5. Facts about Solar Energy
• Earth surface receives 1.74 x 1017
watts of power
from the sun approximately at any moment.
• India – 5000 trillion KWH per year
• Sun energy is localized energy
• No associated transmission / distribution cost and
consequent associated losses.
• Silent long lasting energy which can be used any
where

6. What is Solar Photo
Voltaic
And how PV works
• Photon of sunlight hits photo voltaic panel
• Electron knocked loose by particle of
sunlight
• Free electron collected by the conductors
• DC electricity is produced
• Inverter converts DC electricity to AC

(national average)

15. Constraints with the non renewable
 Raw material availability and quality
 Power plant location dependent (near to raw material to bring cost of
economy)
 Continuous supply of raw material for efficient power plant
 Centralized source of power and requires huge land
 Huge transmission and maintenance cost
 Dangerous Environmental effect
 20% to 35% expansion of global energy demand over the next 15 years

OFF-GRID
CONNECTED
Generated energy injected into utility Grid
Generated energy is used on site

23. Type of Metering
Gross
Metering
Net
Metering
Generated Solar electricity is fed back
directly into the grid And incentives based
on feed-in tariffs proportional to the
energy fed back to the grid is received.
the excess generated solar electricity is
send back to the grid.
