Technical field
The present invention relates to a kind of dust detection, be specially a kind of dust induction apparatus.
Background technology
Solar panel is by photoelectric effect or photochemistry by absorbing sunlight, by solar radiant energy
Effect is converted directly or indirectly into the device of electric energy, although the solar panel market demand in recent years
Very big, but the energy conversion rate of solaode is low always affects its key factor using and promoting,
Except the problem of the material such as monocrystal silicon and polysilicon itself is that energy changes low reason, another one causes energy
It is then that solar panel suffers dust covering that amount changes low factor, has a lot of related application examples at present,
When in February, 2004 " opportunity " number just starts mars exploration task, up to the solar-electricity of 1.3 meters above it
Pond plate can provide the electric energy of 900 watt-hours every day, but in June, 2013, along with " opportunity " number too
Sun can slowly be stained with Mars dust on cell panel, the electric energy that solar panel provides every day fall below 500～
600 watt-hours, to such an extent as to scientist NASA has to, by order, allow two Marsokhod rest in towards south as far as possible
Slope on so that they can receive more sunlight, the electricity that however Marsokhod provides every day
Amount still cannot improve.Due to the existence of this problem, many solar power plants are using certain time limit
Rear be badly in need of cleaning because accumulation over time, dust and sandy soil etc. fall in solar panel Back stroke no
Go, not only have a strong impact on generating efficiency, and surface dirt is to the open-circuit voltage of solar module, short circuit
The characterisitic parameter such as electric current and output also has a significant impact, by test result indicate that: short circuit current can be with
The increase of dust quality and reduce rapidly, and open-circuit voltage reduces relatively slow, the generated energy thus brought
Loss is up to 9%.Meanwhile, the sand and dust quantity in solar panel surface unit area, the comparison of sand and dust yardstick
Penetrate the wavelength at the light on solar panel surface also to have a significant impact；In addition, solar module
In use, if there being a piece of solaode individually to be blocked by leaves birds droppings etc., then be individually blocked
Solaode will generate heat damage under sunburst irradiates, and then cause whole solar module
Damaging, here it is so-called tropical island effect, these all can cause imponderable infringement to solar panel.
