This paper deals with the possibilities of concentration of electromagnetic radiation through Fresnel lenses. The article points out errors in the optical system and their possible solutions, which are based on the latest scientific knowledge. At present, there is a development of Concentrator photovoltaics (CPV) and high-concentration photovoltaics (HCPV) systems that make the possibility of more efficient transformation of solar energy into electrical energy. Manufacturing of photovoltaic cells differs in the co...

The paper deals with the implementation of photovoltaic system in specific extraterrestrial area. It is focused on proposal of photovoltaic system for new international space station. Authors use in the analysis knowledge of NASA (National Aeronautics and Space Administration) space researches, information about of ISS (International Space Station) and proposal of first piece of new space station situated in cislunar area (space between Earth and Moon). Analysis of space deals with finding suitable location for ne...

Today energy consumption in the world is constantly increasing and therefore using energy more effectively and reduce energy consumption has been discussed a lot more. Nowadays, trend of stimulating renewable energy production is at the forefront. In this regard, in Slovakia use of renewable energy sources for home electricity and heat generation following European Union support and the project Green to Households is developed considerably. The return on investment on these funds is indeed longer, but we should ta...
