Price of solar panels has declined rapidly. Encouraged by increasing affordability of the technology and its promise to curb the demand for subsidised electricity, state governments in India are aggressively promoting solar irrigation pumps. Rajasthan became the pioneer by announcing a scheme in 2011 with 86% subsidy to horticulture farmers who used drip irrigation and farm ponds. Based on extensive fieldwork and survey in three districts of Rajasthan, this paper looks at the farmers' experiences, the design and implementation of the policy, and makes recommendations for a faster and more equitable diffusion of the technology, which could attack India's invidious nexus between energy and groundwater irrigation, and change it for the better.
