Why Solar Photovoltaic..?? • The 89 petawatts (89 x 10 15) radiation of THE SUN reaching on the Earth

surface plentiful almost 6000 times more than 15 terawatts(15 x 1012) of average electric power consumed by humans Globally/Day.

• Solar Power has the highest power density (global mean of 170 W/m2) among renewable energies.

• PV installation can operate for many years with little maintenance.

• Solar electric generation is economically superior where grid connection or fuel transport is difficult, costly or impossible.

• Long-standing examples include satellites, island communities, remote locations and ocean vessels.

Solar Photovoltaic

• Solar Photovoltaic (PV) is the technology of Solar cells for energy by converting Solar energy (sunlight, including

• UV rays) directly into electricity by Photovoltaic effect.

Photovoltaic effect

• It refers to photons of light knocking electrons into a higher state of energy to create electricity.

Working of Solar Photovoltaic Cell

• When solar panels are placed in the sunlight , photons will strike the surface and emits electrons.

• As a result electron hole pair is created in the solar cell.• When external circuit is connected to the solar cell, electrons flow in

the circuit and the current is generated.

1 KW Solar Photovoltaic System

• This 1 kilowatt system would make 1 kilowatt-hour of electricity for every hour it is in the sun.

• In North Gujarat we have an average of 6.5 good sun hours every day (more in the summer when the days are longer, less in the winter when the days are shorter).

• Remember weather data, and any losses for inefficiencies, wiring, inverter losses affect to the Efficiency of the PV System around 20-35 % .

• A Photovoltaic Panel is perform at about 11-15 % efficiency.

• The Area required for the 1KW PV System is ~7 m2.

Estimated Power produce by PV System

Parameters DATA Collected

Average Sun Hours years ( North Gujarat ) 6.5 hours

Efficiency of System 80%

Power Produce 1kW PV System per day (ŋ=0.8) 1kW x 6.5 hr x 0.8 = 5.2 kWh or units

Power Produce 1kW PV System per month (ŋ=0.8) 5.2 kWh x 30 = 156 kWh or units
