5. The opportunity
• India has 130,000 GW of installed pumping
capacity in the form of electric and diesel
tube wells
• Sustainable solar irrigation pumps with
feed-in tariff for selling excess electricity to
the grid
Triple wins
• Reduction in greenhouse gas emissions
• Sustainable use of groundwater
• Higher incomes for farmers
India: smart solar irrigation
The result
• Launch of the world’s first Solar Pump Irrigation
