Solar power is one of the fast-growing promising areas of renewable energy use. The article is devoted to the use of solar radiation energy in private households of Ukraine. It is noted that the amount of solar radiation is high enough to create solar power facilities throughout Ukraine. Based on the results of the research, it was found that households that have installed photovoltaic power station are fully self-sufficient in electricity and are the most energy efficient, as the surplus of environmentally clean electricity produced is sold at a "green" tariff. Based on the data of the study of the state of installation of solar power plant in private households, has been made a forecast of the development potential of this electricity sector for the period up to 2024. On the basis of the conducted research, it can be stated that the use of solar power in private households has a sufficiently large perspective to ensure which it is advisable to introduce a net-metering system in Ukraine, which includes the free sale of surplus energy produced on the market with the possibility of "taking" it from this market later.

After harvesting corn, an important question is to cultivate the soil and prepare the field for sowing another crop, because after harvesting there are root and leaf residues that need to be destroyed in time and quality, earning them in the soil. Based on the analysis of the state of the field after harvesting corn, an assessment of quantitative and qualitative indicators of surface contamination and distribution of plant residues in rows and between rows was given. This allowed us to draw conclusions about the effective method of tillage contaminated with crop residues of coarse-stemmed crops. Taking into account the biological, physico-mechanical and morphological features of corn residues (fibrousness, elasticity, stiffness), it was concluded that for grinding post-harvest corn residues it is necessary to use active working bodies with L-shaped knives that will cultivate the soil to a depth of 6-8 cm. grind stems and root parts, ensure a sufficient degree of grinding, good wrapping and mixing with the soil. However, the high energy costs of milling the soil make us look for solutions for the strip use of cutters, while ensuring continuous tillage to a given depth. According to the conclusions of these studies, a combined cultivator is proposed, which provides passive cultivation of the row spacing with folding of plant residues that are on the surface in the row zone, milling this area with cutters 20-25 cm wide. This combination will allow to qualitatively prepare the field with grinding of all plant residues with minimization of energy costs and traction performance of the tractor. The proposed design of the cultivator-shredder is protected by a patent of Ukraine.

This work is a logical continuation of the authors’ cycle of works devoted to construction of a mathematical model of the unloading process of cuttings from a slotted hopper. The purpose of the paper is a theoretical justification of the movement of an array of cuttings during gravity unloading. The article proposes consideration of the process of unloading the energy willow cuttings from the point of view of hydrodynamic multiphase systems. It is suggested to consider the set of cuttings as a pseudo-fluid consisting of two phases: discrete (cuttings) and continuous (air). Each of these phases can be considered as a continuous environment. Under such conditions, the task is reduced to consideration of the cuttings' discharge as the movement of a viscous non-contacting pseudo-liquid. Under such assumptions, the velocity field of the set of cuttings can be characterized by the Navier-Stokes equation, the solution of which will allow forming of an algorithm for building a mathematical model of the motion of such pseudo-fluid and moving to the calculation equations of the motion with initial and boundary conditions.
