Karur, Tamil Nadu | Solar Pumps Tool Made with Humane Club

Karur, Tamil Nadu

In the district, horticulture crops occupy a relatively high proportion of gross cropped area, raising the economic viability of solar pumps here. Overall, the water availability for irrigation in the district (based on ground water development and long-term trends of water level decline) is critical since the resource is overexploited, jeopardizing the long-term sustainability of solar pumps. The average monthly per capita expenditure of rural agricultural households is relatively high for the district, suggesting higher purchasing capacity of the farmers here. There is a comparatively high level of farm mechanization in the district, implying a positive outlook towards progressive technologies amongst the farmers. The district appears in the group of districts, which are (very) highly vulnerable towards climate change, as per an index constructed by CRIDA.

Deployment Approaches

Approaches Feasibility
Individually owned off-grid solar pumps Limited Suitability
Solarisation of feeders Limited Suitability
Solar based water as a service Not Suitable
Promote 1 HP and sub-HP pumps Not Suitable

Individually owned off-grid solar pumps

Limited Suitability

The district has a relatively high disbursement of institutional credit and a comparatively high concentration of diesel pump users. However, ground water availability is below the safe limit, and crop revenue per holding is low, making it very difficult to promote the private ownership of solar pumps here.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 30,457 63
Water Availability Index 0.18 14
Crop revenue per holding (INR) 73,608 46
Medium and long term institutional credit disbursed in a year (in INR Crore) 34.9 53

Solarisation of feeders

Limited Suitability

The district has a relatively high penetration of electric pumps, and its DISCOM has a rather high bulk power purchase rate, but the district has a comparatively low extent of feeder segregation. Solarisation of the feeders will only be possible once the district separates agricultural feeders from the rest.

Parameter Value Percentile
Power purchase rate for DISCOM (INR/kWh) 3.68 26
Extent of feeder segregation 0% 0
Proportion of cultivators reporting use of electric pumps 35% 82

Solar based water as a service

Not Suitable

The district has a rather low concentration of small and marginal farmers and a relatively low proportion of unirrigated area. Moreover, groundwater availability is below the safe limit, making it extremely difficult to promote solar-based irrigation through the water-as-a-service model here.

Parameter Value Percentile
Water Availability Index 0.18 14
Proportion of small and marginal cultivators 81% 40
Unirrigated net sown area as a share of total net sown area 44% 36

Promote 1 HP and sub-HP pumps

Not Suitable

The district has a relatively high proportion of horticulture crops under gross cropped area. But, a rather low concentration of marginal farmers, a comparatively low disbursement of institutional credit to them, and groundwater availability below the safe limit make it extremely difficult to promote 1 HP and sub-HP pumps here.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 34% 90
Water Availability Index 0.18 14
Proportion of marginal cultivators 63% 48
Medium and long term institutional credit disbursed in a year (in INR Crore) 34.9 53

Leveraging Solar Pumps to Promote Policy Objectives

If you are deploying solar pumps in this district then you can further these policy objectives.

Per Drop More Crop

In the district, crops suitable for drip and sprinkler irrigation occupy a relatively high proportion of gross cropped area, making it easy to adopt such high precision irrigation methods. Solar pumps, along with other efficient and precise water application devices, could be deployed under Per Drop More Crop to promote efficient irrigation.

Parameter Value Percentile
Area under crops suitable for drip and sprinkler irrigation as a share of total cropped area 49% 85
