1. Solar water pumps can provide water in remote locations without access to power lines and are more economically and environmentally friendly than diesel pumps. 2. A solar water pump system uses photovoltaic panels to generate electricity to power an electric pump. The water is pumped into a storage tank for gravity feed. 3. While initial costs may be higher, solar pumps have lower long term costs than diesel pumps due to no fuel costs and require little maintenance. They provide environmental benefits by reducing greenhouse gas emissions.

5. A reliable and clean water supply is an essential need but a large number of
people currently lack this basic provision. Solar water pumps is a socially and
environmentally attractive technology to supply water. Especially if the need
for water is in remote locations which are beyond the reach of power lines,
solar power is often the economically preferred technology. Solar water
pumps can supply water to locations which are beyond the reach of
power lines. Commonly, such places relies on human or animal power or on
diesel engines for their water supply. Solar water pumps can replace the
current pump systems and result in both socio-economic benefits as well as
climate related benefits. The water supplied by the solar water pump can be
used to irrigate crops, water livestock or provide potable drinking water.

6. A solar water pump system is
essentially an electrical pump
system in which the electricity
is provided by one or several
PhotoVoltaic (PV) panels. A
typical solar powered pumping
system consists of a solar panel
array that powers an electric
motor, which in turn powers a
bore or surface pump. The
water is often pumped from
the ground or stream into a
storage tank that provides a
gravity feed, so energy storage
is not needed for these
systems. A typical installation is
illustrated in Figure.

7. The vital merit of using a solar
powered shallow is that it will
not require any power supply.
As a result it can be used in
many remote locations where
grid power is not available. It
also helps to conserve energy.
So it will be more
economically suitable for the
rural population.

8. The main advantage and disadvantages are
categorized below
Advantages Disadvantages
 - Low maintenance  - Potentially high initial
- No fuel costs or spills costs
- Easy to install - Lower output in cloudy
- Simple and reliable weather
- Unattended operation - Must have good sun
- System can be made to exposure between 9 AM
be mobile and 3 PM

9. Other Contributions
1.CONTRIBUTION OF THE TECHNOLOGY TO SOCIAL DEVELOPMENT
SOLAR WATER PUMPS CONTRIBUTE TO SOCIAL DEVELOPMENT IN SEVERAL WAYS.
SINCE OTHER REMOTE WATER SUPPLY SYSTEMS ARE LESS RELIABLE THAN SOLAR WATER
PUMPS. THE USE OF SOLAR WATER PUMPS THEREFORE PROVIDES A RELIABLE, SAFE AND
ADEQUATE WATER SUPPLY WHICH IMPROVES THE COMMUNITY'S HEALTH
2.CONTRIBUTION OF THE TECHNOLOGY TO PROTECTION OF THE ENVIRONMENT
WHEN SOLAR WATER PUMPS REPLACE EITHER DIESEL GENERATED ELECTRICITY OR GRID BASED
ELECTRICITY, THERE ARE CERTAIN CLIMATE RELATED BENEFITS. A DIESEL GENERATOR EMITS CO2 DURING
OPERATION AND GRID BASED ELECTRICITY IS USUALLY GENERATED WITH EITHER COAL, OIL OR NATURAL
GAS WHICH ALSO EMITS CONSIDERABLE QUANTITIES OF CO2. IN CONTRAST. A SOLAR BASED WATER PUMP
SYSTEM DOES NOT RESULT IN GREENHOUSE GAS EMISSIONS. EXTENSIVE USE OF SOLAR WATER PUMPS
WOULD THEREFORE LEAD TO SUBSTANTIAL GREENHOUSE GAS EMISSION REDUCTION.

10. BUT THE VITAL QUESTION IS :

11. And the answer to the previous
question is both yes and no.
At first your initial capital cost will be higher than other usual machines
because of several aspects of the machine(viz. size, insolation level,
pumping head etc).
While system size and insolation levels greatly influence the capital costs of
a solar shallow, the operational costs of the system are generally very low
due to low labor and maintenance costs. In contrast, inexpensive diesel or
gas generators have low initial capital costs but require constant
maintenance and the parts have shorter lifetimes which increases operating
costs. This long-term economic advantage makes solar water pumping more
cost-effective to conventional pumping systems, such as diesel and
electrical pumps . A study by the Bureau of Land Management showed that
certain Solar systems cost only 64 % over twenty years compared to a
generator system did over ten years

13. CONCLUSION:
Solar power is the modern energy source of India. As
there is a huge shortage of conventional energy
sources in India, anything that can replace today's
machines with non-renewable energy sources is
definitely a good investment. In India there are many
remote places which lack the availability of
electricity, in those regions the only alternative will
be solar energy. As a whole, Solar Shallow will not
only decrease financial problems but also it will
increase agricultural productivity and benefit on
much more aspects.
