Islamic Republic of Iran for the fifth development plan of 5000 MW of renewable energy Has planned. So far, only about 100 megawatts of renewable power plants, both wind and solar, have been installed in the country. Interestingly, the Fourth Development Plan also envisaged 2,000 megawatts of renewable electricity, which for some reason did not materialize. In this regard, we decided to develop a comprehensive plan for the construction of a solar power plant with extensive studies and review of the executive aspects of the work, which is provided at your service. Solar energy is one of the sources of renewable energy and one of the most important. The amount of solar energy varies in different parts of the world and has the highest amount in the Earth's solar belt. Iran is also located in the launch zones and studies show that the use of solar equipment in Iran is appropriate and can provide part of the energy needed by the country.

Iran is a country that according to experts in this field Despite 300 sunny days in more than two thirds of it and an average radiation of 5.5-4.5 kWh per square meter per day, one of the countries with high potential in the field of solar energy has been introduced. Some solar energy experts have gone a step further and claim that Iran, if it equips its desert area with radiation receiving systems, can also supply the energy needed by large parts of the region and be active in exporting electricity. Studies conducted by the German DLR, in an area of ​​more than 2000 square kilometers, it is possible to install more than 60,000 MW of solar thermal power plants. If we allocate an area equivalent to 100 × 100 square kilometers of land to build a photovoltaic solar power plant, its electricity production will be equal to the total electricity production of the country in 1389.

Photovoltaic cell converts sunlight directly into electrical energy . About 30 gigawatts of new photovoltaic capacity was put into operation worldwide in 2011 and increased by 70% to 70 gigawatts worldwide. The actual installation during 2011 was close to 25 GW, as some of the grid-connected capacities were installed in 2010. The operating capacity of photovoltaic systems at the end of 2011 was about 10 times the total installation Has been global for the past 5 years, bringing the average annual growth rate of 58% between 2006 and 2011. The film market share has fallen from 16% in 2010 to 15% in 2011. The leading countries with the most installed capacity by the end of 2011 were Germany, Italy, Japan, Spain and the United States. The other EU took over the market for photovoltaic systems due to the presence of Germany and Italy. Together, the two countries accounted for 57% of the new operational capacity in 2011. The European Union has about 17 gigawatts of installed capacity and has connected about 22 gigawatts of capacity to the grid. The total installed capacity of photovoltaic systems in the European Union by the end of 2011 was 51 gigawatts, which is about three-quarters of the total installed capacity worldwide. This will meet the electricity demand of more than 15 million European households. In Germany, the total installed capacity has reached 24.8 GW, which is 3.1% of the electricity generated in Germany (in 2010). This rate was 1.9%). Italy has set a new record, 9.3 GW of photovoltaic system entered the network, which reached 12.8 GW by the end of the year. Nearly 1 gigawatt), the United Kingdom (0.9 gigawatts), Greece (more than 0.4 gigawatts), Spain (nearly 0.4 gigawatts, which dropped from second to fourth in the world), Slovakia (0.3 gigawatts).

-3- Types of arrangements available for solar cells: Different types of inverters available in the market to connect to a three-phase network and consist of three single-phase converters, each connected to a load terminal. Inverters are divided into four categories depending on the arrangement of the solar cell: • Central inverters • String inverters • Multi-strand inverters • Alternating module inverters

The common method of transmitting electricity to consumers in recent decades is mainly power generation in large power plants, increasing the voltage to the desired level by transformers to reduce transmission losses, transmitting electricity through long lines to the consumer And finally one or more steps of voltage reduction for power supply to consumers. With increasing demand for electricity, restructuring in the electricity industry, and increasing the efficiency of small generation units, power companies are more inclined to shift subscribers to local electricity generation and supply.

Privatization of electricity industry and development of renewable energy are the most important factors in the development of this type of electricity production, the use of this type of power plants has a significant impact on the technical and economic components of commercial customers. Some of the advantages of using distributed generation power plants are:

1- Increasing reliability

2- Production on site, reducing network losses and freeing up the capacity of power transmission lines

3- Improving the mains voltage profile

4- Peaking

5- Using renewable energy technology and reducing environmental pollution

6- Possibility of simultaneous production of electricity, heating and cooling

7- Passive defense

8- Delaying network development costs

to invest in local production Various technologies are used in the world, one of which is the use of solar panels. Solar energy, the most unique source of energy ...
