From a ₹25,000 Experiment to a ₹14 Crore Business: Varun Raheja’s Solar Revolution for Farmers
India loses a huge amount of fruits and vegetables every year because of post-harvest waste. For farmers, this loss can mean wasted crops, wasted effort, and lost income.
Indore-based engineer Varun Raheja saw this problem differently. Instead of accepting food waste as a part of farming, he began looking for a practical solution using the power of the sun.
While studying Mechanical Engineering at Medicaps University, Varun started experimenting with composting and solar drying. In 2017–18, he built his first small solar dryer on his terrace. He invested around ₹25,000–₹30,000 from his own savings to develop the idea.
What started as a small experiment soon became a business idea.
In 2019, Varun launched Raheja Solar Food Processing Pvt. Ltd. with a simple goal to help farmers convert surplus agricultural produce into products that could be stored and sold instead of being wasted.
The journey was not easy. Many farmers were initially unfamiliar with scientific solar dehydration and did not see post-harvest losses as a major problem. Varun worked with FPOs, NGOs and mentors to create awareness and build trust among farmers.
Today, Raheja Solar operates from a 43,000-square-foot facility in Indore. Its solar drying technology has reached farmers across 26 states, with thousands of dryers installed. The company has also expanded its presence to countries including Kenya, Malawi, Indonesia and Bhutan.
The dryers work using solar energy and are designed to reduce dependence on electricity and chemical preservatives.
The company also operates Bare Fruit, a direct-to-consumer brand that turns surplus fruits into preservative-free snacks.
For farmers using the technology, the company reports income improvements of around 40–50%, by helping them preserve produce and create additional value from crops that might otherwise go to waste.
The business has also seen strong financial growth. Its revenue increased from ₹7.07 crore in FY24 to ₹14 crore in FY25, with the company projecting further growth in FY26.
Varun's entrepreneurial journey also took him to Shark Tank India, where he secured ₹1.75 crore for 7% equity, at a reported valuation of ₹40 crore.
But for Varun, the bigger goal goes beyond revenue.
He aims to empower 5 million farmers by 2030 and build a global movement that reduces food waste while helping small farmers access better markets.
From a ₹25,000 experiment on a terrace to a business working with farmers across India and beyond, Varun Raheja's journey shows how a simple engineering idea can grow into a solution for a much bigger agricultural problem.
This is not just a story about solar dryers.
It is a story about turning wasted crops into new opportunities for farmers.
