Farmers Proposition for using Solar Vs Diesel Pump.
Assumptions
Cost of 5 HP diesel pump set 55000
Cost of 5HP Solar PV water pump 550000
No of Days of operation for Diesel Pump Set 115 days
No. of operating hours per year 6.5 hrs/day 748 hours
Cost of diesel/litre 60
Fuel consumption/hr. Of 5kVA DG set 2.5 litres
Maintenance cost/year for diesel pump 5000
Maintenance cost/year for solar pump 1000
Life cycle period (in years) 10 years

So for SPV Pump 10 year cost of ownership comes to
Capital Cost 550000
Net Present Maintenance Cost 6000
Net Present Fuel Cost 0
Total 556000

Similarly for diesel Pump 10 year cost of ownership comes to
Capital Cost 55000
Net Present Maintenance Cost 30000
Net Present Fuel Cost 1178100
Total 1263100

This is only a 10 years comparison where inflation in price of Diesel is not considered. In the year 1994 which is exactly 20 yrs back diesel was sold at Rs 6.98/lit. Now the same stands at Rs60/liters.

Comparison of Solar and other Remote Watering Options
Pumping Technology

Advantage Solar
-Low maintenance
- No fuel costs or spills
- Easy to install
- Simple and reliable
- Unattended operation
- System can be made to be mobile

Disadvantages
- high initial costs
- Lower output in cloudy weather,

Diesel
- Moderate capital costs
- Can be portable
- Extensive experience available
- Easy to install

Disadvantages
- Needs maintenance and replacement
- Maintenance often inadequate, reducing lifetime of system
- Fuel expensive and supply intermittent
- Noise, dirt and fume problems
- Life time cost of running makes it the most un viable option

3. Is a solar water pump system more expensive than a “conventional” system?
Where utility power isn’t readily available solar systems are often the most economical option. Factoring in ALL costs, such as installation, fuel, maintenance and waste, solar water pumping is often less expensive than generators, windmills, and running electrical lines. With a solar water pump system a customer has an accurate forecast of the cost to run and maintain their pump system because they have paid their energy costs “up front.” There may be tax credits and incentives that lower investment costs.

What happens when the sun doesn't shine?
Depending on the application, a solar pumping system may use a water storage tank, which acts like a “Water Battery“during cloudy weather.

How does a solar pump work?

A solar electric array generates electricity from the sun’s light with no moving or wearing parts. A solar pump is designed to utilize the direct current from the array efficiently, even as the energy production varies throughout the day.

Solar Water Pump
A photovoltaic solar powered pump system has three parts:
• the pump
• the controller
• solar panels.
The solar panels make up most of the systems cost. The size of the PV-system is directly dependent on the size of the pump, the amount of water that is required (m³/d) and the solar irradiance available.
The purpose of the controller is twofold. Firstly, it matches the output power that the pump receives with the input power available from the solar panels. Secondly, a controller usually provides a low voltage protection, whereby the system is switched off, if the voltage is too low or too high for the operating voltage range of the pump. This increases the lifetime of the pump thus reducing the need for maintenance.
Voltage of the solar pump motors can be AC (alternating current) or DC (direct current). Direct current motors are used for small to medium applications up to about 3 kW rating, and are suitable for applications such as garden fountains, landscaping, drinking water for livestock, or small irrigation projects. Since DC systems tend to have overall higher efficiency levels than AC pumps of a similar size, the costs are reduced as smaller solar panels can be used.
Finally, if an alternating current solar pump is used, an inverter is necessary that changes the direct current from the solar panels into alternating current for the pump. The supported power range of inverters extends from 0.15 to 55 kW and can be used for larger irrigation systems. However, the panel and inverters must be sized accordingly to accommodate the inrush characteristic of an AC motor.

A solar water pump is a pump running on electricity generated by photovoltaic panels from the sunlig

A solar-powered pump runs on electricity generated by photovoltaic panels or the thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps. The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact than pumps powered by an internal combustion engine(ICE).

Most of the village people depend on the agriculture and due to the high power outages, villagers need to depend on the diesel generators for cultivating the crop which is borne to additional cost and the environment is spoiled by release of CO2. During the Power supply there is plenty of pump loads on the transformer which is causing the transformer fail.
