Solar insolation in India1. 5 trillion kWh/ year
theoretical potential.Most of the country receives more than 4kWh/m2 /day
2. In most parts of India, clear sunny weather is experienced 250 to 300 days a year.
Rajasthan1. Best solar radiation in India;
Amongst the best in the world2. Solar radiation 6-7 kWh/sq. meter3. More than 325 sunny days in a
year (amongst the best in India)
4
1. Abundantly available at doorstep
2. free of cost
3. Clean energy, pollution free
4. Eco-friendly, Harmonious with nature
5. Ideal for remote areas, where electricity is not available, availability is
capital intensive and diesel is costly/ difficult to get
6. Safe to handle. Devices can be used by layperson without risk
7. Suitable for day time irrigation
8. Uninterrupted supply for 6-8 hours
9. Strong correlation with plant water demand
WHY SOLAR ENERGYWHY SOLAR ENERGY

Rajasthan: Water & Energy the most crucial resources (1)
Renewable Energy in Agriculture sector: the dire need
Irrigation Water
1. Area 10.5% - water resource only 1%
2. One third of the cultivated area under irrigation
3. About 70% area is irrigated by wells & tube wells (ground water) and 27 % by canals
4. Irrigation efficiency (sandy soils) low: 25-35%
5. Rainfall: Erratic, uneven distribution and low (Av. 575 mm)
6. Ground water table going down rapidly and quality of water deteriorating
Conventional Energy
Present generation capacity 9646 MW
Present Agriculture consumption 38%
Long queue for connections
Electricity losses during transmission and distribution extremely high - 30 to 45%
6
Rajasthan: Water & Energy the most crucial resources (2)
RE in Agriculture sector: the dire need
Irrigation Water
Water demand of Agriculture sector: >85%
Dependency on ground water
Canal Irrigation : dependency on neighbouring states
Net Irrigated area 6.4 MH (Micro 1.1 MH)
NW part of state: Adoption of sprinkler-very high
Trend of drip adoption: accelerated
Focus is to increase the irrigation efficiency at farms
Energy for Agriculture sector
Farmers live in remote areas : Electricity access is a challenge
Interrupted supply for irrigation is also a major issue
Availability mostly in rotation: Night time irrigation is a problem for farmer
Heavy subsidy by the state for agriculture supply
A long queue for new connections
Un-interrupted supply and access to remote areas is the focus
7
Rajasthan: Water & Energy the most crucial resources
Solution
Irrigation Water
Efficient techniques of irrigation - drip, mini sprinkler, sprinkler
Rajasthan is the leading state in adoption of sprinkler technique
Drip irrigation is the most efficient technique and is on top priority
Solar programme tied up with drip technology
Use of waste & saline water
Energy for Agriculture sector
Nature’s free gift and environmental friendly –solar energy can access the remotest places
No issue of transmission losses and transmission costs
Uninterrupted supply during the day time
Exploitation of strong co-relation of water requirement of crop and availability of sun light
Potential to use solar energy for waste water / recycled water in agriculture sector
That’s why the state government has made budget announcement to promote both the techniques side by side.

Solar and electric systems Comparison
1. Solar system is simpler and has fewer moving parts as compared to electric connection.
2. Transmission losses negligible3. No chances of electric theft, land losses in lines, accidents & farmers
agitation (law & order) 4. Uninterrupted day time supply & correlated with WR5. Cost - When solar and electric pumps (5HP) are compared in terms of
total life cycle subsidy cost spread over a life span of minimum 25 years, solar pump system is cost effective (Cost: Rs.7.29 lac) as against electric system (Cost Rs.12.24 lac)
25
Solar pumps: benefit over electric systems 1. Govt. investment per ha per year for electric- Rs. 245002. Govt. investment per ha per year for Solar - Rs. 145003. Savings over electric per ha per year - Rs. 10000
Potential coverage• 5000 ha per year, • with 2500 solar pumps, each of 5000 WP
• Investment on subsidy @ Rs. 5.00 lac per pump – Rs. 125 cr• Saving over electricity in 25 year (10000x5000x25) – Rs. 125 cr

Solar and diesel pumps Comparison
1. Solar pumps have higher discharge and head ranges available, as compared to diesel pumps.
2. Solar pump is simpler and has fewer moving parts as compared to diesel pumps.
3. Solar pump requires mostly unskilled labour to run for years together. 4. Total life cycle cost spread over a minimum 20 years - solar pump system
is cost effective – Cost / ha / yr : solar Rs.42000, diesel Rs. 630005. Solar pumps require no fuel transportation and storage.

FeedbackFeedback
Shri Ganganagar 2010-11
1.Solar pump programme undertaken during 2008-09 & 2010-11 implemented and running successfully (Solar Pumps of 3000 Wp already running in tube-wells at farmer fields of Jaipur, Jhunjhunu, Sikar, and Sawaimadhopur)
2.successfully running in low depth wells/ tube wells, and diggies - Bore well depth - 170 to 270 ft.
3.Pump discharge – 5,400 to 10,000 ltr/ hr4.Auto-tracker has increased the efficiency5.All beneficiaries using water saving devices6.Farmers are satisfied – Demand
• from all districts, • for all sources of water, and • for high Wp
37
Conclusions• Water access to un-electrified/
remote areas• Substitute up to 5-7.5 HP electric
connections• Judicious use of irrigation water
through micro irrigation, and integration with Renewable Energy Sources.
• Solar pump is additional award for farmers adopting Hi-Tech cultivation and WHS with drip
• Wide replication will bring costs down within the reach of farmers, with gradual withdrawal of subsidy
• Demand from farmers to extend project in whole state
