The quality of solar infrastructure determines the success of India's agro-energy sector

For farmers, a reliable solar irrigation pump makes it possible to significantly reduce diesel fuel expenses, which reach about ₹6,790 per acre when growing wheat and even more for cotton. A smoothly operating solar setup is capable of saving from ₹5,000 to ₹6,500 annually. In Haryana, farmers utilizing well-designed solar systems of an appropriate size report savings of up to ₹55,000 per year.

The first phase of the PM-KUSUM scheme has enabled the installation of over 1.15 million standalone pumps, and its timeline has been extended until March 2027. The next step will be PM-KUSUM 2.0 with a budget of over ₹50,000 crore, which includes a 10 GW agrivoltaics component combining energy generation and crop cultivation on the same land. Farmers' incomes under this model are expected to grow from approximately ₹60,000 to over ₹100,000 per acre due to the combination of revenues from the harvest and electricity sales.

Agrivoltaics structures require load calculations: due to the passage of tractors and combine harvesters, the clearance must be four to five meters, at which wind loads and requirements for steel, piles, and foundations differ significantly from ground-mounted systems. Pump controllers and associated electronics remain the most vulnerable elements. Modern developments apply fuzzy logic and sensorless tracking to manage current and torque.

Pumps built to the IS17018 standard must withstand groundwater corrosion for a minimum of five years. Regulators are tightening requirements: in August, the MNRE issued a draft policy to tighten controller standards, and starting from June of the current year, all new KUSUM projects are required to use modules based on domestic certified cells. Equipment must be designed to withstand real farm conditions for 25 years.
