TECHNICAL METHOD OF CALCULATING POWER OF SOLAR POWER PLANTS IN TROPICAL CLIMATES AS IN THE REPUBLIC OF BURUNDI

Developed a technical method for calculating power of an autonomous solar power station (ASPS) and its elements in a tropical climate, which allows to take into account the changing load during the day and thus accurately determine the required capacity of the battery (batteries) and eliminate the unreasonable exaggeration of the power of the power station elements and an increase in the cost of this ASPS. To design ASPS, it will be necessary to determine the nominal power of the solar modules, their number, the battery capacity, the power of the charge-discharge controller and the inverter. In this case, important parameters for calculating the power of ASES are: location area, total area of the house, the number of rooms, used electrical appliances, the presence of hot water and heating; the total maximum power of all electrical appliances, the approximate working time of electrical appliances. These problems in the available literature are not fully reflected, namely, in a tropical climate like in the Republic of Burundi are completely absent, therefore the development of a method for calculating power of the ASPS and its elements is a relevant issue. The purpose of this research is to develop a method for calculating power of the ASPS under tropical conditions as in the Republic of Burundi, which is divided into seven basic steps for ease of presentation.
