Dear All,
We now successfully have launched 3 phase and single phase harmonic reactors which can be used in locations where the distance between the pump and the starter is large.
These harmonic reactors aid to reduce the harmonic distortion that occurs with long cable distances, thereby increasing the performance of the pump.
This can be connected to pumps irrespective of whether it is run on solar or grid.

hey!
sorry for the delay.
my drip/foggers need a pressure of 2kg/feet to open and start operating. the setup of this is spread in an area of about 80 mtr x 90 mtr or so.
can your product be customised to create this amount of pressure so i can get what i am looking for ?
also i am interested in running these motors remotely / automatically. can that be done with the help of your company or i need a software and hardware specialist team for that?
and lastly, can this setup be connected to a storage device ? if yes, what would be the price for the setup i am looking for and the maintenance issues related to it.
ohh, and how do these solar motors perform in rains and cloudy weather?
Vivek
Hi Vivek,
As mentioned in my earlier posts, solar water pumping is a variable pressure system, i.e delivery will depend on the amount of irradiation available at your site.But having said that, yes we can customize the solution for constant pressure based on your requirement. For this we need your motor’s rated Hp, Voltage range & current.
Also, the solution as such can be programmed to run automatic (starts when sunlight is powerful enough for the motor’s starting torque and shuts down when the power falls) or manual as well. Remote start/stop is generally possible for grid connected 3 phase pumps but in case of solar pumping, this works only when the power is max i.e when radiation is at its best.
Lastly, connecting batteries for power storage is not advisable in case of inductive loads like motors, as the charging and discharge cycles will be very abruptive leading to wear and tear and regular maintenance & replacement costs.
Solar powered water pumps perform even during cloudy or rainy reasons except that the output will vary depending on sunlight’s intensity.

thanks for the further details.
my main worry is will it be able to create a operating pressure for a 80x80 mtr drip setup? which is 2kg/feet
also my drip time is fixed to early morning, so the sunlight may/maynot be available, at the time of requirement all year round.
and i do not want a auto on/off system depending on the sunlight/power, but my schedule and requirement.
the motor hp is 3 & 5, i dont understand current and voltage range, if you would be patient enough to explain how to measure it, i can get back to you in 2-3 days time.
i really am confused.
You may want to re-plan the whole thing. Consider building an overhead (or over the hill) tank if possible. In that case you can reduce the pump HP drastically (hence the cost of solar panels), since all the you need to do is to fill the tank over a period of say, 6 hours (minimum) per day. Once the tank is full, you can irrigate whenever you want.
sounds very money involving and a bit of a pain.
i guess diesel power is more suitable for my needs.
any idea if i can use wind power? 
i think the diesel option would be more economical.
Hi Vivek,
I can understand.
For drip setup to run on solar we have 2 options;
A)Add atleast 25% more solar panels to the rated Hp so that you could have a constant pressure throughout the day, the early hrs will also yield more power as we have 25% additional solar panels
mpneerkaje was spot on.
B)Have a farm pond or a intermediate reservoir, where you can have your borewell pump fill up during non peak hours and you could run a openwell pump and drip irrigate on solar
We just completed a project successfully;let me explain the setup of the same
Client has a borewell of 580ft depth and a sump of storage 2.5Lakh Litres . He proposed for having a solar setup that could drip irrigate his 10acre field.
We suggested 4hp submersible bore pump and 3hp openwell pump and 5000watts of solar panels. The idea is to run 4hp pump when drip is not done and when drip has to be done he can change over to 3hp openwell pump.Point to be noted is, since we have additional 1000watts for 4hp and 2000watts in case for 3hp, the power loss during non-peak hours can be compensated and these panels are monocrystalline.
What I can suggest you is;
I presume you dont have an intermediate tank. So you could probably have solar monocrystalline panels of capacity 5000watts and a 5hp solar pump controller configured for running anyone pump at a time i.e both 3 & 5hp connected to this setup.
You can run 5hp during peak hours and remaining hours you can run 3hp as power generated by 5Kw panels during non-peak hrs will be sufficient enough for running your 3hp pump.
Please share your email Id so that I can send you the details, if you wish to know more.
Also, running on wind is as same as solar, because power generated will be variable, so will be the delivery.
DG will give constant power, but the cost you would incur and the maintenance issues would need to be seen.

Also, Vivek
Please find attached a article on diesel Vs solar published by EAI, where I happen to be a member as well.
Its worth a read.
