Solution Abstract
High energy demand is leading to the replacement of fossil energy
with renewable sources such as solar energy. Solar cells are devices
used to generate solar energy but due to Dust deposit on the
surface of the solar panels reducing the intensity of the solar
radiation that reaches the photovoltaic cells and also increase
temperature that reduce the performance of solar PV panel and
mirror. Therefore the solar panels and mirror need to be cleaned
from time to time to minimize efficiency losses.
With a view to overcome the problems associated with conventional
solar panel cleaning methods for both rooftop and ground mount
installations, here is a novel method which is fully autonomous to
work in any environment, tilt or mounting structure, Which required
only natural air to work 24x7 without any operation or manual
interface.
This will be done by using a tangential Fan blade which is
Specifically Designed to Create A Powerful Stream of Air that work
as a Uniform, Noiseless and Invisible Barrier along the solar PV .
This High Velocity Cushion of Air will Helps to clean and Prevent
Dust accumulation on Solar PV and also increase power output in
different ways. By cleaning, cooling, and increasing intensity of
light.

The system will give best result compare to robot cleaning
solution for inclined mounted solar PV panel or mirror as it does not
required any energy so it will work as a passive cleaning
solution, Which is not yet exist?
Important Note -
When more photons falls on solar cell, which result in high extraction of
electrons and consequently higher short circuit current with increase of air
pressure i.e. air pressure is directly proportional to intensity of light and
intensity of light is directly proportional to power output of solar panel.
Solution Conclusion
Simple anhydrous and low cost solutions that will effectively mitigate the
soiling impact on the PV panels and flat solar mirror Implementation of solution
in each row of inclined solar PV cell or mirror.
Multiple unit needed to be installed same as solar PV installed in series
The aerodynamically design ( air inlet and air outlet area ) PVC pipe (150 mm)
Tangential fan blade (100mm ) placed and fitted inside in such a way only fan
blade will move on bearing , then prepared pipe will be mounted on top of solar
panel. With existing back side metal frame support .
As n when wind start blowing air will enter through air inlet to inside the pipe
once fan blade start moving suction pressure buildup inside the pipe further
more air will pass through cross flow fan that will propel the speed of
tangential fan blade and blade will start moving like wind turbine as a result
high pressure air will start coming out .(as outlet area is very narrow
compare to inlet area) constant pressurized air flow will creates air curtain/
barrier only above solar panel surface which act as a dust cleaning and anti
dust system even if some dust remain so then further, whenever wind blow
with high velocity it will remove accumulated dust from solar panel pave or
mirror. Whenever in a day wind velocity will be at peak it will remove almost all
the dust which is accumulated in whole day.. As in night when panel is not
operational however dust accumulates whole night so in morning we have
large amount of dust to clean. By using this solution dust accumulation won’t
be much because system will blow the air constantly.
Important Note -When more photons falls on solar cell, which
result in high extraction of electrons and consequently higher short circuit
current with increase of air pressure i.e. air pressure is directly

proportional to intensity of light and intensity of light is directly
proportional to power output of solar panel.
