4. RURAL POLPULATION SCENARIO IN INDIA (2019)
Total Population = 136.6 crores
TOTAL Population 136.6 Crores
Rural 65.97 % (90.11 Crores)
Dependent on Agril 70 % (95.6 Crores)
No. of Farm Families 18 Crores
Rural Households 21.265 Crores
Agril Labor 15 Crores
Work Force 50 % ( 68.3 Crores)

5. Average land
holdings / household
1.08 ha
Annual Income Rs77112/ -
Expenditure / ha Rs83683/-
Indian Farmer’s Income &
Expenditure
Expenditure is more than Income

6. FARMERS LAND HOLDINGS CATEGORY IN
INDIA
1 Marginal - below 1.00 hectare
2 Small - 1.00-2.00 hectare
3- Semi- medium— 2.00 - 4.00 hectar
4 Medium farmer— 4.00 -1 0.00 hectare
5. Large farmer - 10.00 hectare and above
% Land Holdings
Small and Marginal = 82 %
Semi-medium and medium = 13.2%
Medium Farmers = 3.8 %
Large = Less than 1 %

7. Indian Farmer’s contribution
World Largest producer of milk, pulses
and jute,
World second largest producer of rice,
wheat, sugarcane, groundnut,
vegetables, fruit and cotton.
World leading producer of spices,
fish, poultry, livestock and plantation
crops

8. Operational Power Availability on Indian Farms
(Million KW) and % of Electric Power
Human 13.6
Animal 19.76
Mechanical 186.5
Electrical 62.9 (23 % of Total)
Average 2.02 kW / ha

9. ELECTRICAL ENERGY IN INDIA
Per Capita elect Consumption = 1181 kWh
Elect Energy in Agril = 23 % of total produce
Growth in Elect Use on Farm = 5.6 % / year
Electric consumption in agril = 208 GkWh

10. NATIONAL SOLAR MISSION TARGET SET
Setting Solar Panels
2010 – 13 = 7 million sq m
2013 – 17 = 15 million sq m
2017 – 22 = 20 million sq m
Waste lands available to set up solar plants =
32,000 sq km
Available waste lands can produce = 2000 GkWh
Daily solar power potential = 0.25 kWh / sq m

11. Comparative cost of solar and diesel power
Cost of Solar Power = Rs 4 to 5 per unit kWh
Cost of Diesel Power = Rs17 per kWh

12. Solar Energy Potential in India
Average solar Radiation = 4.5 to 6.6 kWh / sq m /
day (5.55 kWh)
Annual sun shine hours = 2600 to 3200 (2900
Hours)
Average Solar Radiation = 200 MW per sq km
Total Geographical Area = 3.287 million sq km
Total Solar Energy Available = 657. 4 million Mega
Watt
Or
13750 kWh /sq m / year
Total Arable Land = 159.7 million ha
Elect Power Required for Arable land = 471.115
million kW

13. LAND AREA for 1 MW Solar Power
For Solar panels = one ha / 2, 5 Acres
For Solar Panels and other Accessories = 1.62 ha (4 acres)
1 kW PV plant Generates 3 to 4.5 kWh / day or 100 – 1600
kWh / year
1 kW solar Panel
4 Panels of 250 Watt or 3 Panels o 350 Watt
3.1 % (32,000 sq km) of land unsuitable for agriculture can
generate 3400 TWh / year from solar

14. STEPS TO DESIGN FARM SOLAR POWER UNIT
Say Power Required = 3.5 KW
Power generation / Panel = 230 to 270 Watt
Number of Panels = 12 or 14
Size of Panel = 1.6 x 1 m
Number of cells / Panel = 32
Voltage generated = 14.72 volt
Cost of monocrystalline panel = Rs 47 / Watt

15. ON - GRID COST OF SOLAR PUMPS WITH INSTALLATION
With Solar Panels, On – Grid Solar Inverter, connectors,
structure, junction box, AcC Cable 20m. DC cable 30m,
accessories
MNRE subsidy 90 % for Farmers only
• 90% On Solar Water Pumping System for farmers only.
• 70% For 3 hill states i.e. Himachal Pradesh, Uttarakhand &
Jammu-Kashmir only.
Power (kW) Cost (Rs) Subsidy
(Rs)
Farmer’s
Share (Rs)
1 84,000 75,600 8,400

3 2,15,000 1,93,500 21,500
5 2,85,000 2,56,500 28,500

16. 70 % Subsidy on other agricultural appliances
is also allowed on the basis of Benchmarked
Installation cost which is Rs50 per Watt
