FABRICATION OF SOLAR FERTILIZER SPRAYER | We, Mechanical farm, provide the widest list of mechanical engineering final year project and Automobile Engineering project topics and reports. Also, we have a great variety of pre-made Solar project kits using solar panels, batteries, Inverter, LEDs for you to use in your projects.


one of the most frequently occurring problems in  all the conventional type of   that cannot provide enough advantages as listed below  because of old manufacturing and old design.
So we planned to assemble the modern model of agriculture spraying machine pump with the additional advantages .
There are few problems for operators to handle the conventional device are which had listed and studied deeply and few conclusions as well as solutions are made. Right accordingly to above solutions the design procedure had also been started.


By taking into consideration  above all discussion about the disadvantages is  to be realize and the deep study of is  done and the most difficulty or challenge  was that the all above disadvantages were to overcome the  with the decrease in  cost  because  our working mode is going to use in the agricultural field . 
Another one problem was that the operator (farmers)  are less skilled worker   We design a spray which works on solar energy., it based on the renewable energy source. It’s a master technique which do not want any kind of energy and takes only sunlight for its working and application.
As above mentioned there are few more disadvantages of conventional the hand-operated spray pump.  Some of them are listed below.  
1)         The  hand-operated  spray  pump  are  unaffordable
2)         In  case  of    hand-operated  spray  pump, the  maintenance  required
3)The hand-operated spray pump are not user-friendly.
4) Only a skilled  operator  can  use  the  hand-operated  spray  pump
5) There  is  no  special  arrangement  for  storing  of  pressure  in case  of  The  hand-operated  spray  pump 
6)   The hand-operated spray pump cant handle the large pressure.
7)  The system is  quite  bulky


A solar panel is fitted on the helmet  that is expected to wear by the farmer while spraying. Step by step procedure for working principle.
1. tank is filled with mixture of  pesticide and water
2. Solar radiation incident on solar panel it will absorb this radiation and produces the   current with the help of semiconductor .
3.Control system control the voltage and this voltage supply to battery and battery     store output of control system
4. motor is operated by battery and is provided to start the motor
5. pump lift the  pesticide supplied towards the nozzle  through pipe
6. nozzle sprayed or distribute pesticide on the crop at uniform pressure
7.mixture of water and pesticide is distributed on crop with the help of hand notch.
   It’s working on electrical energy which is generated by solar panel. It is converted in to mechanical energy and pump is operated for spraying pesticides.


1.    Agricultural  application for  spraying
2.    Municipal  application  like  for  spraying  the  mosquito  controlling  medicines and  etc.  
3.    House  holding  as  well  as  office  paste  controlling
4.    Gardening  and  other  related  applications.
5.    Cleaning  of  all  sort  of  glasses(buildings)
6.    Large  capacity  lubrication  units.
7.    Commercial  plants  nurseries.


1)     No running cost.
2)     Renewable energy sources gets utilized.
3)     No residual produced 


1)     Battery requires maintenance.
2)     Initial cost is high.
3)     Low response in cloud atmosphere.
