They are 15-20% more efficient whereas the other two forms tend to be 13-16% efficient and if we talk about prices then mono-crystalline version is quite expensive. I created professional CVs, professional profiles, and professional cover letters which accompanied CVs to leading companies all over the world. Like the parabolic and linear systems, the dish-shaped, mirror clad, surface directs and concentrates sunlight onto a thermal receiver at the dish's focal point. Many industrialized nations have installed significant solar power capacity into their grids to supplement or provide an alternative to conventional energy sources while an increasing number of less developed nations have turned to solar to reduce dependence on expensive imported fuels (see solar power by country). The Direct current(DC) then needs to be converted to Alternating current(AC) using an inverter, before it can be used or fed into the electrical grid. I was forced to resign due to the overwhelming pain and severe memory and concentration problems in 2008 and have been doing freelance work ever since. I home schooled our three children from grade 0. These systems use Fresnel lens effect, which allows the use of large focusing mirror with short focal length and large aperture, and this type of setup allows to focus sunlight around 30 times more than the normal intensity. There are also other examples at the Bhuj in India and was completed in 1993. Photovoltaic power plants generate electricity and then that electricity is fed directly into the national grid. In the tower, the solar energy is used to heat the air at 700 degree Celsius. What better way to do that than going solar. Since the area-specific power density is limited, the irradiation is concentrated by an optical system onto an absorber to obtain elevated temperatures allowing an effective transformation of heat into mechanical work. Save my name, email, and website in this browser for the next time I comment. This was developed to lift water for irrigation purposes. Solar panels that convert solar power into electricity usually generate DC current with voltages up to 1500v. The two types are Photo-voltaic power plants and second one is solar thermal power plants. Solar power plants work on solar energy which is available in abundant on the earth surface at most of the places. Most solar energy plants use the thermal power of the sun to heat reservoirs of fluid and power turbines. Photovoltaic power plants are quite different from other solar power plants as they utilize the photoelectric effect directly without there being a need to use other devices or processes. This alignment allows the sun tracking mirrors to track the light throughout the day. They help in keeping the environment pollution free . This setup allows the banks of mirrors to track the sun from east to west throughout the day. These kinds of solar thermal power plant work by focussing sunlight from long parabolic mirrors onto receiver tubes that run the length of the mirror at their focal point. On average the high-salinity water can reach 90 degrees Celsius with low-salinity layers maintaining around 30 degrees Celsius. Because of their parabolic shape, these kinds of reflectors are able to focus between. Your email address will not be published. This technique acts as a thermal trap inside the lake which can either be utilized at that point of time or can be stored for later use. In this article we will elaborate more on the different types of solar power plants and also go through their working mechanism as to how they harness solar energy and produce electricity. If we talk about in terms of efficiency then mono-crystalline versions are more efficient than others are. Solar thermal power plants can be categorized or subdivided into three types, … In the following article, we'll take a quick look at the different types of solar power plants that harness the sun's life-giving sunlight to produce electricity. Hence, this shows the durability and the quality which in turns give great results in terms of producing or generating electricity. The thermal energy-storage capability allows the system to produce electricity during cloudy weather or at night. PV panels do not concentrate energy they simply convert photons into electricity that is then transmitted somewhere else. Salt concentrations levels increase with depth and, therefore, density also increases from the surface to bottom of the lake until the solution becomes uniform at a given depth. These semiconductors project a property where they absorb the photons and release electrons and this phenomenon is known as photoelectric effect. Solar power towers are an interesting method in which hundreds to thousands of flat sun-tracking mirrors (heliostats) reflect and concentrate solar energy onto a central tower. Easy DIY Power Plan is a new do-it-yourself program for those interested in becoming energy-independent by building their own miniature “home power plants. - Solar panels that convert sunlight into useful electricity. This is the principle photoelectric effect which we mentioned earlier as well. They tend to consist of three discrete types of system: Parabolic troughs use parabola-shaped reflectors that are able to focus between 30 and 100 times normal sunlight levels on to the collector. In spite of certain drawbacks, the solar power plants make the right use of the sun’s energy and have till date been successful in supplying electricity all over the world. Construction and working principle of Solar power plant Figure shows a solar power plant with a low temperature solar engine using heated water from flat plate solar collector and Butane as the working fluid. As compared to linear concentrating systems, the concentration ratio of solar dish systems is much higher. Then with the help of a turbine, this hot salty water can be used for the production of electricity or as a source of thermal energy. Solar thermal power plants can also be subdivided into a further three distinct types: -. This makes these towers really appealing and these are very well suited for operating in adverse weather conditions. A solar power plant is any type of facility that converts sunlight either directly, like Photovoltaics, or indirectly, like Solar Thermal plants, into electricity. Likewise, a few towers utilize water as the heat transfer fluid. Generated steam runs the turbine coupled to a generator which produces electrical energy in Thermal Power Plants. Long distance transmission allows remote renewable energy resources to displace fossil fuel consumption. These sorts of solar thermal power plants work by concentrating sunlight from huge parabolic mirrors onto recipient tubes that run the length of the mirror at their point of convergence. As a rule of thumb monocrystalline versions are more efficient (about 15-20%) but more expensive than their alternatives (tend to be 13-16% efficient) but advancements are closing the gap between them over time. PV panels are distinct from other solar power plants as they use the photo-effect directly without the need for other processes or devices. Power generating equipment can either be directly mounted at the dish's focal point (great for remote locations) or collected from an array of dishes and electrical generation occurring at a central point. Salt fixations levels increment with depth, and accordingly, density also increments from the surface to base of the lake until the arrangement winds up uniform at a given depth. In the solar photovoltaic system, solar energy is directly converted to electric power. solarpowernerd.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to. Solar energy is available at free of cost. This process focuses thermal energy and reduces the loss of heat from the water. - Thin-film solar panels - These types of panels consist of a series of films that absorb light in different parts of the EM spectrum. Solar pond power plants utilize a pool of saltwater that collects and stores solar thermal energy and it uses a technique known as salinity-gradient technology. This is an interesting method, which uses hundreds and thousands of flat sun-tracking mirrors called heliostats, which concentrate and reflect solar power onto a central tower. The last plant built, SEGS IX, with an electricity generation capacity of 92 megawatts (MW), began operation in 1990.
