This presentation discusses a 1kW solar photovoltaic system. It begins by explaining why solar PV is useful, describing how the photovoltaic effect works to convert sunlight into electricity. It then provides details of a 1kW system, estimating it could produce 5.2 kWh of power per day on average based on the location's sun hours. This equals around 1872 kWh per year, saving approximately Rs. 9,360 annually at current electricity prices. It lists appliances the system could run and the components of a 1kW solar kit, costing Rs. 1,39,000 after discounts.

3. 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.

4. 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.

5. 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.

7. 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.

8. 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
Power Produce 1kW PV System per year (ŋ=0.8) 156 kWh x 12 = 1872 kWh or units
Price of 1 kWh or units ₹ 5
Price per Day ₹ 26
Price per month ₹ 780
Price per Year ₹ 9360
