Abstract
Abstract. Renewable energy becomes more and more considered as energy production due to great benefits and less environmental impact then traditional energy sources. As a part of the European Union, Croatia agreed upon certain energy efficiency goal that need to be achieved during certain period. In this paper we analyse solar energy potential in northern part of Croatia, Varaždinska county. Remotely sensed data, CORINE land cover, digital elevation model, is used to perform multicriteria analysis. There are different solar panels considered: mono-crystalline silicon panels, poly-crystalline silicon panels, amorphous silicon panels, gallium arsenide panels and cadmium tellurium panels. Based on remote sensing data estimated yearly production of electric energy from solar potential could be from 8.40*107 to 2.43*1010 kWh depending on different slope of solar panels. Gallium arsenide panels shows best usability depending on slope estimated energy production is from 2.52*1010 to 7.30*1010 kW.
Highlights
Renewable energy is energy created from natural sources whose characteristic is that they are inexhaustible, i.e., they are constantly renewed in nature
The advantages of solar energy are that the conversion of solar radiation into electricity by the photovoltaic effect enables the production of renewable energy, is environmentally friendly and a reliable source of energy
If we take into consideration different solar panels, range of energy production can be calculated
Summary
Renewable energy is energy created from natural sources whose characteristic is that they are inexhaustible, i.e., they are constantly renewed in nature. Most forms of renewable energy come directly or indirectly from the Sun. The advantages of solar energy are that the conversion of solar radiation into electricity by the photovoltaic effect enables the production of renewable energy, is environmentally friendly and a reliable source of energy. (Wang et al, 2009) evaluated three different renewable energy models, but they did not include Croatia in their study. Surrounding countries such as Slovenia and Bosnia and Herzegovina resulted in total potential of 464 and 264 gigawatts respectively. In this paper we deal with the potential of solar energy in Varaždinska County and provide the amounts of energy that can be obtained by using different types of panels at three different panel inclinations
