Alternative energy is a promising direction both in Ukraine and the world. High-potential heat obtained from land, water, sun and wind is inexhaustible and environmentally friendly, moreover, the government encourages the use of alternative energy sources by private households. Therefore, their installation is becoming an increasingly popular service in the Ukrainian market.
We provide a full range of alternative energy services for domestic needs, helping people to obtain energy from renewable natural sources.
The complex of alternative energy services includes turnkey work and complete customer support throughout the lifetime of the system.
The work always begins with a dialogue, since it is important for professionals to understand what the client wants to get from alternative energy. Next, the need to implement certain solutions is analyzed and it is concluded what it worth spending money on and what isn’t. A right approach is not to let the client pay for what he does not need, and to do it correct from an engineering and financial point of view.
Therefore, our scheme for providing a complex of services looks like this:
Clients do not need to contact other companies and disperse their attention between several performers.
A well-established interaction between managers, engineers and installation teams within one company ensures a timely high-quality project execution. And in case of problems or malfunctions, their quick elimination instead of looking for the culprit among different contractors.
In alternative energy projects, we prefer to use multiple energy sources:
Before starting the implementation of services complex, you need to understand whether it is reasonable for a particular project.
Therefore, at the initial stage, the technical characteristics of the building are assessed, all the materials used in the construction are analyzed literally “in parts”. The rationality of introducing alternative energy sources depends on their quality.
The heat calculation includes the analysis of walls, foundations, floors, roofs, windows and other components from which the house is built. Engineers calculate how much cold and heat penetrates directly through these structures. And then they conclude whether it is rational to use alternative energy in this house in the form of heat pumps and solar energy, or not.
When the building is not energy efficient. That is, it was built from low-quality materials – the quality of the insulated glazing leaves much to be desired, and the floor, walls and roof are poorly insulated. In such cases, the house loses a lot of heat in the cold season, and in summer, on the contrary, all the heat from the street penetrates into it. As a result, the owners spend a lot of energy on heating / cooling the air, but the house is simply not able to hold the available energy. In this case, it is absolutely inappropriate to invest in alternative energy, since it will never pay off.
It is worth implementing complex projects on alternative energy only for energy efficient buildings. They can use high-potential equipment and alternative energy in the form of a heat pump, solar collector and photovoltaics.
When the engineers are convinced of the energy efficiency of the building, they decide which type of pump to use – geothermal (powered by the earth’s energy) or air (air-water). The choice depends on the total area of the building and the rate of heat loss in the winter period.
Based on the experience, it can be said that geothermal pumps are often installed in large, if not huge, buildings. They are distinguished by large capacities, which are enough to heat large areas characterized by increased heat loss.
However, recent trends in construction show that people prefer to build small, compact homes that have little heat loss. In such homes, we recommend using air-water heat pumps.
Another fact in their favour is the climate. Now the winters are not so cold, and we can use not only geothermal pumps, taking heat from the ground, but also taking it from the air. Or, rather, using a pump to convert air into heat and send it directly to the room.
When the choice is made in favour of a heat pump, the expediency of installing a solar collector for heating water is further evaluated. Because when using a high-potential energy source (heat pump), spending thousands of dollars on the purchase and installation of solar collectors in the majority of cases is not rational.
Sometimes customers want to install a heat pump, but the budget for its installation is not enough. In this case, the task of engineers is to make all the calculations and carry out installation work as if it were a heat pump, but on the condition that it will be installed later.
That is, the work is being carried out for the future, and alternative energy sources are introduced when the funds are available.
In this case, the main source will be an electric boiler in the boiler room, and a solar collector will be an auxiliary element for hot water supply. From March until the end of October, it will heat the water, and all excess heat energy will be directed and accumulated in the buffer tank.
Additionally, heat transfer equipment will be connected: under floor heating (used together with low-temperature heat sources – heat pumps), fan coil units, floor convectors, radiators.
Under floor heating serves for comfort and gives a certain warmth at an outside temperature, for example, down to -7°C. However, it cannot quickly respond to external temperature changes and fully heat the room, as it heats up to a maximum of 26°C (so as not to disturb the resident’s comfort). Therefore, when the outside temperature drops below -7°C, radiators, fan coil units and floor convectors turn on. It is they which quickly react to the microclimate outside and quickly give off heat, allowing you to maintain a stable temperature in the premises (for example, + 22°C).
When all the ducts are laid at the stage of house construction, the heat pump can be installed at any time as soon as the client is ready. To do this, it is enough to remove the electric boiler and hang up the heat pump as a highly efficient source of energy.
It is used together with a gas condensing boiler in the event that the house is highly efficient, but the owner, for some reason, is against installing a heat pump.
The gas condensing boiler heats the house and provides hot water during the cold season. The solar collector is put into operation in March and supplies the house with solar heat until the end of September. Thus, this equipment works in conjunction.
Despite the availability of fully functional sources of alternative energy, private homes are still dependent on central energy supply. And when buying a plot, it is important to pay attention to this fact.
Our task is to anticipate power outages in advance and prevent any inconveniences associated with it. Household appliances should still work properly, pumps should provide heat to the boiler room. The house must “live” for some time without electricity. This is possible with the help of an uninterruptible power supply (UPS), in our case it can be a solar power plant, which is compensated for by feeding through a photo module. Please note that by installing a permanent source of electricity, the equipment in the house has to be energy efficient.
A crucial point is that the engineers of “Solovei” company DO NOT MAKE uninterruptible power supply sources for complete autonomy from solar energy for 2 reasons:
1. Short period of solar activity.
In Ukraine, it lasts from March to November.
Solar energy is too dependent on the weather: in cloudy or rainy weather, you cannot take electricity. Building a large power plant to compensate for the needs of electricity and stocking up on batteries are very expensive.
2. Considerable expenses for equipment
For complete autonomy, you will need:
Wind turbines are not only noisy, but also inefficient in some places due to different wind potential.
To calculate their efficiency as an energy source, a meteorological station, analysing the wind indicators for a year, is first set up on the site. And only in a year (!) it is possible to say whether it is advisable to install a wind farm or not.
You also need to understand that without a wind generator, it is almost impossible to provide a house with electricity during the period from September to March in our country, mainly from the viewpoint of economy.

This section includes equipment for the supply of electricity, hot water and swimming pool water heating in non-traditional way, namely, through the use of solar energy, soil, air or water. This subject is very interesting and underdeveloped, but the demand for such systems is gaining stunning speed. If you wisely pick up such system, you can not only provide electricity to your home, but also earn money by selling energy in the network on a green tariff.
