Cost analysis for Construction of Photovoltaic Roofing

Abstract

The article deals with roof building structures that allow the use of solar energy in the segment of family houses. Modern technologies include photovoltaic roofing, which, in addition to the production of electricity, also fully replaces the roofing itself. It does not disturb the resulting aesthetic and architectural impression of the roof. The article analyzes the cost, return on investment and service life of four solar solutions that are applied to the roof structure of a family house. The use of solar energy is currently small in the segment of family houses in Slovakia despite state subsidies. As this is an ecological way of obtaining energy, there is a need for more discussion on this topic in order to ensure the sustainability of the planet.
