Calculation of the amount of produced electricity by photovoltic panels / Marek Kušnír, Peter Kapalo // Геодезія, архітектура та будівництво : матеріали IV Міжнародної конференції молодих вчених GAC-2011, 24–26 листопада 2011 р., Україна, Львів / Національний університет "Львівська політехніка". – Львів : Видавництво Львівської політехніки, 2011. – С. 24–25. – (3-й Міжнародний молодіжний фестиваль науки "Litteris et Artibus"). – Bibliography: 3 titles.https://ena.lpnu.ua/handle/ntb/19263Nowadays, when the amount of exhaustible energy resources in the world are reducing and their prices are increasing proportionately, mankind tries to find alternative sources of energy. Use of solar radiation has huge potential in the future. Already today, the sunlight is transformed into heat or electric energy. For the conversion of solar energy into electricity we are using photovoltic cells. The Slovak Republic is in the use of photovoltaic systems on the tail in the European Union. Electricity produced by photovoltaic panels can then be used to drive pumps in the heating or cooling systems. In this article we focus on the interaction between the photovoltaic system under certain weather conditions in the city of Kosice in Slovakia. A closer look at how weather affects the efficiency of photovoltaic panels.enphotovoltic systemsolar energyrenewable energy sourceArticle
