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

Thiruvallur, Tamil Nadu

It has a relatively small proportion of its net sown area unirrigated, indicating poor irrigation demand. The average monthly per capita expenditure of rural agricultural households is relatively high for the district, suggesting higher purchasing capacity of the farmers here. The district has a relatively high penetration of banks in rural and semi-rural areas, facilitating higher access to institutional credit for farmers. There is a comparatively high level of farm mechanization in the district, implying a positive outlook towards progressive technologies amongst the farmers. The district has a relatively high proportion of small and marginal farmers. The district appears in the group of districts, which show (very) low vulnerability 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 Limited Suitability

Individually owned off-grid solar pumps

Limited Suitability

The district has a comparatively high concentration of diesel pump users, high crop revenue per holding, and a relatively high disbursement of institutional credit. However, groundwater availability is below the safe limit. Water conservation and efficient irrigation practices (such as drip irrigation) should be promoted to improve the viability of solar pumps.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 22,718 57
Water Availability Index 0.44 33
Crop revenue per holding (INR) 86,657 52
Medium and long term institutional credit disbursed in a year (in INR Crore) 92.2 67

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 89% 99

Solar based water as a service

Not Suitable

The concentration of small and marginal farmers is rather high in the district, but groundwater availability is below the safe limit. In addition, a relatively low proportion of unirrigated area makes it very difficult to promote solar-based irrigation through the water-as-a-service model here, unless it undercuts the price of water from existing sources, and improves water utilisation through promotion of micro-irrigation.

Parameter Value Percentile
Water Availability Index 0.44 33
Proportion of small and marginal cultivators 95% 80
Unirrigated net sown area as a share of total net sown area 9% 12

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has a relatively high proportion of gross cropped area under horticulture crops, a high concentration of marginal farmers and a comparatively high disbursement of institutional credit to marginal farmers, but groundwater availability is below the safe limit. Water conservation and efficient irrigation practices (such as drip irrigation) should be promoted to improve the viability of small capacity pumps.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 11% 64
Water Availability Index 0.44 33
Proportion of marginal cultivators 84% 83
Medium and long term institutional credit disbursed in a year (in INR Crore) 92.2 67
