SOLAR BATTERIES AS AN ELEMENT OF DESIGN OF MODERN ENERGY EFFICIENT BUILDINGS

Abstract

The concept of increasing the energy efficiency of buildings by placing solar panels on their facades is considered. This solution is evaluated from the point of view of modern urban design, and the possibilities of increasing the energy efficiency of lighting systems of modern buildings with the use of solar panels for their power supply are determined. The implementation of a combination of power from renewable energy sources and from the stationary grid in the absence of energy storage systems (batteries) allows to create systems capable of using almost all the electricity generated by an alternative energy source. In this case, energy losses to energy transportation will be minimal. The absence of such battery systems in the designs allows to install only the design-calculated number of solar panels without the need to make a significant backup of generating capacity for its accumulation or operation in adverse weather conditions. An additional advantage of abandoning energy storage - batteries, is a significant reduction in the use of environmentally hazardous substances such as lead, lithium and acidic or alkaline electrolytes, the production of which has a negative impact on the environment, and their disposal requires additional costs. In the work, it is proposed to use cassette facade systems with built-in solar panels, which allow architects to create a modern appearance of buildings and structures. It is shown that in the absence of solar tracking systems, the reduction in generation is 23% for the case of horizontal expansion of solar panels compared to the case of the optimal angle (for Kyiv 40o) and 40% for the case of vertical installation of solar panels. The analysis indicates the possibility of creating a modern energy-efficient design of building facades, both in the design of modern buildings and in the restoration of facades of existing buildings.
