Most significant solar cooking projects
- January 2013: World's largest solar cooking class takes place in India - On January 19, 2013, middle school students gathered on the grounds of JES College in Jalna, India to be trained in the use of a simple solar panel cooker. After a quick breakfast, and guidance from 205 trainers, a record-breaking 2,044 students assembled their own solar cooker and placed prepared ingredients inside to cook. After speaker presentations, they were able to enjoy the lunch they had cooked themselves. This event, sponsored by Simplified Technology for Life, demonstrates that India is quite serious about introducing solar cooking to young students. Ajay Chandak reports that included in the Indian government's five-year plan for 2012 through 2016, 30,000 million INR (approx. $600,000,000USD) is budgeted for solar cooking instruction in 500,000 schools.
- April 2010: Gadhia Solar Energy Systems Pvt. Ltd. recently completed installation of an enormous solar steam cooking system, capable of cooking 40,000-50,000 meals per day. It is located at Shirdi Saibaba temple in Shirdi, Maharashtra, India. With nearly 30,000 visitors each day, the temple’s dining halls are some of the largest in India. The solar steam cooking system is comprised of seventy-three rooftop-mounted Scheffler reflectors of sixteen square meters each. The dishes concentrate sunlight on receivers that contain water, generating steam that is piped down to the kitchen for cooking purposes. To maintain constant focus with the sun, the dishes automatically rotate throughout the day after being manually aligned once each morning. The solar steam cooking system is retrofitted to existing liquid petroleum gas-powered steam boilers that are still used in the evening and during prolonged periods of inclement weather. Though the solar steam cooking system cost nearly $300,000, government subsidies reduced the temple’s portion to about $170,000. Liquid petroleum gas use has been cut by roughly 100,000 kilograms each year, for an annual savings of approximately $45,000. The temple should recoup its investment in three to four years. According to company founder Deepak Gadhia, the solar steam cooking technology was originally developed in Germany. However, the equipment does not contain imported components and is manufactured with local machinery and labor, creating much-needed jobs. Gadhia has adapted the system for use in India, and has installed 50 such systems of varying sizes over the past two decades. The March edition of CNN’s Eco Solutions program highlights the Shirdi Saibaba temple solar steam cooking system.

Gadhia has adapted the system for use in India, and has installed 50 such systems of varying sizes over the past two decades. The March edition of CNN’s Eco Solutions program highlights the Shirdi Saibaba temple solar steam cooking system.
The History of Solar Cooking in India
India, Asia's second largest country, next to China, has also the second largest number of solar cookers. The situation in India is more complex than that of China. More is also known about Indian programs. The Third World Conference on Solar Cooking was held in India, permitting the history and progress of solar the technology's uses to become better known around the world.
An official government report informs the reader that the Ministry of Non-Conventional Energy Sources (MNES), Government of India, was established in 1982, first as a Department and later as a Ministry. The Ministry's mandate extends well beyond solar cooking, including fuel efficient wood and charcoal stoves, power from other renewable sources, energy from industrial wastes, research and development in a number of related fields (photovoltaics, biogas, and pollution prevention, for example). MNES began seriously to promote solar cooking in the early 80s, with an initial focus almost entirely on the box cooker.
The population of India is roughly 70% rural. MNES states that "cooking accounts for a major share of the total energy consumption in rural homes (Singhal, correspondence, 2003, p. 1). Sources of that energy are largely fuelwood, animal dung, or crop residues, all of which emit smoke, pollute the atmosphere, and are deterimental to health and safety of family members, particularly women. Fuelwood is become scarcer each year. FAO data show that 21.6% of the Indian land mass is forested, and conservation efforts are in place to reverse previous loss. The effort is affected by the large and dense population and a slowing but still substantial birth rate (continuing to increase at 1.7% per annum, or 17% in a decade). Solar cooking has been viewed as one way to alleviate a number of India's problems and as such was supported by government efforts.
The Press Bureau of the Government of India reported in 2007 that there are 525,000 solar cookers installed in India. The Press Bureau also reported in 2003 that, "The solar cooker programme has been expanded by introducing new designs for community use. Three solar steam cooking systems based on automatic tracking concentrating collective technology for cooking food for 600-3,000 people per day, and one system based on ‘Solar Bowl’ technology, have been installed. World's largest solar steam cooking system has been installed at Tirumala Tirupati. The system is designed to cook two meals for 15,000 persons in one day. Another system for 2,000 people was erected at Brahmakumaris Ashram in Gurgaon in July, 2002. Three community cookers for indoor cooking have been installed at a training hostel and an NGO’s establishment in Leh. In all, six such systems have been installed under the MNES demonstration scheme. A total of 500 dish solar cookers and 60 community solar cookers have been installed so far."
Culture and Economics
Solar Cookers International has rated India as the #1 country worldwide for solar cooking potential. In the year 2020, the estimated number of people in India who will suffer from fuel scarcity is 157,400,000, but these people will continue to have ample access to the sun. In December 2007, the Indian Government instituted a program of rebates on various renewable energy devices including solar cookers. Solar cooking has even been recommended in the Rig Veda, a sacred Hindu text, stating: "All edibles ripened or cooked in the sun’s rays change into super medicine, the amrita."
Fuels used for cooking
- LPG (47.96%)
- Firewood (22.74%)
- Kerosene (19.16%) and
- Other fuels(10.14)
- Firewood (64.10%)
- Other sources of biomass – crop residue (13.10%)
- Cow‐dung (12.80%), and
- LPG (5.67%) is now increasing in importance. 
The Economic Times of India reports:
- While 300 million people live below poverty line, making do with energy inefficient dung cakes, twigs and branches, and occasional bits of coal, the urban middle class and the rural rich are splurging on cheap petrol and diesel and even cheaper kerosene and liquified petroleum gas.
- The subsidy is massive - hidden by a disingenuous device called oil bonds. Here are some rock solid facts. IOC, HPCL and BPCL are currently losing $137 million a day (i.e., Rs 582 crore per day at Rs 42.50 = $1). They lose Rs 16.34 for each litre of petrol, and Rs 23.49 for each litre of diesel sold in Delhi.
- The subsidy on kerosene at Rs 28.72 per litre is over three times the current retail price; and the subsidy on a cylinder of cooking gas at Rs 306 per cylinder exceeds the retail price. The total under-recovery for the oil marketing companies for 2006-07 was over $19 billion. With oil prices touching $135, under-recoveries can be $50 billion this year, unless retail prices are substantially increased.
The Telegraph (UK) reported in September 2013 that, "Food and fuel subsidies are gobbling up much of the budget, while investment atrophies."
Solar cooking already has a significant presense in India, especially with large scale projects, but the potential remains for its use to still significantly replace the use of conventioal fuels.
In a report presented during the Asian Clean Energy Forum in June 2008, Soma Dutta, Asia Regional Network Coordinator for the Amsterdam-based ENERGIA International Network on Gender and Sustainable Energy, states that only 45% of India’s 70% rural population have access to electricity, and over 80 percent still rely on firewood as their primary cooking fuel, the gathering of which is a responsibility that almost always falls to the women and girls in a society. The long hours and significant effort spent simply gathering firewood leaves them little time for education or employment. 
Introductions of new technologies fail in villages for many reasons, but most commonly due to a lack of knowledge and understanding of local cultural customs. Solar cooking has often suffered this fate despite the purported cost savings because it is not introduced in a way that suited the lifestyles of the individuals using it.
A solar stove is most powerful at the times of the strongest sunlight, which is mid-day and early afternoon. As in many agricultural populations, village farmers in India consume their biggest meals by early to mid-morning and then again late at night, after the sun has set. In addition, certain solar stoves are not conducive to Indian-style cooking which is done mostly with oil (with the exception of rice) and requires frequent temperature manipulation as well as stirring and flipping which was is difficult with many solar cookers.
While technical constraints limit the types of solar cookers likely to be widely adopted in India, there is historic precedent for solar cooking in Indian culture. A passage in ancient Vedic texts state, " Sun cooked food improves cellular health and longevity of life. It strengthens health and mind removes three major physical disorders to do with digestion, blood and respiratory system, balances inner body temperatures, life, glows aura and keeps various obstacles away. Sun cooked food has great medicinal value. It enhances intellect, genius." ' Rig Veda'. - Reference from the princeindia.org website. See: PRINCE
