India-based Vivasvan Solar has created a collapsible solar structure that can be easily moved within a farm or between farms to efficiently power irrigation pumps. The system consists of photovoltaic panels and variable frequency drives and can be mounted on a trolley.

Rahul Chavan, OPC Director, Vivasvan Industries, said: “In the Sangli region of India, a farm may have two or three sources of irrigation water such as pumped wells, open shafts and artificial ponds. Our mobile systems are equipped with variable frequency The photovoltaic water pumping solution is compatible, giving farmers the flexibility to pump water from different water sources on the farm."

Portable solar systems can develop microscopic cracks during handling, especially in rough fields. To solve this problem, Chavan noted, they installed spring suspensions on the four corners between the panel unit and the trolley platform, and rubber shock-absorbing liners between the solar module frames. These act together as a shock absorber to avoid damage to the panels. In addition, the photovoltaic panels use a mild steel frame developed in-house.

Vivasvan Industries has installed this portable solar structure at a farm in Kharsundi, Sangli district, Maharashtra, India. The entire photovoltaic system consists of 15 Axitec 335 Wp panels. According to Chavan, the system can be customized to provide power ranging from 1 to 7 kilowatts, and is mounted on a trolley.
