Surya Nutan, an indigenous indoor solar cooking system design, developed and patented by IOC R&D Centre. Surya Nutan is a stationary, rechargeable and always kitchen connected indoor cooking solution capable of catering cooking needs of Indian households.

The product gets charged and discharged simultaneously while performing its function of indoor cooking. During use, the stored solar energy stored is recovered in a controlled manner for indoor cooking of a variety of Indian food items involving boiling, steaming, frying and “roti” making. The cooking system is suitable for family of 4 and can be modular in number and sizes as per requirement.
