Average pricing information divides in three pricing categories: those buying small quantities (modules of all sizes in the kilowatt range annually), mid-range buyers (typically up to 10 MWp annually), and large quantity buyers (self-explanatory—and with access to the lowest prices). Over the long term there is clearly a systematic reduction in the price of cells and modules. For example, in 2012 it was estimated that the quantity cost per watt was about US$0.60, which was 250 times lower than the cost in 1970 of US$150. A 2015 study shows price/kWh dropping by 10% per year since 1980, and predicts that solar could contribute 20% of total electricity consumption by 2030, whereas the International Energy Agency predicts 16% by 2050.
Family values are important in the Indian tradition, and multi-generational patriarchal joint families have been the norm in India, though nuclear families are becoming common in urban areas. An overwhelming majority of Indians, with their consent, have their marriages arranged by their parents or other family elders. Marriage is thought to be for life, and the divorce rate is extremely low, with less than one in a thousand marriages ending in divorce. Child marriages are common, especially in rural areas; many women wed before reaching 18, which is their legal marriageable age. Female infanticide in India, and lately female foeticide, have created skewed gender ratios; the number of missing women in the country quadrupled from 15 million to 63 million in the 50-year period ending in 2014, faster than the population growth during the same period, and constituting 20 percent of India's female electorate. Accord to an Indian government study, an additional 21 million girls are unwanted and do not receive adequate care. Despite a government ban on sex-selective foeticide, the practice remains commonplace in India, the result of a preference for boys in a patriarchal society. The payment of dowry, although illegal, remains widespread across class lines. Deaths resulting from dowry, mostly from bride burning, are on the rise, despite stringent anti-dowry laws.

More InfoIn the last millennium, the most significant import of cooking techniques into India occurred during the Mughal Empire. The cultivation of rice had spread much earlier from India to Central and West Asia; however, it was during Mughal rule that dishes, such as the pilaf, developed in the interim during the Abbasid caliphate, and cooking techniques such as the marinating of meat in yogurt, spread into northern India from regions to its northwest. To the simple yogurt marinade of Persia, onions, garlic, almonds, and spices began to be added in India. Rice grown to the southwest of the Mughal capital, Agra, which had become famous in the Islamic world for its fine grain, was partially cooked and layered alternately with the sauteed meat, the pot sealed tightly, and slow cooked according to another Persian cooking technique, to produce what has today become the Indian biryani, a feature of festive dining in many parts of India.In food served in restaurants in urban north India, and internationally, the diversity of Indian food has been partially concealed by the dominance of Punjabi cuisine. This was caused in large part by an entrepreneurial response among people from the Punjab region who had been displaced by the 1947 partition of India, and had arrived in India as refugees. The identification of Indian cuisine with the tandoori chicken—cooked in the tandoor oven, which had traditionally been used for baking bread in the rural Punjab and the Delhi region, especially among Muslims, but which is originally from Central Asia—dates to this period.
More InfoModule performance is generally rated under standard test conditions (STC): irradiance of 1,000 W/m2, solar spectrum of AM 1.5 and module temperature at 25°C. The actual voltage and current output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage, current, or wattage at which the module operates. Performance varies depending on the time of day, amount of solar insolation, direction and tilt of modules, cloud cover, shading, state of charge, temperature, geographic location, and day of the year. The fluctuations in voltage and current can be logged with a multimeter or data logger.
More InfoThe average life expectancy in India is at 68 years—69.6 years for women, 67.3 years for men. There are around 50 physicians per 100,000 Indians. Migration from rural to urban areas has been an important dynamic in India's recent history. The number of people living in urban areas grew by 31.2% between 1991 and 2001. Yet, in 2001, over 70% still lived in rural areas. The level of urbanisation increased further from 27.81% in the 2001 Census to 31.16% in the 2011 Census. The slowing down of the overall population growth rate was due to the sharp decline in the growth rate in rural areas since 1991. According to the 2011 census, there are 53 million-plus urban agglomerations in India; among them Mumbai, Delhi, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad, in decreasing order by population. The literacy rate in 2011 was 74.04%: 65.46% among females and 82.14% among males. The rural-urban literacy gap, which was 21.2 percentage points in 2001, dropped to 16.1 percentage points in 2011. The improvement in the rural literacy rate is twice that of urban areas. Kerala is the most literate state with 93.91% literacy; while Bihar the least with 63.82%.
