• In RAJASTHAN solar radiation is high about 6.2 – 6.4 kWh(m2)daily.

• Solar radiation is important for photovoltaic energy

Solar EnergySolar energy Originates with the thermonuclear fusion reaction

occurring in the sun.

• The sun delivers its energy in two main forms: heat and light

This Solar Radiation create two types of effects normally

Photoelectric Effect

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.

Solar Module

• A Solar Cell generated voltage is 0.8 V.

• A number of solar cell connected in series make, MODULE

SOLAR PV-ARRAY

Problem with PV MODULE

Types of SOLAR MODULE

MONOCRYSTALLINE (Single Silicon )

• It have only single crystal

per cell

• efficiency of this panel is

20 – 25(in %)

POLYCRYSTALLINE (Multi Silicon)

• It have configured with

multiple atoms of silicon

• Efficiency of this panel is

10 – 15(in %)

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.
