Maharashtra’s Solar Pump Boom Reshapes India’s Farm Irrigation
Solar pumps use sunlight to move water from the ground to farmers’ fields.
They help farmers avoid buying diesel and waiting for electricity at night.
Maharashtra has installed more than 7.47 lakh of these pumps.
Government subsidies make the pumps cheaper for many farmers.
Some farmers say the pumps save money, time and effort.
Because they work during the day, farmers can watch the water and stop it when needed.
However, solar pumps do not automatically protect groundwater.
Researchers found that local water conditions and policies, such as payments for selling extra electricity, affect how much water farmers use.
Farmers also say approvals, equipment quality and repairs can still be difficult.
Maharashtra has installed more than 7.47 lakh solar agricultural pumps and is targeting 10.45 lakh.
The state installed 45,911 solar pumps in 30 days in December 2025, setting a Guinness World Record.
Subsidies under PM-KUSUM and Maharashtra’s MTSKPY scheme have reduced farmers’ upfront costs by as much as 95% in some cases.
Solar pumps provide daytime irrigation without diesel purchases or dependence on unreliable electricity, but farmers report delays, equipment problems and weak maintenance support.
Research shows solar irrigation can reduce water use when incentives reward conservation, but it may not reduce groundwater extraction in areas where water availability is already constrained.
- Who
- Farmers, Maharashtra’s government, the central government and agricultural officials are involved in expanding solar irrigation; researchers and the International Water Management Institute studied its effect on groundwater.
- What
- India is rapidly adopting subsidised solar-powered agricultural pumps, led by Maharashtra, while policymakers address affordability, implementation and groundwater concerns.
- Where
- The rollout is led by Maharashtra and is also occurring across states including Madhya Pradesh, Rajasthan, Uttarakhand, Gujarat, Uttar Pradesh, Kerala, Chhattisgarh and Assam.
- When
- Maharashtra reported its record installation in December 2025; the PM-KUSUM scheme targets 34,800 MW of solar capacity by March 2026.
- Why
- Solar pumps can reduce diesel and electricity expenses and provide reliable daytime irrigation, but their effect on groundwater depends on local aquifers and policy incentives.
Solar Irrigation Benefits
Implementation and Water Risks
Costs and reliability
Solar Irrigation Benefits
Solar pumps eliminate recurring diesel and electricity costs, provide daytime irrigation and reduce dependence on unreliable grid power.
Implementation and Water Risks
Farmers report long approval delays, unclear subsidy information, uncertain pump specifications, substandard equipment and slow repairs.
Groundwater use
Solar Irrigation Benefits
Incentives such as the ability to sell surplus electricity can encourage farmers to use less irrigation water, as observed in Anand, Gujarat.
Implementation and Water Risks
Solar power can make pumping easier and may not reduce extraction where groundwater is already the binding constraint, as observed in Botad, Gujarat.
Access and scale
Solar Irrigation Benefits
Large subsidies and pay-per-use irrigation models are making solar pumps accessible to smallholders and supporting rapid nationwide expansion.
Implementation and Water Risks
Upfront contributions remain significant for some farmers, and unequal subsidies and service quality can limit who benefits from the rollout.
Key facts
- Maharashtra installations
- More than 7.47 lakh solar agricultural pumps installed.
- Maharashtra target
- 10.45 lakh solar pumps.
- Installation record
- 45,911 pumps installed in 30 days in December 2025.
- National scheme
- PM-KUSUM targets 34,800 MW of solar capacity by March 2026.
- Central assistance
- Approximately Rs 34,422 crore under PM-KUSUM.
- Subsidies
- PM-KUSUM subsidies range from 60% to 90%; some Maharashtra farmers received up to 95%.
- Potential savings
- Solar pumps can save Rs 40,000 to Rs 70,000 annually compared with diesel pumps.
- Groundwater finding
- In Anand, Gujarat, solar farmers used up to 608 millimetres less irrigation water than non-solar neighbours; no measurable reduction was found in hard-rock Botad.

Yogeshwari C Chaudhari
Sarpanch of Gram Panchayat Dawwa in Maharashtra’s Gondia district
“Previously, irrigation relied on electricity availability or diesel fuel. Farmers had to bear the associated costs and endure the hardships caused by erratic power supplies.”

“I don’t have to wait for the nights when we get power supply. I can run my pumps using my mobile phone as it’s GPS-connected.”
