Solar power is the generation of electricity from sunlight. This can be direct as with photovoltaics (PV), or indirect as with concentrating solar power (CSP), where the sun's energy is focused to boil water which is then used to provide power. The solar power gained from photovoltaics can be used to eliminate the need for purchased electricity (usually electricity gained from burning fossil fuels) or, if energy gained from photovoltaics exceeds the home's requirements, the extra electricity can be sold back to the home's supplier of energy, typically for credit. The largest solar power plants, like the 354 MW SEGS, are concentrating solar thermal plants, but recently multi-megawatt photovoltaic plants have been built. Completed in 2008, the 46 MW Moura photovoltaic power station in Portugal and the 40 MW Waldpolenz Solar Park in Germany are characteristic of the trend toward larger photovoltaic power stations. Much larger ones are proposed, such as the 100 MW Fort Peck Solar Farm, the 550 MW Topaz Solar Farm, and the 600 MW Rancho Cielo Solar Farm. Solar power is a predictably intermittent energy source, meaning that whilst solar power is not available at all times, we can predict with a very good degree of accuracy when it will and will not be available. Some technologies, such as solar thermal concentrators have an element of thermal storage, such as molten salts. These store spare solar energy in the form of heat which is made available overnight or during periods that solar power is not available to produce electricity.

It seemed like it would only be a matter of time beforeToyota would jump into the market of using renewable energy to charge a car and they have done so in a big way. The solar charging station by Toyota will be put on display at the Tokyo Motor Show 2009. While there are other charging stations on the market for electric cars, the fact that this one is solar powered has the industry abuzz in anticipation. The solar charging station by Toyota almost looks like something that you would have seen in one of the old sci-fi movies, but this is the real deal. It works by collecting the suns energy through solar panels and then stores the energy in a battery that is later used to charge and power the vehicle. This is just another great innovation that is pushing our world to a 'greener' lifestyle and will use renewable energy in yet another every day application.
When we think about going solar we make a mental picture of large heavy panels adorning one’s rooftop. But researchers are trying to get rid of bulky solar panels. They are aiming to achieve this feat with the help of zinc oxide nanostructures grown on optical fibers and coated with dye-sensitized solar cell materials. Researchers at the Georgia Institute of Technology have built up a new kind of three-dimensional photovoltaic system. This three-dimensional photovoltaic system will not be heavy and it will not occupy a place of prominence on rooftops; it can be hidden from the view. No Comments
Solar power is produced by collecting sunlight and converting it into electricity. This is done by using solar panels, which are large flat panels made up of many individual solar cells. It is most often used in remote locations, although it is becoming more popular in urban areas as well. This page contains articles that explore advances in solar energy technology.
Solar refrigeration units can be provided to each village dispensary where various medicines including the anti venom injections are provided. Water purification plants and Water Desalination units provide supply of clean portable drinking water to the users.
Solar energy is a potentially available renewable energy source in this region. This source can be utilized as an excellent alternative to fossil fuels for these areas. Solar energy resource is planned to successfully utilize for household applications and electrification of remotest villages of these areas. The outcomes of this program are social uplift, betterment and provision of basic amenities of life.
