It has a relatively small proportion of its net sown area unirrigated, indicating poor irrigation demand. Horticulture crops occupy a relatively low proportion of gross cropped area in the district, diminishing the economic viability of solar pumps here. Overall, water availability for irrigation in the district (based on ground water development and long-term trends of water level decline) is within the safe limit, enhancing long-term sustainability of solar pumps. The average monthly per capita expenditure of rural agricultural households is relatively low for the district, suggesting poor purchasing capacity of the farmers here. It has a relatively low penetration of banks in rural and semi-rural areas, impeding 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.

Deployment Approaches

Individually owned off-grid solar pumps

Limited Suitability

The district has ground water available within the safe limit, a comparatively high concentration of diesel pump users, and a relatively high disbursement of institutional credit, but low crop revenue per holding. Greater support, either through subsidies or credit, would be required to enable farmers to adopt solar pumps.

Solarisation of feeders

Suitable

Given the relatively high cost of power supply for the respective DISCOM, a comparatively high extent of feeder segregation, and a high penetration of electric pumps, solarisation of the feeders would be a recommended way to promote solar-powered irrigation in the district. It would ensure the rapid and cost effective solarisation of irrigation power at a large scale.

Solar based water as a service

Limited Suitability

Groundwater availability in the district is within safe limit and the concentration of small and marginal farmers is comparatively high, but the proportion of unirrigated area is relatively low. A solar-based water service will have to compete with existing sources of irrigation.

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has groundwater availability within safe limit, a rather high concentration of marginal farmers, and a comparatively high disbursement of institutional credit to marginal farmers, but the proportion gross cropped area under horticulture crops is relatively low. Farmers should be incentivised to grow horticulture crops based on the agro-economic suitability of the region and market linkages to improve their revenue, making small sized pumps viable, by improving their capacity utilisation.

Solarisation of individual grid-connected pumps

Suitable

Given the relatively high rate of power subsidy for agriculture consumers, a comparatively high extent of feeder segregation, ground water available within the safe limits and a high penetration of electric pumps, solarisation of individual grid-connected pumps would be a recommended way to promote solar-powered irrigation in the district. It would ensure the rapid and cost effective solarisation of irrigation power at a large scale.

Leveraging Solar Pumps to Promote Policy Objectives

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

Doubling Farmers’ Income – Capital Investment

Given the high concentration of small and marginal farmers, and their relatively better access to institutional credit, the district is suitable for doubling farmers’ income through capital investment. Solar pumps could be one of the farm technologies to invest in for farmers, especially 1 HP or sub-HP pumps for marginal farmers.

Doubling Farmers’ Income – Crop Diversification

In the district, horticulture crops occupy a relatively low proportion of gross cropped area, indicating an opportunity for growing more high value non-staple crops. Solar-powered irrigation could be an alternative source of reliable irrigation, making it easier to achieve crop diversification and enhance farmers’ incomes.

National Mission on Oilseeds and Oil Palm (NMOOP)

The relatively low share of oilseeds and oil palm crops under gross sown area in the district makes it a suitable candidate for promoting NMOOP. Solar pumps could meet irrigation needs for these crops and help farmers diversify their yields beyond cereals.
