Services
Providing consulting engineering services (study, design and supervision) in the specialty of production, transmission and distribution of electricity through solar power plants
o On-Grid Power plants
Considering that in line with the implementation of Article 44 of the Constitution regarding the development of the participation of the non-governmental sector in the country's economic activities and to protect fossil energy sources, protect the environment, and diversify energy sources, the Organization of Renewable Energy and Energy Efficiency ( Satba) has put the guaranteed purchase of non-governmental renewable and clean power plants at the top of its plans, this company can design On-grid photovoltaic systems by relying on its experience. It should be mentioned that the difference between this type of power plant with Off-Grid power plants is that they produce power simultaneously and parallel to the entire power grid. At night, when solar energy is not available, electricity is purchased from the national grid and used to supply the system load. In this method, in addition to providing part of the electrical energy needed by the consumer, excess energy is injected into the national electricity grid.
o Off-grid Power plants
The design of this type of solar system is for providing electricity in situations where it is mainly for supplying electricity to residential buildings, villas, administrative and commercial centers on the highway, etc., which are far from the electricity grid or to obtain electricity branching. It is not possible due to restrictions. The equipment used in these systems includes solar panels to receive solar energy, charge controllers to control and charge the system batteries, inverters to produce AC electricity, and batteries to store the produced energy.
- Monitoring system
Considering that during the operation of solar power plants, its performance is affected by various factors such as adverse environmental conditions, mechanical defects and electrical circuits, it can lead to loss of power and income. Therefore, it is necessary to have a 24-hour monitoring syst
em. Among the advantages of using the system provided by Arman Sharif Energy Development Company, the following can be mentioned:
- 1- Provision of a local server that determines the necessary data by providing all the required infrastructure and stores it in a data center. Saves without the need for the Internet.
- 2- Domestic/international access, Internet and intranet: this system can be provided with access to the Internet in such a way that the access method and conditions can be designed according to the customer's policies.
- 3- Hardware flexibility: this system can be engineered and implemented for various types of power plant components with protocols such as Ethernet, WLAN, Modbus TCP, Modbus RTU, CAN, RS485, and RS233.
- 4- Taylor-style local data monitoring platform: after forming a local data center, an execution platform will be developed according to the design of the power plant and customer requirements;
By using it, the operator can have access to all the data of the power plant, which contains the details of the production information, either in the form of post or sub-network of the post.
- 5- Web monitoring system: This system is provided through online monitoring in Taylor mode, which can access the system through the Internet or intranet. Therefore, all the capacities of the local network can be reached through the Internet.
- 6- Possibility of automatic reporting: this system can send automatic reports in the form of email and save a copy of it in PDF format on the local server. The layout, contents and format of the report are prepared and sent according to each customer's request.

According to the executive records and a wide range of internal and external communications that the parent company has acquired over the years and by the experienced people of its team in similar projects, Arman Sharif Energy Development Company can introduce The top suppliers to provide the necessary support and also manage the negotiations with the suppliers from the initial to the final stages of concluding the contract and purchase of equipment to provide the maximum resources of its customers.
- Installation, implementation and operation
Standard installation ensures correct operation and high efficiency of power plants during operation. Therefore, the commitment to complying with the power quality standards set for different levels of the network becomes doubly necessary. All the implementation methods of this company are by the latest international and domestic standards and requirements, and the correct and high-quality implementation of the project using the best quality equipment and complying with all technical, protection and operational requirements, regardless of the reduction of implementation costs, is guaranteed. He will be responsible for implemented projects.
- Inspection and troubleshooting, repairs and maintenance of solar power plants
- Aerial thermography of solar power plants
Considering that conducting thermography tests in large-scale solar power plants on the ground requires time and high cost, this company was able to perform this test by the necessary standards and with the help of the necessary aerial equipment, and the report presents defects such as hot spots, string interruptions, diode performance, etc.
With the help of the equipment related to this test, by applying current and voltage to each module or string, a voltage-current curve is obtained as an output, by comparing this diagram and the diagram in the data provided by the manufacturer, several Defects can be identified.
- EL or electroluminescence test
One of the most important methods for diagnosing PID defects in solar modules is using the electroluminescence test. The performance mechanism of this test is based on the injection of electric current into the module and the emission of infrared rays and detection by cameras dedicated to this work. This phenomenon, which is called "electroluminescence", will cause the damaged parts to generate radiation with a lower or greater intensity than the healthy parts of the module. Arman Sharif Energy Development Company provides relevant services by using advanced and up-to-date equipment.
o Panel washing
Dust and bird droppings are among the most common pollutants in solar panels. These pollutions are an obstacle for direct sunlight to the panels and affect the performance of the panel. Dirty panels produce less energy than clean panels. Rain can sometimes clean the solar panels, but this is not always possible because many solar power plants are installed in dry and desert areas and the rain is not enough to clean the systems. Also, the rain is not enough to remove bird droppings and more force is needed to remove them. In addition, in many power plants, to use the space optimally, solar panels are placed with brackets at a high height, which are much harder to clean. Therefore, specialized equipment should be used to wash the panels, which will not harm them at the same time as removing the pollution of the panels. This service can be implemented using manual and mechanized washing systems by Arman Sharif Energy Development Company.
