ABSTRACT

This article presents the energy parameters of a mobile home with an autonomous power supply, designed for rural residents, farm, agricultural, fishing and beekeeping complexes, located far from the centralized energy supply, and the scheme of its general structure. In addition, the energy efficiency of the house is described as a result of the provision of electricity in a mobile home through a full solar panel.

Introduction. Today, the population of the whole world is growing sharply, and in its place, this means that it is necessary for them to create comfortable conditions, that is, to meet the demand for uninterrupted electricity for the use of modern technologies. In particular, electricity, as the world's largest consumer of organic fuel, plays an important role in the technological development of the energy sector, at the same time, in the development of the country's economic sectors. Given the fact that sunny days in southern countries are 300-320 days, it can be witnessed that there are enough opportunities for the use of renewable energy sources, in particular, for the effective use of pyrolysis and biogas devices with a high solar potential. Electricity plays an important role in the technological development of the energy sector as the world's largest consumer of organic fuel. Because no matter how much we increase the production of electricity, if we do not regulate its consumption, it is very difficult to meet the growing demand from year to year. The increasing demand for electricity and changes in its composition require the creation of new technologies and the development of new energy carriers, which are associated with the expenditure of important resources [3,4].

Method and materials. To meet the electricity needs of energy consumers living in areas far from centralized energy supply, an autonomous energy supply based on alternative energy sources is a necessary task to create an experimental copy of a systemic mobile (mobile) home and base its parameters [5]. Therefore, the main goal of this scientific work is to conduct research on electricity consumption for a fully alternative energy source - based energy supply system mobile home, which is energy efficient in terms of the technical and economic characteristics used in practice [6]. This proposed mobile home will include 1 permanent living room, 1 kitchen, as well as a mini washroom (mini shower) in the open porch section of the home. To fully meet the electricity demand of a mobile home with an autonomous energy supply system, a solar panel is installed on the roof of the house, depending on the energy consumers. Considering that solar energy is not continuous, an inverter and controller are installed to adjust and control the battery and current in order to accumulate the energy of the radiation falling from it and use it effectively. Figure 1 below depicts the overall top view of this mobile home:

Results and discussions. Due to the increasing conditions for today's residents to live comfortably, each apartment has at least one TV, household appliances such as a washing machine and air conditioning. If we focus on the consumption shares of electricity in the average family in a rural area, their amount (in the energy saving mode) will be equal to:

Table 1.

Values

Research on the creation of such devices and their use as a source of low-power electricity shows that 285-300 kWh electricity can be obtained year-round from each square meter of surface of flat photovoltaic batteries with a useful working efficiency of 15 %. When solar photovoltaic batteries with a surface area of 1 m² are used as a source of electricity, 100-105 m³ of natural gas is saved per year. This makes it even more possible to use solar power devices [9]. Studies and accounts have shown that taking the average number of electricity consumers of a mobile home with the proposed autonomous energy supply to be 4, the amount of day-long need for them is 1.5...2 kWh, and per month-30...45 kWh. A biogas and solar-based autonomous electric power system for a mobile home with a total volume of 38 m³ will save up to 2.5 tons of conditional fuel per year. Relying on these analyzes, it can be recommended that for consumers of a mobile home with a volume of 38 m³ and a total surface of 72.5 m², the average is 1.5...2 kWh. It is possible to fully compensate for electricity consumption by installing a power solar panel [10].

Conclusion. Taking into account the above, the following conclusions can be drawn:  - it is advisable to use the use of renewable energy in areas that are not environmentally friendly, in areas that dispose of harmful waste to the environment, in the areas of socio-economic agriculture, in points where there is a need for heat and electricity, in fishing and beekeeping complexes.

- in centralized energy supply districts, the use of locally autonomous energy sources makes it possible to create a competing environment of the energy market.
