- Solar powered irrigation systems use photovoltaic (PV) solar panels to generate electricity to power water pumps for irrigation. The electricity is provided without fuel costs and the systems can operate indefinitely as long as there is sunlight. - The key components are solar panels, a controller, storage tank, and submersible or surface pump. Solar pumps can supply water to remote locations not reachable by power lines and provide a reliable source of power with low maintenance costs compared to diesel pumps. - Advantages include saving on energy costs, no dependence on electricity grids or rain, and enabling increased crop yields. Disadvantages are higher upfront costs and pumps not operating at night. Larger solar arrays are needed for high power

2. What
• A solar water pump
system is essentially
an electrical pump
system in which the
electricity is provided
by one or several
Photo Voltaic (PV)
panels
Where
• Solar water pumps
can supply water to
locations which are
beyond the reach of
power lines/
frequent power
cuts/Power is not
enough
Why
• Large reduction in
carbon emission
• Early pay back
period
• Long Life (Around 25
Years)
• Reliable source of
power supply
• More saving due to
low maintenance
• low yielding
borehole has time to

4. ADVANTAGES
• It helps in saving energy.
• There is no fuel cost - as it uses available free sun light.
• No electricity required.
• Can be operated lifelong.
• It works everywhere.
• It is also useful for clean, drinking water sanitation and also irrigation.
• The dependence on rain is reduced
• It creates wealth for farmers by increasing no. Of crops.

5. DIS-ADVANTAGES
• High initial cost
• Non-working at night
• Solar panel inefficiency. (A solar panel Can convert < 22% of the energy
it gets from the sun into electrical energy)
• Bulky solar panels are required for the
• Large power production

6. WHAT ARE SOLAR POWER PANELS?
• A solar power panel is made of photovoltaic cells arranged in a configuration that can contain 32, 36,
48, 60, 72 and 96 cells.
• A solar panel comprising 32 cells typically can produce 14.72 volts output (each cell producing about
0.46 volt of electricity).
• These cells are arranged in a frame that is either rectangular or square.
• The size and weight of solar power panels increase as the number of cells increase.
• Solar power panels with higher cell configuration are used in commercial applications to generate
electric power.

7. HOW DO SOLAR POWER PANELS WORK?
• The cells in a solar power panel are photovoltaic, they absorb energy from the
sun’s rays when exposed to the sun.
• This energy is transferred to the semiconductor creating an electric field
delivering voltage and current.
• Power is derived from the equation P (power) = V (voltage) x i (current). for
instance, a solar power panel comprising 72 cells generates 33.12 v.

8. FEATURES OF SOLAR POWER PANELS
• Solar power panels can come in varying sizes but the common size for commercial applications is
77 x 39 inches and for residential applications, the common size is 65 x 39 inches.
• The size of an average solar panel is dependent on the number of cells (1 cell = 15.6 x 15.6
cm) encapsulated in it and the panels' application.
• The cells produce relatively constant voltage but current can vary with the intensity of light falling
on the solar power panel.
• Photovoltaic solar panels can come in three types – monocrystalline silicon PV panels,
polycrystalline silicon PV panels and amorphous or thin film solar PV panels.
• A typical solar power panel can generate 230 to 325 watts of power.
• Any power generated can be used directly to charge a device that runs on DC current.
• By using an inverter, DC power can be converted to AC to run devices that use AC current

14. Difference between Mono-crystalline
and Poly-crystalline solar cells
• Price - monocrystalline solar panel price is more than that of polycrystalline solar panel price
• Efficiency falls in the 15-20% range while that of polycrystalline panels falls in the 13-16%.
• Mono-crystalline panels are blackish while polycrystalline panels are blue in color
• Monocrystalline panels enjoy a little longer lifespan than polycrystalline solar panels.
