Description
Today, the Russian agriculture is facing food market saturation task by domestic quality products in sufficient quantities for the needs of the population. At the same time healthy nutriment is provided, according to doctors and scientists, by vegetables, which must be present in the diet of a healthy person. In this regard, a big role is assigned to the covered ground crop production, normal functioning of which allows to supply shops and markets with vegetables throughout the year. For the formation of the necessary environment inside the greenhouse promoting normal plants growth, the main role is played by the solar radiation penetrating into the greenhouse through the transparent enclosure and creating necessary light and temperature and humidity regime. Comparison and analysis of the main cover and light-transmitting materials (film, glass, polycarbonate) characteristics revealed polycarbonate to be the basic material today, light transmitting characteristics study of which this article deals with. As a research method, molecular optical spectroscopy was applied. In order to study there has been selected waveband with their length value from the 610 to 700 nm, which spans exactly the shortwave part of the solar radiation spectrum, which is necessary for the proper implementation of the plants photosynthesis in artificial rearing conditions. After analyzing the measurements results it can be said that studied "KARBOGLASS AGRO" polycarbonate samples, despite the substantially greater thickness in comparison with for example plastic film that is widely used in the old fashioned way, are characterized by higher value of light-transmitting ability for light wavelength values passing through the material - respectively of 79-80,4% and 75,4-77%. Light transmission of "KARBOGLASS AGRO" cellular polycarbonate is at 5 ± 1% higher than of other traditional materials. Among the studied coating materials for covered ground facilities and due to the research results of their light-transmitting capacity, today cellular polycarbonate is of undoubted advantage

Description
In the context of implementing programs on reducing budget expenditures for the social sphere utilities, it is urgent to intrude renewable energy sources into the practice of their energy supply. However, despite all their diversity, not all constructions based on renewable energy sources can be used under conditions of urban development. Besides, the mutable nature of the solar radiation coming on the Earth's surface requires specific forecasts and calculations of its intensity. Accurate estimation of the area solar energy potential of the generating plant proposed location allows not only to justify its parameters at the design stage, but also to predict its operating mode and to evaluate its technical and economic efficiency. The purpose of the article is to estimate the level of solar radiation for Volzhsky, Volgograd Region, at the initial stage of designing and justifying the implementation of power plants transforming renewable solar energy in urban areas. In the article, it is proposed to apply method for estimating the solar energy potential of at a specific geographic point, based on a combination of the calculation method for determining the solar radiation characteristics and actinometric measurements. Volzhsky of the Volgograd Region, like most settlements in the Lower Volga region, has a high solar energy potential: 1228.8 kWh / m² for the horizontal surface of the southern orientation of the receiving surface of power plants, which can be increased by 16.2% at its optimal orientation relative to the horizon and the sides of the world. However, the expansion of the utilization of the solar energy potential of the district may be limited to the location of the existing buildings and structures at which power plants may be located in urban development conditions
