SOLAR WATER PUMPING

There are 20 million water pumps running in India for irrigation. Half of them are running with grid power and remaining are diesel operated. All these pumps can be converted to solar power in 4 to 5 years only. Farmers can not afford to buy heavily expensive diesel. Government is not very keen to switch on to solar power. Subsidy scheme is illusive and it is given to a few hundred farmers only. It can not cover even 1% farmers. In fact, Government policy is not farmers friendly. They do not need subsidy. They need loan facility with negligible interest to purchase solar panels and inverters. Solar water pump is nothing but…. solar power plant connected with electric motor and pump. Solar power plant is only solar panels and inverter. Most of the pumps are 3 hp to 10 hp. If water is shallow in well or pond or canal or reservoir or river etc, water head will be very small and hence small electric motor such as 2 hp or 3 hp or 5hp will be enough for running the pump. Accordingly smaller panels of 2 kw to 5 kw will be quite enough.   For deep water, submersible pump of 7 to 10 hp is required. So you have to simply connect water pump to proper size of solar power plant.

So solar water pump is extremely simple.

It is fully automatic. No operator required.

solar panels occupy only negligible area.

Appropriate size of inverter controller is attached to solar panels to provide 3 phase AC power.

It can be installed in 3 days only.

Once installed, it goes on working for 20 years.

So free electricity for 20 years.

10 KW solar power plant produces at least 18000 KWH power in a year.

Only power selling fetches Rs 110000/-.

So 22% return on investment.

So it is economically viable.

But if you utilize solar power for water pumping, benefit will be far more.

PRICE LIST OF SOLAR WATER PUMPS

(1) 3 KW SOLAR WATER PUMPING SYSTEM consisting of

(a) 12 nos of high voltage solar panels of 250W each, Made from first grade polycrystalline solar cells, size of panel about 1.5 mt x 1 mt. Every Solar panel is supplied with test certificate.

(b) supporting steel structure which is to be revolved against sun occasionally OR to be fixed permanently with ground. Permanently fixed solar panels give 71% power, while if you purchase revolving and tilting structure and focus it only 3 times in a day, you get 85% power.

(c) Inverter controller to convert DC power of low voltage to AC power of high voltage of 415 V, 3 phase power. It is highly advanced electronics technology with all types of protections and facilities. ( It also can be connected with your smart mobile phone to get at every moment data of power generation in your solar power plant.)

(d) submersible pump suitable for open well or bore well of 3 hp. Shipment volume 4 cu mtr. Pipe line, cables not included. It is commonly available everywhere. COST EX FACTORY RAJKOT = Rs 220000/- + 5% tax. (US$ 4500/-) If you select fixed structure, then you can fabricate it locally. It will be cheaper to you. Then plant cost will be reduced to Rs 170000/-+ 5% tax. i.e. 12 panels + inverter + submersible pump only.

(2) 5 KW SOLAR WATER PUMPING SYSTEM consisting of

(a) 20 nos of standard solar panels of 250W each, Made from first grade polycrystalline solar cells, size of panel about 1.5 mt x 1 mt. Every Solar panel is supplied with test certificate.

(b) supporting steel structure revolving on dual axis manually – 2 sets of 10 panels each which is to be revolved against sun occasionally. Permanently fixed solar panels give 71% power, while if you purchase revolving and tilting structure and focus it only 3 times in a day, you get 85% power.

(c) Inverter controller of 5 kw to convert DC power of low voltage to AC power of high voltage of 415 V, 3 phase power. It is highly advanced electronics technology with all types of protections and facilities. ( It also can be connected with your smart mobile phone to get at every moment data of power generation in your solar power plant.)

(d) submersible pump suitable for open well or bore well of 5 hp. Shipment volume 5 cu mtr. Pipe line, cables not included. It is commonly available everywhere. COST EX FACTORY RAJKOT = Rs 320000/- + 5% tax. (US$ 6000/-) If you select fixed structure, then you can fabricate it locally. It will be cheaper to you. Then plant cost will be reduced to Rs 270000/-+ 5% tax. i.e. 20 panels + inverter + submersible pump only.

(3) 10 KW SOLAR WATER PUMPING SYSTEM consisting of

(a) 40 nos of standard solar panels of 250W each, Made from first grade polycrystalline solar cells, size of panel about 1.5 mt x 1 mt. Every Solar panel is supplied with test certificate.

(b) supporting steel structure revolving on dual axis manually – 4 sets of 10 panels each which is to be revolved against sun occasionally. Permanently fixed solar panels give 71% power, while if you purchase revolving and tilting structure and focus it only 3 times in a day, you get 85% power.

(c) Inverter controller of 10 kw to convert DC power of low voltage to AC power of high voltage of 415 V, 3 phase power. It is highly advanced electronics technology with all types of protections and facilities. ( It also can be connected with your smart mobile phone to get at every moment data of power generation in your solar power plant.)

(d) submersible pump suitable for open well or bore well of 10 hp. Shipment volume 8 cu mtr. Pipe line, cables not included. It is commonly available everywhere. COST EX FACTORY RAJKOT = Rs 580000/- + 5% tax. (US$10300) If you select fixed structure, then you can fabricate it locally. It will be cheaper to you. Then plant cost will be reduced to Rs 490000/- + 5% tax. i.e. 40 panels + inverter + submersible pump only.

Delivery

We can dispatch the equipments within 7 days without structure.

We can dispatch the equipments within 15 days with revolving structure.

On 25-10-2015, we commissioned 3 kw solar water pump in my factory. It was giving discharge of 460 lit per minute at 11-00 am. After 3-00pm, it starts reducing discharge and at 5-00pm it stops. Total water lifting for the day is 150000 ltr. i.e.150cu mt. I have fitted 12 nos of high voltage panels of 250W each and fixed with ground. If I keep revolving, discharge will be 25% more. Head is only 8 mt. I used high efficiency submersible pump. So performance is excellent. This will go on working for almost 20 years automatically. So this is really blessing. Those farmers who have to lift water from river, lake, canal or shallow wells, such solar pumps is blessing. I can supply solar water pumping system up 10 kw with high efficiency submersible pumps which you can not find throughout India. Inverter of this pump has facility to connect with mobile so that you can start and stop by mobile and get performance data by SMS even though you may be thousands of km away.

You can visit our factory for live demonstration of 10 kw solar power plant working for wheat grinding mill with revolving structure and 3 kw water pumping with fixed structure.
