Avenston builds solar PV power plants of various types. One of the main areas of our activity is general contracting for the construction of commercial on-grid solar power plants (EPC contract). The Avenston group of companies has extensive experience in implementing projects of this type, is highly qualified and possesses the necessary experience and knowledge. We carry out all the necessary stages: we carefully prepare and plan the project at the stage of collecting initial information and obtaining permits, we are engaged in technical modeling and design of the future solar power plant, we supply a complete set of equipment and materials to the construction site, we carry out all construction and electrical work, we are engaged in connecting to grids, commissioning of the facility, as well as its subsequent maintenance.
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.
Solar energy, which hits the surface of the Earth, has a colossal power – solar radiation for a week surpasses all the currently known world reserves of fossil oil, uranium and coal combined. Solar panels (photovoltaic modules) convert the energy of solar radiation into alternating current, which is then fed to the power grid. Grid (that is, connecting to tte grid, on-grid) solar photovoltaic systems can be used both to generate environmentally friendly electricity for the purpose of further sale to the grid at a green tariff, and to generate electricity for own consumption.
On-grid solar power plants are one of the most common types of photovoltaic systems designed to generate electricity with its subsequent transfer to the external grid. Most often, the electricity generated by a grid-on solar power plant is sold to a third-party buyer, for example, by a “green” tariff, a market price or a price set in a special “green” auction. On-grid solar power plants are divided by their design into ground, rooftop and facade. They can use either a fixed placement of solar panels, or use moving support structures that allow the surface of the solar panels to be oriented in the most optimal direction in relation to the sun. On-grid solar power plants can also be divided into large industrial (average power up to 1 MW and more powerful – from 1 MW) and smaller private (usually their capacity does not exceed several tens of kilowatts).
On-grid photovoltaic power system consists of the following components:
Avenston provides 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:
Middle-size commercial solar power plants are stations with a capacity of 50 kW to 1 MW. The area of such solar installations depends on the number of solar modules and ranges from approximately 300 m2 to 1 ha. The comparatively small size of the power plant makes it possible to achieve the optimum solar panels location according to cardinal points. When choosing the size of a solar station, it is important to consider how much electricity the future facility must generate to meet the project’s objectives. Avenston offers any services to design and build solar power plants of such size or type.
Ground-based on-grid solar PV power-stations are widely used to build a reasonably productive photovoltaic system and generate revenue from the sale of electricity. The most often used location option for commercial solar power-stations is a land surface installation of all elements of a photovoltaic station (solar batteries, mounting systems, inverters, transformers, and other equipment parts). Advantages of ground placing of a solar power-station:
From one side, such method of equipment placing makes a solar power-station project to be a bit longer on the whole, because it is necessary to elaborate all formal questions related to a land lot. On the other hand, the undoubted advantage of surface solar power-stations is the possibility to install greater (as compared to roof options) amount of solar batteries, in other words, the possibility to construct more powerful solar power-stations. The payback periods depend on the efficiency of the equipment selected, the level of insolation in the region and the location of the panels. The approximate repayment period for investments in the medium-sized PV power-stations is 3.5-4 years.
Solar power plants are one of the key and many times approved competencies for companies belonging to the Avenston group. We provide all necessary services for solar energy projects, starting from the support of the development or pre engineering stages to maintenance of already built photovoltaic power plants or systems. All stages of the implementation of such projects are carried out by us independently or with the involvement of selected partners. In the second case, all key processes are managed and controlled by Avenston’s in-house project managers. List of our solar projects includes a large number of designed and built industrial solar PV power plants and on-grid commercial solar power plants. If you have plans to build your own solar power plant of any type and size, please contact Avenston. We will be happy to help you implement your project in the most optimal way.
