How we achieve high profitability of projects

We do not earn on equipment

We do not sell equipment and do not make money on it.

For each project we receive 7-8 proposals for each type of basic equipment. We are striving to reduce prices and better payment terms. We check the certificates and conditions of guarantees. We analyze the risks.

We monitor current equipment prices

We work with the largest sites (pvXchange, SEIA, RENVU, ENF Solar).

Every month we receive 5 reports with prices for 48 brands of equipment. We follow the offers from 8 of our partners in Europe, Asia and America.

We watch for special offers from manufacturers.

We work with local contractors

For the implementation of land, construction and installation works we select local contractor.

We control the construction - carry out the author's supervision.

We check the main components of SPS, launch stations and train staff.

We use professional software

We use special software (PVSyst, PV * SOL) and climate databases (Meteonorm, SOLARGIS and NASA-SSE) in developing Projects. We estimate work efficiency of 120 - 140 pairs of components (solar panels and inverter systems).

We achieve maximum profitability of the Project at the planning stage.

How we do itTypical scheme of Project implementation

We develop GTS (general technical solution)
GTS is a technological map of the Project that determines the composition of equipment and helps to predict the technical parameters of project (energy production, area, capacity factor and others).
We get the point of grid connection
We develop requirements and prepare a request for a connection point to the grid. We are getting the right answer. We work with failures before obtaining technical conditions for the connection, which will be beneficial for the implementation of the Project.
We develop a feasibility study and a financial model
Determine the exact composition of the equipment (based on GTS). We develop scenarios for the project implementation. We reduce the cost. We assess risks and determine methods of managing them. Feasibility study is the basis for making an investment decision.
We allocate the ground area under construction

Having determined the point of SPS grid connection, we develop requirements for the land plot for construction and draw up an application for its allocation for use.

We strive to answer and allocate the land where the cost of construction and connection to the grid will be minimal.
We develop project documentation
To obtain permission for the construction of SPS, as well as for construction and installation works and elimination of technological risks, we develop project documentation.
We get the tariff,
conclude an agreement for the purchase of electricity

We prepare the documents, include the planned SPS in the list of qualified renewable energy generators.

We sign the contract for the purchase of electricity and capacity.

This contract is a guarantee of receiving money by an investor.
We help to buy equipment
We control the delivery of equipment from the packaging to the installation place. We check the quality of supplied equipment.
We build and launch. Teach the staff
Build, install and run. We train customer's personnel.


How much does construction cost? Created using Figma

From $680 per kW of installed capacity for projects with a capacity of 10 MW.

That is, a 10 MW SPS will cost $ 6.8 million. But ...

The cost of building SPS depends on:

  • Installed power
  • Places of construction, points of connection to the grid
  • Features of the technical solution
  • Features of the land
  • Selected project implementation scheme
  • Features of the country's legislation and requirements for the localization of basic equipment

To clarify the cost of building stations, scenarios for the implementation of the Project, risk assessment and the definition of management techniques, a feasibility study is required.

Contact us and we will develop an investment proposal for you with an indication of the cost of solar plant building, based on wishes and projects features.

What licenses and permits are needed? Created using Figma

Special licenses are not required. It is only necessary that planned object be recognized as a qualified generating entity. To this end, each country has a special procedure, which takes place before the purchase of equipment and construction.

Thus, the production, operation of power plants, power grids and substations, as well as the use of RES - are not licensed activities.

Special licenses are usually required only to purchase electricity for resale.

How to deal with hailstones? Created using Figma

Even a large hail will not damage the solar power plant.

The impact of the hailstones is only on the solar panels. Design of solar panels uses tempered glass, which withstands the impact of an ice ball with a diameter of 38 mm at a speed of 25 m/s (90 km / h).

Land solar panels have been created since 1973 and were originally developed and manufactured taking into account the 25-year resource of work in the open air and taking into account the possibility of a hailstones fall.

What happens if the equipment breaks down? Created using Figma

It is highly unlikely that all equipment at the station will break down at once.

The main equipment (solar panels, inverter system, supporting structures) is covered by the manufacturer's warranty - 10 years. For an additional fee, the warranty period can be extended to 25 years.

Support structures - a set of aluminum profiles and fasteners made of stainless steel. Usually fixed structures are used that do not move, do not rust and do not break. However, they also have a 10-year warranty.

The solar panels have a sealed construction, and the diode unit has a degree of protection IP68. As the experience of operation in grid SPS showed, the active phase of which began in the 2000s, if nothing happened in the first 3 years with the solar module under load, it is unlikely that something will happen.

The inverter system is the brain of the entire solar power station. Inverters are easily amenable to repair and when performing routine maintenance they fail not more than once in 2-3 years. Chain inverters (or string-inverters) can be replaced with new ones, this takes 5-6 minutes, and the defective device is returned under warranty to the manufacturer.

How to get the land for construction? Created using Figma

There are procedures for the allocation of land for implementation of renewable energy projects.

Usually we draw up a long-term lease (up to 49 years) land plots owned by municipalities in the area that is selected for the construction of solar power station.

Since in most cases SPS are built in the distance from major cities, the cost of renting land is no more than $ 2000 per 1 hectare ($ 4 per kW of installed capacity).

What kind of administrative resource is needed? Created using Figma

Administrative resource is NOT NECESSARY.

In countries that are engaged in the development of renewable energy sources there are laws that regulate the policy of the state on the support and development of RES. Laws are supplemented by the regulations of the local Government, which establish the procedure for payments for electricity and capacity, and also determine the procedure for the implementation of RES projects.

There are norms and rules for connecting renewable generators to the grid, as well as rules and regulations for the allocation of land for their construction.

In the countries where we operate, there is an understandable and transparent procedure for obtaining a tariff.

Responsible ministries are interested in the development of renewable energy.

In addition, based on their practices, the leaders of the Regions are sympathetic to the projects for the construction of solar power plants. Similar projects create new jobs, give an influx of tax payments and raise the rating of the region. Encourage the attraction of new investments in the Region.

The main costs for the implementation of the Project are made after obtaining all necessary building permits.
