2. SOLAR PUMP
A solar-powered pump is a pump running
on electricity generated
by photovoltaic panels
Flat-plate collector is used to absorb the
sun’s energy to heat the water.
Heat exchangers used to transfer solar
energy absorbed in solar collectors to the
liquid or air used to heat water
Collector collects heat by absorbing
sunlight

4. WorkingPrinciple
Solar flat-plate collector arrays are installed
to heat water or an organic fluid
Hot water flows to mixing tank or storage
tank
Hot water then flows to heat exchanger
It converts the working fluid of heat engine
or turbine from liquid to vapour
Working fluid(R-115) Low cost & high
efficiency.
5. Hot water again fed into collector by
circulating pump
The vapour is discharged from the turbine or
heat engine
That vapour flows into condenser where the
vapour gets condensed.
The working fluid is fed into heat exchanger
through feed pump to complete the cycle
The water which is pumped is used as a
coolant in condenser of the heat engine
6. Advantages
High efficiency heat engine is achieved by
high temperature in heat engine
Optimum range of operating temperature is
used in solar pumping system to attain
maximum efficiency
Energy efficiency= % of solar energy
collected with quantity which convert into
useful work(14%)
