Prince India dish 2009

Promoters and Researchers In Non-Conventional Energy (PRINCE) is a volunteer-based group dedicated to creating a better world for everyone through the use of renewable energy. We believe that protecting and enhancing the environment is possible only through using non-conventional energy sources. We are based in Dhule, Maharashtra, India and work in association with the local NGO Jankibai Trust.


  • July 2011 - June 2012: International opportunity for testing solar cooker designs - Originally announced as a one-time event Oct. 11-13, 2011 with a related conference, the solar cooker competition has been cancelled, and instead there will be a year-long opportunity for having solar cookers and fuel stoves tested free. India’s Promoters and Researchers in Non-Conventional Energy (PRINCE) group has updated standards for solar cookers, developed in conjunction with input from SCWNet members. These universal testing standards will be used to evaluate the cookers by simulating real world conditions. Designers, manufacturers, NGOs and individuals are invited to submit solar cookers for testing, and need not be present for the tests. While there will be no cash prizes, solar cookers will be rated on thermal performance, cost of manufacture and transport, and user convenience. Send cookers anytime between now and June 2012 to: Prof. Ajay Chandak, PRINCE, Shamgiri, Opp Swagat Lodge, Agra Road, Deopur, Dhuli – 424005, Maharashtra, India. Include your usual instructions for consumers. If you wish your cooker returned, please arrange to cover return shipping costs. After testing, entrants will be contacted with results, and have the option of omitting their information in the publicly listed ratings. No reply from entrants within two weeks or so after receiving their results will be taken as consent to publish. Other questions? Email:

Recent news and developments

  • December 2011: We are getting amazing feedbacks from end users for installations carried out for the PRINCE-40 solar community cookers, with the help of NGOs like WOTR and MPSSS. It looks like these organizations will expand the program and we should see few hundred systems in schools in next year. You will find a few more models of community solar cookers from us in coming year.
  • October 2011: The latest PRINCE newsletter announces a scheduled training for Scheffler Reflector Solar Cookers coming January 21 -27, 2012. Next, PRINCE founder Ajay Chandak has received an Energy Conservation Award from the Government of Maharashtra. Also, PRINCE has organized a networking workshop for all stakeholders in the renewable energy business on January 25 - 26, 2012. PRINCE Biogas Plants now approved by MNRE.

Solar Canteen in India

Ajay Chandak and volunteers running solar canteen.

  • March 2009: Energy Day was celebrated in a unique way in city of Dhule, India, by a voluntary organization PRINCE (Promoters & Researchers In Non Conventional Energy). With the help of around 100 students of mechanical engineering from SSVPS BSD College of Engineering a solar canteen was set up by Prof. Ajay Chandak, Prof. Sham Patil and Prof. Deepak Dubey. Three SK-14, solar dish cooker, one square PRINCE design of dish cooker and one Community solar cooker of 2.3 m dia. were used in the canteen. On these gadgets almost 1000 snacks were cooked and sold by the students. Staff and students of the Institute and invited guests from the city enjoyed solar food. Guests had fun watching the food being cooked in front of their eyes in the solar cookers and to taste the same as any other methods of cooking. Snacks cooked and sold on large scale were Idlis and coffee. However other snacks like Khichadi, Cakes etc. were also prepared for demonstration to the visitors. Many students, staff and visitors showed great interest in the solar cooking demonstrations and local manufacturer, M/s Essential Equipments, reported sell of around ten solar cookers in next two days, which is welcome outcome of such event. Many students were thrilled with the experience of this event for the first time in their life and have shown great interest to organize such events at different locations in the city, next year. Principal of the Institute Dr. Jahagirdar has promised to support such events in future. Other programs for energy day celebrations included demonstrations of energy efficient technologies for lighting, fans and domestic appliances. All these equipments were demonstrated to visitors. Many visitors reported having changed their copper and aluminum ballasts with electronic ballasts in next week. After all seeing is believing. One workshop was also organized for local masons, hoteliers and interested people to teach them skills of installation of biogas plants working on food waste. Chairperson of PRINCE, Prof. Ajay Chandak, has given up LPG since last four years and fuel requirement for his family comes up from the solar cookers and biogas plant working on food waste. PRINCE group has come up with a special cost effective design of biogas plant. After the workshop five people have shown interest in installation of the biogas plants.
Prince India July 2007
  • November 2007: Professor Ajay Chandak, of PRINCE, reports completion of an ambitious project to manufacture, transport, install and commission over 300 large parabolic solar cookers at tribal schools in the Indian state of Maharashtra. The project was coordinated by Chandak, with manufacturing by PRINCE trainees M/s Essential Equipments and three contractual manufacturers. Twenty-five trained teams carried out installation and testing of the cookers. The entire process took just 45 days, and resulted in 100 schools being equipped. The "community solar cookers," as Chandak refers to them, are 2.3 meters in diameter and powerful enough for a 22-liter pressure cooker. Each cooker cost around Rs. 26,000 ($650) and comes with a large pressure cooker and other accessories.
