Flächenheizelement zur Erwärmung von Photovoltaikpaneelen
Electricity generation with more environmentally-friendly, a bid is the hour more exhaust-free[...] energy. Besides water power and wind power Is it Photovoltaic, which provides free of charge electrical energy. Photovoltaic uses the direct and the diffuse irradiation by the sun wherein The invention relates to a system of panel heater with automatic ice incrustationsnow and the detection of the forward-looking. [...] provides for the specific heat ( [...] ) by melting a During the day of the snow, at night, however, must be heated and the PV is-Panel alien to cold, just as during the day, when the [...] is so strong that the generated by the PV-panel same staff thawing not sufficient for a specific heat. [...] ( [...] ) which snugly and consistent with a on the rear side of the PV-panel Is glued, will ensure that an immediate snowfall fusion effect Is given at onset. The warmed up heating foil ( [...] ) the PV-panel so that on the power-generating surface has a temperature of + 2 °C is prepared. The required therefor is 80 W power, depending on the angle of the establishment or whatflat being placed in view of the need for thawing temperature In an arrangement with an angle of for example, 30 ° to the horizontal the problem of convection of the generated heat occurs here, what requires a higher connect load of the heating strip. It is therefore necessary to provide for thermal insulation ( [...] ) which prevents the temperature loss. Here an eminent problem occurs at full solar radiation and that is the PV ~ surface temperature reaches 120-140Q C soft. A temperature-resistant insulating material used for these temperatures which It will therefore resistant Is. Another problem is the power supply of the PV-panels, according to invention is solved the task thereby that each heating element has two connection lines for the feed and the second for the wherein a supply of the further-PV panels serves ground through. A line lead than feed pipeline carried out has a waterproof connector has a watertight plug coupling and the second lead wire, it will thus have a secure and lasting water as well as the rapid and rational mounting guaranteed forwarding ( [...] ). Supplying the heating foil takes place directly on the heating element by a waterproof T bonded-branch on which the connection lines are connected firmly and permanently. [...] invention is further the security of the job of the heat transfer and heat distribution through the heating element and the resistance of the material used. according to invention a 3-conductor 230 °C resistance braid and a thin heating cable consisting of 2-2.5 mm is only connected temperature-resistant insulation of PTFE on a 5 mm grid spacing glass cloth net with firmly. This mat is 2er aluminium foil pay with glued and embedded within a compact panel heater so 0.2 mm starch yield.
