·         SoLAR-Phase II will be implemented in partnership with government and implementing agencies responsible for solar agriculture policies and programs and runs from July 2025 to December 2028.

·         By July 2025, the Pradhan Mantri Kisan Urja Suraksha evamUtthaan Mahabhiyan (PM-KUSUM) scheme  had solarised irrigation pumps for more than 1.43 million farmers, making it the world’s largest programme of its kind.

·         Insights from SoLAR Phase II will guide the post-2027 version of PM-KUSUM, helping make it more groundwater-smart and gender-inclusive.
