What may the problems posed by renewable
resources?
Nano wire batteries
15. p-n junction
Light can be separated into different wavelengths
Only photon has more energy required can generate electron-hole pair
PV cell working
20. Solar electricity prices are today, around 30 cents/kWh, but still 2-5 times
average Residential electricity tariffs
RENEWABLE ENERGY COSTTRENDS
21. In terms of overall installed PV capacity, India comes fourth after Japan, Germany and U.S.
(With Installed capacity of 110MW)
In the area of Photovoltaics India today is the second largest manufacturer in the world of
PV panels based on crystalline solar cells.
(Industrial production in this area has reached a level of 11 MW per year which is about
10% of the world’s total PVproduction)
A major drive has also been initiated by the Government to export Indian PV products,
systems, technologies and services
(Solar Photovoltaic plant and equipment has been exported to countries in the Middle
East and Africa)
22.
23. Pv growth in india
Solar installed capacity in India is 20006 MW
25. High band gap PV cell provides higher voltage
Typical efficiency of commercial PV is around 12%
Theoretical efficiency of PV cell
26. Types of solar cells
• MONOCRYSTALLINE
• POLYCRYSTALLINE
• THIN FILM
27. Where is the cost:
• Produce wafer (40%)
• Fabricate cell (30%)
• Interconnect and laminate (30%)
•Installation cost (same as cost
of the module)
State, federal, utility and
other subsidize combine
paying half of the cost
Decline price of pv
30. THINFILM
March 30,
2016
Simple Production
Least Cost
High Temperature Have Less impact
Least Efficient (6-10%)
Tend To Degrade Faster
Have Shorter Warranty
33. SOLAR PV MODULE
• MODULE OR PANEL IS COMBINATION
OF DIFFERENT PV CELL CONNECTED
IN SERIES.
• 36, 60, 72 CELLS ARE COMMON
• SINGLE CELL VOLTAGE : 0.5 -0.6 VDC
38. If the PV market growth continues at rate of
20% continues in 50 year, there will be 5 TW
of energy provide by PV cells on the ground
Within 50 years, photovoltaic will supply
more than half of the world’s energy
requirement
