Our visit to Tata BP Solar today consisted of a tour through the manufacture line and a discussion about the company. Approximately 200 people are employed at Tata for the assembly line alone. It was interesting to watch as the solar cells (which begin as gray squares which are about 6 x 6″) were placed on conveyor belts glazed with chemicals, and flashed with lights. The assembly lines perfect one side of the cell at a time, and then the cells are sent through more machines to complete the process on the other side. During the last stages of the assembly lines, the cell is tested with a light that resembles sunlight to test how much energy the cell produces. On average, most cells here produce about 3.6 watts. Most cells are sold locally and homes in India which use the cells most commonly use them to heat their water or for lighting. This plant is operated 24 hours a day and produces about 24,000 cells per day. The cells are said to last about 25 years before they need repairs or replaced. The smallest finished panel is made of 4 cells, and the largest can be as large as you have room for. The size is mostly determined by energy needs, money, and space.
