Background technology
Photoelectric cell is to utilize photovoltaic effect directly to be transformed into light the device of electric energy.Because it is widely used in the direct power transformation ability of a sun power, therefore is called solar cell, solar-energy photo-voltaic cell again.At present, use the most extensively, the most rising be silicon photocell.The theoretical value of silicon photocell conversion efficiency, maximum can reach 24%, and in fact only reaches 10%～18%.Yet this efficient of 10%～18% also differs and utilizes fully surely, because solar cell has deadly defect: dust.It sun can have a condition precedent in battery installation aspect, must be installed in outdoor roof in the open exactly.High-altitude or spacious place to accept sunshine to greatest extent, effectively bring into play its maximum photoelectricity or photo-thermal conversion performance.So dust in the atmosphere, foreign material will have a strong impact on the conversion efficiency of its photoelectricity, photo-thermal attached to its surface, reduce its usability, and the dust of very small amount (4.5g/m2) just can let the energy transformation ratio of solar panel reduce by 40%.If common solar panel three months is unclean, solar conversion efficiency can drop to below 9%.
The utility model content
In view of this; The purpose of the utility model is to propose a kind of solar cell dust monitoring device; When certain degree is arrived in the dust deposit of solar cell surface; Can send the dedusting prompting to the user,, make solar cell remain on the duty of high conversion with timely cleaning solar cell surface.
A kind of solar cell dust monitoring device according to the above-mentioned purpose proposition; Comprise: first solar panel and second solar panel; Both are electrically connected on the test circuit, and said first solar panel exposes externally in the space, and the said second solar panel outside is provided with one and hides dust hood; This hides dust hood closure under first state; This second solar cell is wrapped in the confined space that hides dust hood formation, opens under this screening dust hood and second state, and this second solar cell is exposed to space outerpace.
Optional; Said test circuit comprises first voltage test device, second voltage test device, divider, comparer and warning device, and said first voltage test device is connected on first solar panel; Said second voltage test device is connected on second solar panel; Said divider is connected on this first voltage test device and second voltage test device, and said comparer is connected on this divider, and said warning device is connected on this comparer.
Optional, said screening dust hood has foldable structure, and this foldable structure is connected on the motor.
Optional, also comprise timer, be connected on this motor.
The utility model is elaborated with specific embodiment below in conjunction with accompanying drawing.

Fig. 2 is the second cell panel structure synoptic diagram of the utility model;
Fig. 3 is the structural representation of the test circuit of the utility model.
Embodiment
See also Fig. 1, Fig. 1 is the solar cell dust monitoring device synoptic diagram of the utility model.As shown in the figure, this solar cell dust monitoring device 1 comprises first solar panel 10 and second solar panel 20, and both are electrically connected on the test circuit 30.This first solar panel 10 is a reference plate, and it is placed in the space outerpace, and is consistent with the residing environment of solar battery product, and promptly the accumulation situation of the dust deposit situation on first solar panel, 10 surfaces and solar battery product is consistent.Thus, when the solar battery product surface causes transformation efficiency to reduce because of long dust deposit, this first solar panel 10 also will receive the influence of dust and reduce transformation efficiency.
See also Fig. 2, Fig. 2 is the second cell panel structure synoptic diagram of the utility model.As shown in the figure, this second solar panel 20 is placed in the confined space that hides dust hood 21 formation, and this screening dust hood 21 comprises folding structure 211, placement space 212 and motor 213.Under first state, folding structure 211 closures are wrapped in this second solar panel 20 in the confined space that hides dust hood 21 formation.Under second state, folding structure 211 is opened under the driving of motor 213, makes this second solar panel 20 be exposed to space outerpace.Like this, second solar panel 20 is being hidden in the confined space usually, can not suffer the pollution of dust.When needs carry out the test of dust, open and hide dust hood 21, expose second solar panel, owing to the difference that has conversion efficiency this moment between first solar panel 10 and second solar panel 20, both output powers are just different naturally.
Further; On motor 213, connect a timer 214; Set a set time, such as every month 1 time or each season once, this solar cell dust monitoring device can be opened automatically hide dust hood and carry out the dust test; The repeatedly unlatching that can avoid improper operation to cause, the average energy consumption of minimizing monitoring device.
Please again referring to Fig. 3, Fig. 3 is the structural representation of the test circuit of the utility model.As shown in the figure, this test circuit 30 comprises first voltage test device, 31, the second voltage test devices 32, divider 33, comparer 34 and warning device 35.
Said first voltage test device 31 is connected on first solar panel 10, in order to testing the output voltage of this first solar panel 10, and to this divider 33 outputs first voltage signal.
Said second voltage test device 32 is connected on this second solar panel 20, in order to testing the output voltage of this second solar panel 20, and to this divider 33 outputs second voltage signal.
Said divider 33 is connected on this first voltage test device and second voltage test device; Accept the first above-mentioned voltage signal and second voltage signal; And two voltage signals are carried out division calculation, obtain the ratio of output voltage of output voltage and second solar panel 20 of first solar panel 10.And to these comparer 34 these ratios of output.
Said comparer 34 is connected on this divider 33, accepts the ratio that this divider 33 provides, and this ratio and a reference value are done comparison, and comparative result is exported to warning device 35.This reference value preestablishes at this comparer 34.
Said warning device 35 is connected on this comparer, accepts above-mentioned comparative result.When this comparative result is a ratio during greater than reference value, the transformation efficiency that first solar panel 10 is described still maintains one, and the dust of surface sediment is not enough to influence its use than on the higher level, and warning device 35 does not send alerting signal.And when this comparative result be that ratio is during less than reference value; Explain that the dust of piling up on first solar panel 10 has surpassed certain degree; Cause the transformation efficiency of first solar panel 10 extremely low; Be that solar battery product is polluted by identical dust also, have a strong impact on the utilization of whole solar cell product.At this moment, warning device 35 sends alerting signal, and the prompting personnel should carry out the surface clean work of solar battery product, in time knows the dust that falls to be deposited in the surface, recovers the transformation efficiency of solar battery product.
In sum, the utility model provides a kind of solar cell dust monitoring device, this monitoring device utilizes two solar panels, and one is placed on and makes its pollution that suffers dust in the space outerpace, and other one then is placed in the confined space, keeps clean.When needs detect; The output voltage that compares two solar panels; If both differ too big, explain that then the solar panel surface dirt accumulation that is exposed on the external in the space is serious, need to clean; This moment, personnel can guarantee the transformation efficiency of solar battery product according to this result to the operation that solar battery product cleans dust.
By the detailed description of above preferred embodiment, hope can be known the characteristic and spirit of describing the utility model more, and is not to come the claim scope of the utility model is limited with the above-mentioned preferred embodiment that is disclosed.On the contrary, its objective is that hope can contain in the scope of the claim that is arranged in the desire application of the utility model institute of various changes and tool equality.
