Quick answer
Rudra Solar Energy supplies affordable solar dryers across Bihar, helping farmers and SHGs cut post-harvest loss by drying vegetables, chilli, makhana and fruit.
Bihar grows some of India\'s most distinctive produce — makhana, litchi, mango, and a steady abundance of vegetables. Much of it is perishable, and far too much is lost between a bumper harvest and a buyer.
Our solar dryers give farmers and small enterprises here a low-cost, fuel-free way to close that gap and hold on to more of what they grow.
Cutting post-harvest loss
Vegetables, chillies, makhana, and fruit like mango and litchi all dry into products with a long shelf life, which matters enormously in a state where storage and cold chains are thin. Drying surplus instead of distress-selling it gives growers both better income and far less waste.
Affordable and easy to adopt
We keep systems simple and affordable, with sizes that suit individual farmers, self-help groups and small processors alike. Training comes with every install, and our team stays reachable so a new user is never left guessing.

Yes. We offer compact, low-cost dryers suited to individual farmers and self-help groups, along with training to get the most from every batch.
