Solar Power Solution and Solar Pumping Solution Purchase Guide

Dear All,

I just wanted to share with you all a brief purchase guide for solar water pumping and solar power solutions.

I hope you find this useful in your decision making.

Let me share with you what I can based on my limited knowledge:

The bottomline in any purchase is to lookout quality, cost & proven track record that a seller offers. And there are few specific parameters on which you can compare quality and cost offered by companies.

How to compare offers for solar power solutions with battery backup:

Quality Parameters to keep in mind:

Monocrystalline panels are superior in quality as against polycrystalline panels
Solar Power conditioning unit is the advanced model as against solar inverter
IGBT based Solar Power conditioning unit is always high efficient and robust when compared to MOSFET based Solar Power conditioing unit
MPPT is better than PWM charge controller
Aluminium structure is rust proof when compared to MS/ MS galvanized structure
Solar cables have long life /weather proof and have less/zero power loss against regular AC cables
C10 rated solar batteries offer longer life less maintenance against C20 UPS batteries
Using MC4 connectors and branch connectors avoids taping joints and useful in the long run because of no wear and tear
Never allow anyone to parallel the batteries as this will reduce the life of the battery due to internal resistance
Always insist on 5 years replacement warranty batteries and not 3 + 2 years warranty batteries

How to compare offers for solar pump solutions :

Quality Parameters to keep in mind:

Monocrystalline panels are superior in quality as against polycrystalline panels. But remember you can use monocrystalline panels for pump capacities exceeding 3Hp only in most of the cases.
Always ask for a pump controller that has inbuilt VFD and MPPT, (having dry run protection, voltage and current protection with all switch gear are optional but its better to have these). This will ensure your pump will run nonstop when sun shines without turning off . Having just a VFD will make pump work for say 10AM to 3PM and that too no guarantee for constant running.
Aluminium structure is rust proof when compared to MS/ MS galvanized structure
Solar cables have long life /weather proof and have less/zero power loss against regular AC cables
Using MC4 connectors and branch connectors avoids taping joints and useful in the long run because of no wear and tear

Cost Comparison:

After understanding which are the quality BoM from above explanation, ask for a quote for system using quality desirable materials and compare the cost.Make sure the quotation clearly mentions itemwise explanation

Track record:

After obtaining the quote, do insist on previous projects. Visit the project if possible and get the customer’s feedback on service and quality. 99% of the solar installations fail because of improper system design.

As a customer your duty:

Solar Power Solution:

Always be specific on your requirement. Example, if ask, if you can run your roasting machine on solar, the answer is YES. But for any company to offer a suitable solution this its not sufficient to have just this information. You need to let know the power rating of the machine or at the least the brand and model number.

If you are looking for a power solution always remember to give this below info:

a)What all loads you wish to run on solar and how many of each appliances?

Ex: 4 fans for 6 hr, 5 lights for 6 hrs, 1 tv for 2 hrs etc

b)Let the company know if you want these loads to be run on primary solar or backup solar

Solar Water Pumping Solution:

If you are looking for a pumping solution always remember to give this below info:

a)Correct HP rating of the pump
b)Whether the pump is single phase or three phase

Dear Sarvana
Thank you for posting.

I see that you offer both solutions.

Do you have solar pumps which can run 1 or 2 HP water pumps ? if yes, Please share the quotation.

We are looking at “economical” solution.

Dear AksPat,

Yes you are correct, we do offer solar water pumping solutions specifically through our product solar pump converter.
Solar Pump Converter. With this converter,Now you can convert your existing electrical submersible/monoblock/open-well 3phase pump to Solar powered/Diesel powered/Battery powered 3phase pump.

Current Scenario:

Solar Panels are connected to the pump through solar pump controller

Disadvantages - The pump runs at full rpm only when the solar power available is max which on an avg is between 10AM to 3Pm in most of the Indian cities. Also, even if there is a small amount of shade the controllers trips and needs to be manually turned ON again.

Our Solar Pump Convertor:

Our pump converter unit converts the electrical pump that can also run on solar/diesel engine/battery depending on user preference.

This innovative pump controller comes also with a inbuilt MEPT(Maximum Efficient Powerpoint Tracking) control instead of conventional MPPT for a improved performance and a longer run time of the pump.

The controller runs the pump at full rpm when solar is strong and it runs proportionate to the input power when solar is weak. The main advantage is that unlike the conventional controller’s the MEPT assures 1)Non Stop Operation of the pump without the control unit tripping 2)Longer run from avg 7AM to 6PM on Solar.

This also has multi mode input power supply option that can be changed manually between mains, solar, DG and Battery. Note: Battery & DG are optional

Some of the salient Features are:

Inbuilt flow detection function which turns off in case of dry run.
Lightining Protection
Undervoltage protection
Overvoltage protection
Overcurrent Protection
Undercurrent Protection
Short-circuit Protection

Product comes in 13 variants

  1. 0.5Hp
    2)0.75Hp
    3)1Hp
    4)1.5Hp
    5)2Hp
    6)3Hp
    7)4Hp
    8)5Hp
    9)7.5Hp
    10)10HP
    11)15hP
    12)20hP
    13)25hP

The 1hp and 2hp three phase converters are rated for output 415V AC 3 phase @ rated current 3.3A and 5.6A.

The converters are priced @ Rs.29,000 for 1Hp & Rs. 38,000 for 2Hp. Price inclusive of taxes. Exclusive of transport charged @ actuals.

All you need is connect panels using the schematic we provide and you are set to go green!

Its simple plug n play kit! A local electrician will be able to do it without hassles.

Dear saravan,

we have installed a Hydroponic machine in our farm.( it’s power requirement is 1ton a.c. x 2nos.+ 1no. 1/2 hp water pump + 40 Watts x 4nos. tube light.)

We are looking for a alternative cheap power options when Electricity is not there. ( generally, in our farm 17 - 20 hours power will not be there.) For that already we  are arranged alternative power source from biogas power for 8- 10 hours. For the balance i.e. around 8-10 hours, is there any chance of solar power solutions?

please let us know, in detail if it is possible.

thanks and regards,

kasturiraju.

Dear Mr.Kasturiraju,

Please be informed, anything that runs on power can be run on solar.

To size the solar solution and offer you a quote, I would require few more details. Like do you have an inverter connected to the biogas plant, do you have batteries and lot more details etc

May I request you to please share your number to my email saravana.kumar@greencurrent.in to have a brief discussion?

Thanks in advance,
