We dry turmeric and chilli for 400 member farmers now without ever watching the sky. The tunnel dryer paid for itself in one season, and the colour we retain has lifted our market price.
About Us
Engineering the sun into clean, useful heat
Founded in 2006, Rudra Solar Energy Private Limited designs and manufactures solar-thermal systems that lower costs and protect harvests across India.
Trusted by organisations across India
Founded in 2006 by visionary social entrepreneur Mr. Devang Joshi, Rudra Solar Energy Private Limited was built on one conviction — that decentralised solar-thermal technology can serve society while protecting the planet. Today we are one of India's most reputed and trusted solar-thermal brands and Original Equipment Manufacturers (OEM), engineering clean, useful heat for everyone from the smallholder farmer to the largest corporate.
Research and development at our core
We are engineers first. Continuously engaged in research and product improvisation, we run an in-house, high-tech automated test facility for solar-thermal equipment — where every design is measured, refined and proven before it ever reaches the field. That work is strengthened by active associations with leading state and central universities and a network of research scholars, keeping our engineering at the frontier of solar-thermal science.
Patented, proprietary engineering
Our systems are born in our own laboratories, not assembled from off-the-shelf parts. Backed by patented, proprietary designs, every Rudra solar-thermal system reflects years of original engineering — the reason our quality, efficiency and durability are so difficult to match.
A complete solar-thermal range
Solar cookers, solar dryers, solar ovens and solar desalination systems — plus a wide range of specially developed products and applications, purpose-built for the full spectrum of users, from the bottom of the pyramid to major corporates and institutions.
Application engineering that solves real problems
Across our journey we have focused deeply on application engineering — studying how solar heat is genuinely used and translating that insight into practical, field-ready products. That discipline has produced a versatile, dependable product range now trusted by lakhs of customers across India, powering a cleaner and greener future.

More about Rudra Solar Energy
Rudra Solar Energy Private Limited was founded in 2006 and is based in Ahmedabad, Gujarat, India. The company designs and manufactures solar-thermal systems, including solar dryers, solar cookers, solar ovens and solar desalination systems, for individual users, farmers, entrepreneurs, institutions and commercial processing requirements across India. As an Indian solar dryer manufacturer with long-standing solar-thermal engineering experience, Rudra develops application-specific systems in multiple capacities and supports customers from system selection to installation and after-sales service.
Rudra Solar Energy is an in-house solar-thermal manufacturer and OEM, not simply a reseller. The company designs, engineers and manufactures its solar dryers, solar cookers, solar ovens and solar desalination systems through its own engineering and manufacturing setup in Gujarat. In-house product development, testing and fabrication give Rudra greater control over system design, materials, quality, capacity selection and application-specific customisation. This also enables the company to develop solar dryer solutions for individual users, farmers, entrepreneurs, SHGs, FPOs and commercial food-processing requirements rather than depending only on standard third-party products.
Rudra Solar Energy serves agriculture, horticulture, food processing, spice and herb processing, grain and seed handling, institutional, research and other solar-thermal application sectors across India. Its solar drying solutions are used for suitable fruits, vegetables, spices, herbs, grains, pulses, oilseeds, seeds, medicinal plants and other agricultural or food products, depending on the application.
Rudra works with individual users, farmers, women entrepreneurs, SHGs, FPOs, food processors, MSMEs, exporters, NGOs, research institutions, government organisations and commercial processing units. With multiple solar dryer capacities and application-specific configurations, the company can support requirements ranging from small-batch and farm-level processing to larger commercial and institutional projects.
Yes. Rudra Solar Energy designs and manufactures custom and hybrid solar dryer configurations in-house for specific crops, processing capacities, site conditions and operating requirements. Solutions can be engineered from compact small-batch systems to larger commercial and industrial-scale solar drying applications, depending on the fresh-input quantity, commodity, required batch capacity, available space and intended end product.
Because Rudra handles engineering and manufacturing in-house, the team can recommend an appropriate dryer configuration rather than limiting customers to a single standard model. Hybrid options can also be considered where the application requires additional drying support beyond solar energy alone. To receive a suitable recommendation, share your crop or product, fresh-input quantity per batch, location and processing requirement with Rudra Solar Energy.
Rudra Solar Energy solar dryers are designed for long-term outdoor use, but their actual service life depends on the selected model, construction materials, operating environment, usage and maintenance. Depending on the configuration, Rudra solar dryers use durable structural materials, food-contact trays and UV-stabilised polycarbonate or toughened-glass glazing options intended for regular solar drying applications.
Routine care such as cleaning trays and the drying chamber, keeping glazing and airflow paths clean, and periodically checking fans, fasteners and other operating components helps maintain reliable performance over time. Customers should select the dryer according to the application and site conditions and confirm model-specific construction, maintenance and warranty details before purchase.
You can explore real Rudra Solar Energy solar dryer installations through our Success Stories, Installation Gallery and Locations pages. These resources showcase field applications involving farmers, women entrepreneurs, SHGs, food processors, research users and commercial operations working with crops and products such as chilli, turmeric, fruits, vegetables, herbs, grains and other suitable commodities.
The Success Stories section documents selected real-world applications and user experiences, while the Installation Gallery provides field photographs of Rudra systems and the Locations section shows the regions where Rudra Solar Energy serves and supports customers across India. Because every installation is application- and capacity-specific, these examples can also help prospective buyers understand how solar dryers are used from small-batch and farm-level processing to larger commercial requirements.
