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.
Indian music ranges over various traditions and regional styles. Classical music encompasses two genres and their various folk offshoots: the northern Hindustani and southern Carnatic schools. Regionalised popular forms include filmi and folk music; the syncretic tradition of the bauls is a well-known form of the latter. Indian dance also features diverse folk and classical forms. Among the better-known folk dances are: the bhangra of Punjab, the bihu of Assam, the Jhumair and chhau of Jharkhand, Odisha and West Bengal, garba and dandiya of Gujarat, ghoomar of Rajasthan, and the lavani of Maharashtra. Eight dance forms, many with narrative forms and mythological elements, have been accorded classical dance status by India's National Academy of Music, Dance, and Drama. These are: bharatanatyam of the state of Tamil Nadu, kathak of Uttar Pradesh, kathakali and mohiniyattam of Kerala, kuchipudi of Andhra Pradesh, manipuri of Manipur, odissi of Odisha, and the sattriya of Assam. Theatre in India melds music, dance, and improvised or written dialogue. Often based on Hindu mythology, but also borrowing from medieval romances or social and political events, Indian theatre includes: the bhavai of Gujarat, the jatra of West Bengal, the nautanki and ramlila of North India, tamasha of Maharashtra, burrakatha of Andhra Pradesh, terukkuttu of Tamil Nadu, and the yakshagana of Karnataka. India has a theatre training institute the National School of Drama (NSD) that is situated at New Delhi It is an autonomous organisation under the Ministry of Culture, Government of India.The Indian film industry produces the world's most-watched cinema. Established regional cinematic traditions exist in the Assamese, Bengali, Bhojpuri, Hindi, Kannada, Malayalam, Punjabi, Gujarati, Marathi, Odia, Tamil, and Telugu languages. The Hindi language film industry (Bollywood) is the largest sector representing 43% of box office revenue, followed by the South Indian Telugu and Tamil film industries which represent 36% combined.
More InfoUntil the beginning of the first millennium CE, the ordinary dress of people in India was entirely unstitched. The arrival of the Kushans from Central Asia, circa 48 CE, popularised cut and sewn garments in the style of Central Asian favoured by the elite in northern India. However, it was not until Muslim rule was established, first with the Delhi sultanate and then the Mughal Empire, that the range of stitched clothes in India grew and their use became significantly more widespread. Among the various garments gradually establishing themselves in northern India during medieval and early-modern times and now commonly worn are: the shalwars and pyjamas both forms of trousers, as well as the tunics kurta and kameez. In southern India, however, the traditional draped garments were to see much longer continuous use.
More InfoIn the last 50 years, fashions have changed a great deal in India. Increasingly, in urban settings in northern India, the sari is no longer the apparel of everyday wear, transformed instead into one for formal occasions. The traditional shalwar kameez is rarely worn by younger women, who favour churidars or jeans. The kurtas worn by young men usually fall to the shins and are seldom plain. In white-collar office settings, ubiquitous air conditioning allows men to wear sports jackets year-round. For weddings and formal occasions, men in the middle- and upper classes often wear bandgala, or short Nehru jackets, with pants, with the groom and his groomsmen sporting sherwanis and churidars. The dhoti, the once universal garment of Hindu India, the wearing of which in the homespun and handwoven form of khadi allowed Gandhi to bring Indian nationalism to the millions,is seldom seen in the cities, reduced now, with brocaded border, to the liturgical vestments of Hindu priests.
More InfoWith 1,210,193,422 residents reported in the 2011 provisional census report, India is the world's second-most populous country. Its population grew by 17.64% from 2001 to 2011, compared to 21.54% growth in the previous decade (1991–2001). The human sex ratio, according to the 2011 census, is 940 females per 1,000 males. The median age was 27.6 as of 2016. The first post-colonial census, conducted in 1951, counted 361 million people. Medical advances made in the last 50 years as well as increased agricultural productivity brought about by the "Green Revolution" have caused India's population to grow rapidly.
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.
