Basic Introduction to solar PV System.

  1. 1. INTRODUCTION  Renewable Energy or Non-Renewable Energy? OR
  2. 2. Why Renewable Energy?
  3. 3. Why only Solar?  Sun…the never ending source of energy.  Primary source – Fossil Fuels Limited.  Clean Energy.  Easily Scalable.  Modular character technology.
  4. 4. Why only Solar? • The Solar energy radiate by the sun is 3.8 x 1026 joules /sec (NASA). • India is one of the sun’s most favored nations, blessed with about 5,000 Terawh of solar Energy radiation very year with most parts receiving 4 – 7 Kwh / Sq. Meter / Per day. • Daily average solar energy incident over India varies 4 to 7 Kwh/m2 / Day • With about 300 clear , sunny days in a year, India have abundant solar potential.
  5. 5. Photovoltaic Cell  Solar Cell  Working  Material  Type
  6. 6. Fundamental of solar cell. • The μp is the heart of the processing within a computer.. • Similarly a solar cell is the key component in chain of the photovoltaic solar system. • Photovoltaic = photo + voltaic. • Photo associated with light and voltaic means voltage or voltage that developed within the solar cell.

  8. 8. Light And Photo Electric Effect • Photoelectric effect is a phenomenon in which electrons are emitted from matter after absorption of energy from visible light. • Electrons gain energy from incoming photons and are emitted when this absorbed energy exceeds the work function of the material. • Electric field associated with a semiconductor P--‐N junction can form an electric current and deliver power to an external load. • Thus a specially built semiconductor junction can function as a SOLAR CELL converting natural sunlight into electricity.
  9. 9. Photovoltaic Cell Material • Thin wafers of silicon  Similar to computer chips  Much bigger  Much cheaper • Silicon is abundant (sand)  Non-toxic  Safe
  10. 10. PV Technology Classification Silicon Crystalline Technology Mono crystalline PV cell Multi/Poly crystalline PV cell. Thin Film Technology Amorphous Silicon PV cells. Poly Crystalline PV Cells
  11. 11. PV Technology Classification • Silicon Crystalline Technology  Currently makes up 86% of PV market  Very stable with module efficiencies 10-16%
  12. 12. Silicon Crystalline Technology • Mono crystalline PV cell  Made using saw-cut from single cylindrical crystal of Si  Most efficient commercially available module (11% - 18%)  Most expensive to produce Circular (square-round) cell creates wasted space on module
  13. 13. Silicon Crystalline Technology • Multi/Poly crystalline PV cell.  Caste from ingot of melted and recrystallised silicon.  Cells slightly less efficient than a mono crystalline (10% - 16%).  Less expensive to make than mono-crystalline modules.  Square shape cells fit into module efficiently using the entire space.  Accounts for 90% of crystalline Si market .
  14. 14. Thin Film Technology  Silicon deposited in a continuous on a base material such as glass, metal or polymers  Thin-film crystalline solar cell consists of layers about 10μm thick compared with 200-300μm layers for crystalline silicon cells  PROS • Low cost substrate and fabrication process  CONS • Not very stable
  15. 15. Thin Film Technology • AMORPHOUS SILICON PV CELLS. Most inexpensive technology to produce Metal grid replaced with transparent oxides Can be deposited on flexible substrates, less susceptible to shading problems Better performance in low light conditions that with crystalline modules. Operating efficiency ~ 6-8% • PROS  Mature manufacturing technologies available • CONS  Initial 20-40% loss in efficiency
  16. 16. Poly Crystalline PV Cells • Non – silicon based technology • CADMIUM TELLURIDE ( CDTE)  Unlike most other II/IV material cdte exhibits direct band gap of 1.4ev and high absorption coefficient  PROS • 16% laboratory efficiency • 6-9% module efficiency  CONS • Immature manufacturing process
  17. 17. PV Module Technology • PV module mainly available in Mono-crystalline Silicon, Poly-Crystalline Silicon and Thin film.. • PV module Power (Wp) ranges from ~ (1 – 310) Wp • Characteristics:-  Voc ~ Open Circuit Voltage  Isc ~ Short Circuit Current  Vm ~ Voltage at maximum power  Im ~ Current at maximum power  Pm ~ Maximum power • Note ~ While you purchase PV Module must check :-  Measured at Standard Test Conditions(STC): 1KW/m2/day, 25˚C & AM1.5
