4. • In RAJASTHAN solar radiation is
high about
6.2 – 6.4 kWh(m2)daily.
• Solar radiation is important for
photovoltaic energy

5. Solar Energy
Solar energy Originates with the thermonuclear fusion reaction
occurring in the sun.
• The sun delivers its energy in two main forms: heat and light

6. This Solar Radiation create two types of effects normally
Photoelectric Effect

7. Photovoltaic Effect
• In order to generate power, a voltage must be generated as well as a
current. Voltage is generated in a solar cell by a process known as the
"photovoltaic effect“.
• A silicon wafer behaves normally as a photoelectric effect. So use of
impurities in it.

12. Solar Module
• A Solar Cell generated voltage is 0.8 V.
• A number of solar cell connected in
series make, MODULE

13. SOLAR PV-ARRAY

14. Problem with PV MODULE

15. Types of SOLAR MODULE
MONOCRYSTALLINE (Single Silicon )
• It have only single crystal
per cell
• efficiency of this panel is
20 – 25(in %)

16. POLYCRYSTALLINE (Multi Silicon)
• It have configured with
multiple atoms of silicon
• Efficiency of this panel is
10 – 15(in %)

17. AMORPHOUS
• It is made by thin film of silicon
material.
• It’s efficiency is very
low 5 – 6(in %)
• It doesn’t have any crystalline.
