Product Description

The Solar PV Cook-stove is designed to use sunlight to cook all types of food typically eaten in India, at any time of day or night. It uses induction rings to heat the pan/pot meaning it can be used to cook indoors and can achieve temperatures over 160°C making it capable of being used for cooking all types of typical Indian cuisine.

The system is capable of supplying 3 kWh of energy sufficient to cook 3 meals per day for a 5 person family. It is powered by 4 solar PV panels providing 1 kW of power, with 4 Lead Acid batteries (total storage 7 kWh) to enable cooking at night and provide a day of back up for rainy or overcast conditions.

The Solar PV Cook-stove was designed and developed by Solar Urja through Localization for Sustainability (SoULS) initiative of the Indian Institute of Technology (IIT) Bombay. It is currently being piloted in Bancha village of Betul district, Madhya Pradesh, India.

Design Specifications

The Solar PV Cook-stove is designed to use sunlight to cook all types of food typically eaten in India, at any time of day or night. The design includes one or two 1 kW induction rings depending on the model and an optional 500 W resistive cooker to heat the pots and pans. The induction rings are capable of producing cooking temperatures over 160 °C making it capable of being used for cooking all types of typical Indian cuisine. The developers specify that "It can be used for all cooking processes like boiling, steaming, frying, griddling, etc." The largest version of the system is capable of supplying 3 kWh of energy sufficient to cook 3 meals per day for a 5 person family. It operates on 48 V DC electricity produced by 4 solar PV panels providing a total of 1 kW of power. 4 Lead Acid batteries (total storage 7 kWh) enable cooking at night and provide a day of back up for rainy or overcast conditions. The induction rings are housed in a plastic casing designed to increase durability and ease of use of the cookstove and safety for the user. The casing has a battery power meter to indicate it's state of charge and usage and ventilation gaps in the sides. For the larger model, the rings power levels are adjusted using rotatable knobs similar to those found on typical electric hobs for usability, while on the smaller model three switches control the degree of heat. The commercially available smaller model of the cookstove (single ring) weighs approximately 1 kg (excluding panels and batteries) and has the following specifications:

Component Specifications
Heating Coil 100% Pure Copper litz wire Coil
Maximum Power Output A-Grade High Strength German Crystal Top Plate
Top Plate Material 100% Pure Copper litz wire Coil
Input Voltage 40 V to 60 V DC
Battery level Display Yes (LED’s with )
Power Adjustments (W) 3 levels ( 700-1000 W)
Auto Pan detection, Switch off Yes, Automatically switch off when no pan on the induction cooker
Utensil to be Used Use Flat-Bottom Normal Stainless Steel Utensils only
Internal Cooling Fan Type DC Fan 18V
PCB Quality A-Grade Quality
Body Material ABS Mixed PP Plastic For High Strength
Warranty 1 Year Manufacturer Warranty
Compliance Compliance with ISO 9001-2008 Certified

Product Schematics

Technical Support

For those using the product in Bancha village under the pilot, two villagers have been trained to maintain the stoves, and IIT-Bombay are still monitoring the pilot so can provide additional technical support as needed.

Replacement Components

Replaceable components include the batteries and solar panels.


Dr. Solanki, a professor at IIT-Bombay who supervised the team that designed the Solar PV Cook-stove, estimates the lifetime for similar products at 20 years and 5 years for batteries. A 1 year manufacturer's warranty is provided with the cookstove.

Manufacturer Specified Performance Parameters

The product was designed to achieve a high score in all of the 5C's (Convenience, Control, Cost-effectiveness, clean and compactness) which are criteria for comparing modern cooking solutions. It was intended to not produce any air pollution to address the indoor air pollution problem with existing stoves that have caused negative health outcomes. It can fulfill the energy demand to cook 3 meals a day for a family of 5 people and can be operated at night in contrast to other solar cookstoves.

Vetted Performance Status

Testing performed by the manufacturer determined the cookstove offers 3-4 hour cooking time per day on a full charge and is both suitable for all types of domestic cooking processes and sufficient for a family of 5 members. Manufacturer testing results are in the below table. No third-party testing has been completed.Interview with representative in 2020  


The product uses a 48 V DC power supply from it's solar panels and batteries to improve electrical safety, however users should take appropriate precautions when using electrical devices and be cautious that the stove-top may remain hot for some time after cooking.

Complementary Technical Systems

Use of insulated vessels capable of induction cooking can reduce the energy requirement for the cookstove by 10%. It would be possible to power other electrical appliances using the electricity stored in the lead-acid batteries. IIT Bombay has also developed a solar PV rice cooker and a solar tea cart.

Other Information

In September 2018, a Know-how and licensing transfer event was held to share knowledge and licensing rights relating to the product with other parties. A video of Prof Solanki presenting his research on the Dawn of Solar PV Cooking (linked in academic research above) can be found here. Two videos demonstrating the Solar PV Cook-stove can be found here and here. The Solar PV Cook-stove is currently being piloted in 74 homes in Bancha village of Betul district, Madhya Pradesh, India. India Today produced a video showing the impact of the solar PV cook-stove on Bacha village in Betul district, Madhya Pradesh. There are plans to expand the pilot to a village in Hoshangabad district, Madhya Pradesh. This product won the Oil and Natural Gas Corporation's Solar Chulha Challenge which was intended to encourage development of an alternative to the biomass-fueled chulhas used by 700 million Indians.
