Utility-scale on-grid solar power plants

Solar PV Station (PV farm or PV power plant) – a type of power generating facilities, using direct conversion of solar energy into electricity. Actually it is on-grid PV systems that generate electricity for transmission over the “green” tariff (Feed-in tariff) to a grid. Production of electricity from solar power has big opportunity for distributed generation.

The main advantages of network solar power plants are:

  • The use of free, renewable energy, practically available in unlimited amounts, – solar radiation, which, among other things, has no need to deliver to the place of electricity generation.
  • High reliability – Modern solar panels can be efficiently operated for 25 years. In addition, the station does not have moving / rotating parts, which are particularly not wear-resistant and require replacement.
  • Low operating costs – a modern solar power plant is characterized by a high degree of automation of all processes, and therefore requires a minimum number of service staff.
  • Maintenance of the solar stations for the plant’s efficiency support is very low-cost and does not require the carrying out of labor-intensive expensive operations.
  • The possibility of using not only free space for the construction of a solar power plant but also one that is used inefficiently or not at all, such as the facades and roofs of buildings that allows not only saving the territory, but also significantly reduces investment in the construction of the solar power plant.
  • The amounts of generation of electricity several times exceed those that were spent on its production.
  • The high speed of return on investment – investments in solar power pay off faster today, than in the oil and gas industry.

On-grid solar PV power plants

Solar PV station (solar farm, PV farm, solar plant, solar power plant or PV power plant) — a type of power generating facilities, using direct conversion of solar energy into electricity. Actually it is on-grid PV systems that generate electricity for transmission over the «green» tariff (Feed-in tariff) to a grid. Production of electricity from solar power has big opportunity for distributed generation.

Ways of solar radiation conversion are vary depending on the PV power plant design. Avenston engaged in engineering and construction of solar power plants using the photoelectric (photovoltaic) effect and are based on terrestrial silicon photovoltaic modules. Currently, this technology is dominant and is projected to remain the major within the next 15-20 years. Ways of solar radiation conversion are vary depending on the PV power plant design.

On-grid photovoltaic power system consists of the following components:

  • Solar modules.
  • Power inverters that convert the direct current (DC), generated by the solar panels into alternating current (AC).
  • A monitoring system to control the parameters of the solar power plant.
  • Measurement units to monitor the performance of the system and control the amount of electricity to sell it using the “green” tariff.
  • The supporting steel structures for placing solar panels on the ground, roof, etc.
  • Centralized grid and transmission line, which is connected to a power station.
  • Own electricity consumers (industrial or household appliances) as option.
