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.

Construction of on-grid PV power plants

To date, several technologies have been developed and actively used to generate solar energy on an industrial scale. In the design and construction of solar power plants that use the photoelectric effect, our company uses silicon photovoltaic modules of ground application, which are characterized by optimal price / quality ratio. Currently, this technology of transforming solar energy into electric power is dominant and, according to experts, will remain for such, at least, the next 15-20 years. The design of the solar panels of the specified type allows to provide high efficiency, combined with high reliability and protection of solar stations. The advantage of photoelectric modules of this type is their very long lifespan – not less than 25-30 years. At the same time, the reduction in power caused by the natural aging of components, which include the photovoltaic module, is no more than 20% after 25 years of operation of the solar power plant.

We provide services for the implementation of projects for the construction of solar power stations throughout the territory of Ukraine. We are ready to offer the installation as a typical solar power plant project, as well as to develop an individual variant, which will take into account all the wishes of the customer and peculiarities of the place (object), where the installation will be carried out. Within the framework of cooperation Avenston offers:

  • Development of project effectiveness, which takes into account specific territorial factors that can influence the power generating facilities and develop methods for minimizing their impact.
  • Cost calculation for solar power plant (CAPEX).
  • Solar Power Payments Calculations (IRR).
  • System design and detailing of all units of the solar power plant and engineering.
  • Selection, procurement and delivery of all necessary equipment and components.
  • Carrying out all complex of construction and installation works, as well as providing of start-up and commissioning works, training of personnel and setting up of stations in operational mode.
  • Support of procedures for obtaining permission to connect a solar power plant to the general grid for the implementation of electricity for green tariffs.
  • Comprehensive maintenance of the solar station, monitoring the serviceability and productivity of all key units of the facility.

The main phases of the implementation of a typical PV project, from the establishment of a preliminary feasibility study to the commissioning of the plant, are presented in the diagram:


Work of on-grid solar power plants for own consumption

Solar power stations may also be intended for generating electricity for further use in the internal electricity grid of objects of any destination: residential buildings, industrial or office premises, store or warehouses, shops and entertainment complexes, gas stations, etc. The power plant of this type varies depending on the installation – ground (both in the immediate vicinity and some distant objects) or the roof option, fastening on the facade, etc. In order to ensure complete energy autonomy of the facility and reserve the power, it is possible to install a system of energy accumulation (storage batteries), as well as software that controls the process of accumulation and optimal use of stored energy.


Such power systems do not require the use of additional sources of energy or fuel, which makes it possible to save significantly by giving up external power supply.

Avenston is a real long-term working experience in the Ukrainian solar energy market! If you have ideas and a desire to build a solar power plant in Ukraine – we are ready tolive them out!
