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.
India is home to two major language families: Indo-Aryan (spoken by about 74% of the population) and Dravidian (spoken by 24% of the population). Other languages spoken in India come from the Austroasiatic and Sino-Tibetan language families. India has no national language. Hindi, with the largest number of speakers, is the official language of the government. English is used extensively in business and administration and has the status of a "subsidiary official language"; it is important in education, especially as a medium of higher education. Each state and union territory has one or more official languages, and the constitution recognises in particular 22 "scheduled languages".More Info
Despite economic growth during recent decades, India continues to face socio-economic challenges. In 2006, India contained the largest number of people living below the World Bank's international poverty line of US$1.25 per day. The proportion decreased from 60% in 1981 to 42% in 2005. Under the World Bank's later revised poverty line, it was 21% in 2011. 30.7% of India's children under the age of five are underweight. According to a Food and Agriculture Organization report in 2015, 15% of the population is undernourished. The Mid-Day Meal Scheme attempts to lower these rates.More Info
According to a 2011 PricewaterhouseCoopers (PwC) report, India's GDP at purchasing power parity could overtake that of the United States by 2045. During the next four decades, Indian GDP is expected to grow at an annualised average of 8%, making it potentially the world's fastest-growing major economy until 2050. The report highlights key growth factors: a young and rapidly growing working-age population; growth in the manufacturing sector because of rising education and engineering skill levels; and sustained growth of the consumer market driven by a rapidly growing middle-class. The World Bank cautions that, for India to achieve its economic potential, it must continue to focus on public sector reform, transport infrastructure, agricultural and rural development, removal of labour regulations, education, energy security, and public health and nutrition.More Info
In 1881, Charles Fritts created the first commercial solar panel, which was reported by Fritts as "continuous, constant and of considerable force not only by exposure to sunlight but also to dim, diffused daylight." However, these solar panels were very inefficient, especially compared to coal-fired power plants. In 1939, Russell Ohl created the solar cell design that is used in many modern solar panels. He patented his design in 1941. In 1954, this design was first used by Bell Labs to create the first commercially viable silicon solar cell. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs. The surface passivation process has since been critical to solar cell efficiency.More Info
A kurta, which traces its roots to Central Asian nomadic tunics, has evolved stylistically in India as a garment for everyday wear as well as for formal occasions. It is traditionally made of cotton or silk; it is worn plain or with embroidered decoration, such as chikan; and it can be loose or tight in the torso, typically falling either just above or somewhere below the wearer's knees. The sleeves of a traditional kurta fall to the wrist without narrowing, the ends hemmed but not cuffed; the kurta can be worn by both men and women; it is traditionally collarless, though standing collars are increasingly popular; and it can be worn over ordinary pyjamas, loose shalwars, churidars, or less traditionally over jeans.More Info
