Solar Thermal Manufacturer · Since 2006
Rudra Solar Energy engineers and manufactures solar dryers, cookers, ovens and desalination systems that cut fuel bills, protect harvests and run on nothing but sunlight.
Trusted by organisations across India
What we build
From dehydrating a tomato harvest to distilling clean drinking water, every Rudra system runs on free solar heat.
Research-led engineering
As a reputed solar-thermal OEM, we engineer far more than we assemble. An in-house automated test facility and active university research partnerships drive continuous improvement across every dryer, cooker, oven and desalination system — patented engineering that lakhs of customers, from smallholder farmers to large corporates, already rely on.
Who we serve
FPOs and cooperatives use our solar dryers to add value to raw produce, cut post-harvest losses and earn more per kilogram of crop.
Commercial processors dehydrate fruit, vegetables, herbs and spices at scale without the recurring cost of LPG, diesel or grid power.
Hygienic, dust-free solar drying preserves colour, aroma and oil content to meet export-grade quality standards.
Low-cost, easy-to-operate dryers let rural SHGs and women-led micro-enterprises build profitable dried-food businesses.
Schools, ashrams, temples and hostels cook midday meals with solar cookers and community ovens, slashing fuel budgets.
Development agencies deploy our systems across livelihood, nutrition and clean-energy schemes with proven field reliability.
Why choose us
Plenty of suppliers will sell you a solar product. Far fewer design it, build it, install it, and still answer the phone three years later. Here is what actually sets us apart.
We are the manufacturer, not a reseller. Every solar dryer, cooker, oven and desalination unit leaves our own workshop — so we control the steel, the glazing, the trays and the price. When your crop or your rooftop needs something different, we change the drawing, not the excuse.
Our team brings years of solar-thermal engineering experience, proven in real Indian conditions — dusty yards, monsoon humidity, high-altitude cold. That hard-won expertise shapes how we size and build today. You can see it in our success stories and across the regions we serve, from Gujarat to Ladakh and the North-East.
And we stay involved after the sale — we install, we train your team, and we service what we build, nationwide. Tell us your crop, capacity and location and you will have an honest recommendation within one working day. Request a free quote or talk to our engineers.

Proof in the field
Farmer Producer Organization
A Himachal apple FPO cut post-harvest losses and created a premium dried-apple product line using Rudra solar dryers.
NGO / Development
In a high-altitude region with abundant sun and harsh winters, solar dryers let communities preserve apricots and vegetables for the long off-season.
Clean Energy / Livelihoods
A livelihood program paired Rudra solar dryers with rural entrepreneurs to dry spices and produce to market-grade quality.
Nationwide reach
We supply, install and support solar systems right across India — including high-altitude Ladakh, the hill states and the North-East. Tap any state to see how solar drying and cooking work there.

What our clients say
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.
Hygienic, dust-free drying changed how buyers see our spice lots. Rejections dropped and we finally hit export-grade moisture levels consistently, batch after batch.
The community solar cooker feeds 200 children every afternoon at our hostel. Zero gas bills, and the meal is ready on time — rain or shine.
Rudra sized a 50 kg dryer exactly to our mango-pulp volumes. Their engineers commissioned it on site and trained our women’s group themselves — nothing was left to guesswork.
In Ladakh the cold and the altitude defeat most equipment. Their dryer kept working right through the season and our apricots now grade as premium.
The solar baking oven cut our bakery’s fuel cost dramatically. The even-bake quality genuinely surprised us — a better crust than the LPG oven it replaced.
We deployed Rudra dryers across six SHG clusters. Their after-sales support is genuinely responsive — a call gets answered, not ignored.
Clean drinking water from their solar still has been a quiet game-changer for our remote field station. Low maintenance and no running cost at all.
Honest sizing advice. They told us a smaller unit would do the job rather than overselling — that earned our trust, and our repeat orders.
From enquiry to installation in under three weeks. The 25 kg dryer runs daily for our amla and ginger-candy line without a hitch.
