The report examines a pilot project in Uttar Pradesh, India, where solar irrigation pumps (SIPs) were used to power grain mills. The study found that this 'secondary use' of solar power reduced milling costs and travel time for rural communities and empowered women and elders. However, the pilot faced operational challenges including poor siting and limited operator availability. The authors argue that integrating secondary uses into government policy and pairing them with battery storage and female operators could maximize the economic returns of solar assets.
