Technical field
The utility model is related to photovoltaic plant technical field, and in particular to a kind of photovoltaic module cleannes sensing device.
Background technology
Photovoltaic generation is at home and abroad quickly grown in recent years as a kind of clean energy resource.However, the dust covering in air
The influence changed to photovoltaic battery panel energy is very big, becomes the difficulties of restriction photovoltaic generation.The U.S. " opportunity " number fire
Star detector just once faced this problem in task process is performed, in 2004-2010 6 years, because floating dust covers
Lid, its power attenuation 1/3.Equally, no matter roof photovoltaic power station or ground photovoltaic plant, all suffer from the feelings of component dust stratification
Condition, dust is to influence one of key factor of built photovoltaic power station power generation amount.
Influence of the dust to photovoltaic module mainly includes：
1st, the dust of surface of photovoltaic cell panel can block irradiation of the sunray to component, reduce and project photovoltaic cell
The solar radiation quantity on surface, so that photovoltaic module generated energy declines；
2nd, when there is dust on photovoltaic module surface, permanent sunlight irradiation makes assembly surface by shield portions heating much larger than not
Be blocked part, and the blackening burnt out occurs when temperature is too high --- hot spot.And hot spot effect is influence photovoltaic module output work
The key factor of rate and service life, can cause photovoltaic cell partial burnt-out formation blackening, solder joint fusing and encapsulating material aging
Etc. permanent damage, in some instances it may even be possible to cause potential safety hazard；
3rd, photovoltaic cell lid surface is mostly glass material, and the main component of glass is silica and lime stone etc.,
When the acid or alkaline dust of moistening is attached to glass cover plate surfaces, glass cover-plate component substances can react with acid or alkali.With
Time growth of the glass in acid or alkaline environment, glass surface will be slowly etched, so as to form hole hole on surface
Hollow phenomenon, causes light in lid surface formation diffusing reflection, propagation uniformity in glass is destroyed.
In order to overcome dust to cover the influence to photovoltaic module generated energy, it is necessary to design a kind of photovoltaic module cleannes and pass
Induction device, to gather the specific data that dust covering influences on photovoltaic module generated energy.
Utility model content
The technical problem that the utility model is solved is to provide a kind of gas net formula photovoltaic module cleannes sensing device, to examine
Photovoltaic module is surveyed because of power attenuation degree caused by dust covering, data foundation is provided for correlative study.
In order to solve the above problems, the utility model employs following technical scheme：
A kind of net formula photovoltaic module cleannes sensing device of gas, including contrast component one and contrast component two, the contrast
Component one is identical with the contrast mounting inclination angle of component two and azimuth, in addition to cleaning unit, data acquisition unit and power supply；Institute
Cylinder of the cleaning unit including air pump and located at the top of contrast component one is stated, the air pump connects cylinder, institute by tracheae
State cylinder and be provided with the air exhaust slot for being opened on contrast component one direction；The data acquisition unit connects contrast component one respectively
With contrast component two, the power for gathering the output of two block assemblies in real time；The power supply is is electrically connected contrast component one, right
Than the battery of component two, air pump and data acquisition unit, the battery is used to store the electric energy that two block assemblies are produced, and is gas
Pump and data acquisition unit are powered.
It is preferred that, the contrast component one and contrast component two have larger length-width ratio, and the air exhaust slot is along contrast groups
The long side direction of part one is set.
Further, in addition to display unit, the display unit connects data acquisition unit, for display data collection
The data of unit collection.
Further, in addition to data communication unit, the data communication unit connects data acquisition unit, for it is outer
Portion's equipment communication.
The net formula photovoltaic module cleannes sensing device of gas of the present utility model, it contrasts component one due to there is air exhaust slot always
Wind action is blown out, dust is not fallen on component, so that contrast component one keeps cleaning；Second and light and contrast component
The cleannes that other components of overhead utility are consistent.As soon as by comparing the power output of contrast component and contrast component two,
It is known that photovoltaic plant causes the degree of power drop because of unit clean degree problem, so as to be carried for photovoltaic plant cleaning plan
Foundation for reference.In order to ensure the effect of wind, component is set from the larger model of length-width ratio, and air outlet position along the long side of component
Put.Meanwhile, cleannes sensing device of the present utility model provides electric energy, battery using internal photovoltaic module for battery
It is that air pump and data acquisition unit, display unit and data communication unit provide electric energy, without external power supply, installs and uses very
It is convenient.
Brief description of the drawings
Fig. 1 is the component connection diagram of the net formula photovoltaic module cleannes sensing device of gas of the present utility model.
Embodiment
