The cells are made of two chips of silicon crystals with junctions between them. This building can get as hot as 5,790. Though in the future many more homes will be solar heated. Sun) is safe, free and environmental friendly.
Though these windmills were used to pump water or to grind grain. In a passive solar home there is no machinery, but there are windows and the floors and windows are made of materials that absorbs heat, like adobe. The sunrays heat the water-filled copper tubes. They consist of a mirror or mirrors which are focused in one spot. On the last day in the morning there was no change from the night before. Although the initial cost of solar water heaters is higher than that of conventional water heaters. When the oil is heated it is piped to a power plant where it is used to produce steam that turns a turbine. Also ground solar power plants are predicted to be used more frequently. In building the use of renewable energy technologies are being widely studied and applied them.
The first kind is a flat plate collector. This would allow the solar cells not to be obstructed by clouds or buildings. The solar energy received by the total land of India is about 19 trillion kwh per day, which is about.2 million tonnes of oil equivalent. With the help of solar energy this can change and is already changing.
