Description

The utility model relates to the field of solar energy, namely to methods for preventing pollution of solar modules, and can be used to protect solar modules from surface contamination by dust.

Known methods for cleaning solar modules (Vissarionov V. I. Solar energy: a textbook for universities / V. I. Vissarionov, G. V. Deryugina, V. A. Kuznetsova, N. K. Malinin. Moscow: MPEI Publishing House, 2008 . - 317 p.), the main disadvantage of which is that they clean the already contaminated modules, and do not prevent pollution in general, thereby reducing their energy characteristics, increasing the degradation of the modules and reducing their service life.

This disadvantage is partially eliminated in a transparent self-cleaning dust screen (patent US No. 2004055632 A1 dated March 25, 2004, "Transparent self-cleaning dust screen", IPC A47L13 / 40; F24J2 / 46; H01L31 / 00; H01L31 / 0216; H01L31 / 042; H01L3 1/ 048) containing a panel of transparent non-conductive (dielectric) material with built-in parallel electrodes.

The disadvantage of this design is that it is not suitable for large ground solar power plants (SPP) and systems, since it requires expensive ITO electrodes and a three-dimensional structure at the end of the electrode to accommodate the polyphase circuit.

The technical result of the proposed utility model is to prevent pollution of solar modules in order to preserve their energy characteristics, reduce the degradation of modules and increase their service life.

The specified technical result is achieved due to the fact that in a device for preventing pollution and degradation of solar modules, containing parallel rows of potential and grounded collecting electrodes, made with the possibility of supplying high voltage (up to 10 kV) to them from a high voltage source, according to the utility model collecting electrodes are fixed on a frame made in proportion to the area of the solar module housing with the possibility of its dismantling for cleaning the collecting electrodes and fixed on the solar module housing.

Due to the fact that high voltage (up to 10 kV) is applied to potential collecting electrodes installed in a frame above the surface of the solar module from a high voltage source (HPV), an electric field is created, which allows bipolar charged dust particles to be attracted to the collecting electrodes, and not settle on the surface of the solar module, preventing dusting of the surface of the solar cell, leading to a decrease in the efficiency of the solar module and its rapid degradation.

The utility model is illustrated by drawings, where

in fig. 1 shows a general view of a device for preventing surface contamination of solar modules with vertically arranged collecting electrodes,

in fig. 2 is a general view of the device for preventing surface contamination of solar modules with horizontally arranged collecting electrodes.

The device for preventing pollution and degradation of solar modules (Fig. 1 and Fig. 2) contains a frame 1, on which there are parallel rows of potential and grounded collecting electrodes 2. Frame 1 is fixed on the body of the solar module 3 (stably, but not rigidly), high voltage (up to 10 kV) is supplied to potential collecting electrodes 2 from a high voltage source 4.

The proposed device for preventing pollution and degradation of solar modules works as follows.

A high voltage (up to 10 kV) is supplied to the frame 1 (Fig. 1 and Fig. 2) with parallel rows of potential and grounded collecting electrodes 2 from a high voltage source 4 with the formation of an electric field. Dust particles 5, having an electric bipolar positive or negative charge, approaching the surface of the solar module 3, fall into the electric field of the interelectrode gap and, under the action of the electric forces of this field, settle on the collecting electrodes 2 of the frame 1 of the sign opposite to its charge. After complete contamination of the collecting electrodes 2, the frame 1 is dismantled and the collecting electrodes 2 are cleaned from the deposited dust, after which the frame 1 with the collecting electrodes 2 is again installed on the solar module 3.

Compared with the prototype, the claimed device fully solves the problem of pollution of solar modules.

The proposed utility model can be applied to any solar modules operating in an air environment with a high content of large dust particles and fine dust particles.
