The cost of constructing solar power plant is a MW

A common method of transferring electrical energy to the consumer in recent decades, mainly power generating in power stations; increasing the voltage to the extent desirable by Transformers to reduce transmission losses, transmission of electrical energy through lines elongated up near the consumer, and finally one or several stages, reducing the voltage to feed the consumer can be. With the increasing amount of demand for energy, electric restructuring in the electricity industry and also increase the efficiency of small manufacturing units, etc. power companies tend more to propel the subscribers to the local production of electricity and supply purposes of their own . خصوصی storage electricity industry and the development of renewable energy from the most important factors in the spread of this type of electricity production is the use of this type thermal power station has a significant influence on the components of technical and economic subscribers commercial can affect . Some of the advantages of power plants, distributed generation include: 1 - increase reliability 2 - production in location of consumption, reducing network losses, and the free storage capacity of the transmission lines, Energy 3 - improved profiles, the network voltage 4 - Courier سائی 5 - the use of technology of renewable energy and reduce the pollution of the environment 6 - the possibility of producing simultaneously electricity, heating and cooling 7 - passive defense 8 - deferral of development costs, networking, جهت investment in the local production of different technologies in the world use to be that one of them is the use of solar panels can be . Solar energy منحصربهفردترین source of renewable energy in the world and is the main source of all energies existing in the land. Solar energy for direct and indirect can be used to other forms of energy become crafted. Iran, having about 300 days of sunshine a year, among the best countries in the world in the field of the potential of solar energy in the world. Due to the geographical position of Iran and the dispersion of Rural in the country, the use of solar energy is one of the most important factors that should be considered. The use of solar energy is one of the best ways of electricity and the production of energy in comparison with other models the transfer of energy to the villages and remote places, in the country in terms of cost, حملنقل, maintain and factors the same. با according to international standards if the average radiant energy of the sun in the day, the higher of 3٫5 kilowatt-hours per sq. m. (3500 watt hours) is the use of solar energy, such as کلکتورهای solar or systems, photovoltaic, very economic and affordable. ICON in many parts of Iran radiant energy of the sun is much higher than the average of the international industry and in some parts even higher than 7, up to 8 KW hours on the meters measured, but the average radiant energy of the sun on the surface of the land of Iran, approximately 4٫5 KW hours on sq. m. is. 1-2-systems, photovoltaic با attention to the growing demand of the consumers in the country and increase in the cost of natural gas, and enforcing regulations on limiting emissions of greenhouse, the cost of production of electricity with the use of سوخ sadly, fossil has increased. For this reason, the approach to electricity using solar systems, photovoltaic, etc. increased. Of photovoltaic system due to the many benefits they are abundant application have. The first type them in the satellites of the synthetic tests and your performance to be efficiently carried out. Long lifespan(about 20 years), the ability to install and set up on the geographic conditions, especially like areas of the impassable and mountainous terrain, etc., usability in the systems, movable, easy maintenance, etc. the lack of dependence on the network in distant places and the ability to use to connect to the network all the benefits that are coming in the Vancouver area for the use of the photovoltaic outlining them. The amount of production of electricity through systems photovoltaic in the world every five years, doubled. Advances in industrial and the evolution of the technologies used in the production of cells, photovoltaic, etc., the productivity, the higher the and use than the systems in the. Thus, during the past two decades, the cost of the construction and installation of a photovoltaic system by about 20 percent, and be manufactured per unit installed is doubled. Generally, the system of photovoltaic suit their purpose into two groups of categories are: واحدهای photovoltaic connected to the grid. واحدهای photovoltaic is distinct from the network. سیستم of photovoltaic connected to the grid simultaneously and in parallel with grid power global be produced. Today, the system of photovoltaic grid-connected in many countries of the world in small units of 1کیلووات to 5 kW on the roofs of residential houses and units, more for power plants photovoltaic installation has been. Investors in this field in exchange for connecting solar power plant to the national network, electricity productive with your precious, suitable and advantageous to the Electricity Distribution Company to sell worldwide. همان in Table 1 are observed, investors can Solar Power produce their power lower than 10 MW to the price of the kilowatt-hour 637 USD to a network sell.

سیستم of photovoltaic grid power plant independent of the grid power national act and the ability to feed بارهایDC and alternate are capable of. These units directly to the load connected and all the times can supply them. So for the design of such units, must Model time and the whole of the be required times in a period of boarding will be calculated and the capacity of the unit and the number of array photovoltaic based on this calculated. Also, because of the lack of network, electricity, global, all be can be via the photovoltaic system supplier. از, since the photovoltaic system ability to generate continuous power, not (nightfall) and the amount of production, it can be quite to atmospheric conditions, affiliate is(reduced production on cloudy days, and rainy), etc. for proper nutrition, and make sure the load in a state detached from the sh ...
