This document describes a solar pumping system. It uses solar flat-plate collectors to absorb sunlight and heat water. The hot water is then transferred via heat exchangers to a working fluid like R-115, converting it to vapor. This vapor powers a turbine or heat engine, which drives a generator to produce electricity. The electricity generated can then be used to power pumps, with the pumped water used as a coolant to condense the working fluid and complete the cycle. Key advantages are achieving high efficiency from the high-temperature heat engine and using an optimal operating temperature range to maximize efficiency at around 14% of collected solar energy converted to useful work.

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%)
