INSTRUMENTAL DETERMINATION OF INSOLATION FOR CITY ODESSA

Abstract

Use of the solar installations (SI) reduces consumption of organic fuel and, respectively, anthropogenic load on the environment. Key parameter for design of SI is insolation size. The geographical position and climatic conditions of the South Ukraine are favorable for use of solar energy. Clarification of average monthly and annual amount of sunny energy falling on a horizontal surface is carried out in this article. In the analysis, data of measurements of a meteorological station of the Odessa national polytechnic university from March, 2012 till April, 2015 were used. Average daily values of insolation for every month, and also total amounts of the energy falling for every month and for all year are defined. The analysis of comparison of the received results to literary data showed that in summer months measured values of insolation exceed theoretical, in cold months measured values of insolation are slightly lower than the theoretical. The total amount of energy per year, which falls on a horizontal surface is less than 7.4% in the literature. The value of coefficient that takes into account the decline of insolation from a cloudiness is specified. The economic justification of solar installation use for hot water supply is carried out. The annual economic charges for solar installation and a boiler room on natural gas are defined. The analysis of comparison showed that at the accounting of a payment for harmful substances emissions in environment, economic charges for SI on 31% more than for boiler.
