Roof solar power stations for legal entities is a reliable long-term investment, which can be effective both due to the use of the “green” tariff to sale of electricity to the grid, and by reducing own costs for the purchase of electricity from the grid when using solar electricity for own consumption.
Given the cost of a kilowatt hour for commercial enterprises and industry (and its growth dynamics), the latter option will become increasingly economically feasible, stimulating the further development of the commercial roof solar plants segment. World trends also confirm the great prospects and further growth in the number of roof solar power plants in Ukraine.
One of the key conditions for the successful implementation of the roof solar power plant project is the high-quality design of such facilities. Among the companies that are professionally engaged in the installation of solar power plants on the roofs, as well as responsibly and efficiently manage such projects — AVENSTON company. Our own project team has sufficient experience in the design of roof power plants, which is further enhanced by the presence of our own service unit. We offer turnkey services for design and installation of roof-top solar power systems on buildings and structures of any types and complexity.
Distributed power generation based on rooftop PV systems has significant advantages both from the point of view of networks and from the point of view of the whole society. Medium-sized solar power-stations are very often installed on roofs. Such mounting method has certain advantages:
Roof-mounted solar power plants have great prospects for the future even without the use of such incentive tools as the “green” tariff.
The main advantage of rooftop PV is that electricity is produced where it is consumed, and when it is needed.
For example, in summer, air conditioners work in office premises at a time when the largest flow of solar energy is observed. After the installation of a solar power station for the owner of the building in the summer, cooling and air conditioning costs are significantly reduced. It is also possible to provide reliable uninterrupted power for the building and improve the quality of power supply by additionally installing batteries, the cost of which is constantly falling.
Electricity prices continue to fluctuate from time to time, making it difficult to calculate electricity costs over a period of time. However, the price of electricity generated by a solar station can be easily determined. In fact, you can even predict the cost of generating electricity for another 10 — 20 years. That is a sound investment. Also, the operating cost of rooftop solar power plants is stable and relatively low, with minimal maintenance required.
Rooftop power plants can be installed on any type of roof. This way, people do not need to free up land or invest in buying more land to install solar panels. Besides, the panels provide additional protection for the roof of the building on which they are installed.
We offer businesses a winning solution to reduce energy costs. This is a commercial solar power plant for self-consumption. The photovoltaic system will have the best suit to load conditions of your enterprise and allow you to reduce or completely refuse to purchase electricity from the external grid. The project implements within 2-4 months, and the saving begins from the first minute of the launch of the station.
AVENSTON company performs all turnkey works up to putting the solar power plant into operation and monitoring of its work subsequently. Upon request, a client concludes an agreement with AVENSTON for Operations & Maintenance of Solar Power Plants.
Contact us, and highly professional engineers of our company will develop a project of Solar power plant for self-consumption for the existing infrastructure of your enterprise, taking into account the level and mode of consumption, the shape of the roof, free space on the ground, climate, terrain, level of insolation in the region, etc.
Work on your project will include all stages, from concept development and design to equipment delivery, construction, staff training, and commissioning of the power plant.
Ukraine located in a suitable region with a sufficient level of solar insolation for the construction of Solar power plants, even in the northern regions of the country.
In 2019, 3,537 MW of solar power was built and launched in Ukraine. The business is trying to adapt to new conditions and is actively installing photovoltaic panels on the roofs of its enterprises. Therefore, the demand for commercial Solar power plants is growing due to the development of technologies, increasing the efficiency of solar cells, reducing the cost of photovoltaic energy, and the popularization of renewable energy sources.
There are several ways to implement PV power plants for self-consumption. The installation of solar modules is possible both on the ground and on the roof (storage facilities, production shops, supermarkets, shopping and office centers, farms, hotels, etc.).
How does it work?
Installed on the roof (or on the ground) PV modules convert solar radiation into direct current. Connecting cables sent current to the inverter station. Inverters convert direct current to alternating current. In the case of an autonomous or hybrid PV-station, the intermediate stage is the conservation of excess electricity in the batteries. The electric alternating current is supplied to the consumer.

Frequently asked Questions
What should be the placement and angle of the modules?
When installing solar panels, it is important to set the correct solar azimuth. An ideal disposition is an orientation to the geographic south +/- 15%. If the panels are installed on the ground, it is not a problem to set the angle. But for rooftop solar stations, it is more difficult to fulfill. If the roof slope is not oriented exactly south, an angle deviation of up to 30% is allowed. In this case, a decrease in efficiency of about 6% is possible.
Since the Earth revolves around the Sun, its location in the sky changes both during a day and throughout the year. To maintain the maximum efficiency of solar modules, they install on mobile trackers, allowing them to change the angle to the optimum. But in most cases, a fixed group of modules is positioned at a fixed angle of 25-35 degrees.
In the case of a mobile system, the slope of the modules changes twice a year by 10-15 degrees decreases/increases in the summer/winter.
Also, when a commercial rooftop solar power plant installing, it takes into account the natural slope of the roof slope towards the horizon. If the roof is too flat or, conversely, has a strong slope, special fastenings and brackets are used.
What is the economics of PV power plants for self-consumption?
The payback and profitability of a solar power plant are individual parameters for each project and depend on several factors. The main ones are the insolation level and the station purpose. For example, solar power plants for the “green tariff” in the west and north of the country pay off in 7-8 years, while autonomous stations in these regions pay off for more than 10 years. In the southern regions of Ukraine, projects of commercial solar power plants pay off in 3-4 years.
The cost of the station is approximately calculated from $ 660 per kW and depends on the equipment chosen, the necessary preparatory and construction work, and the individual needs of the client.
How to install a solar power plant for self-consumption, what is need for this?
