Abstract
According to European Union politics, Poland is expected to achieve at least 15% of the final energy consumption from renewable sources and to reduce 20% of greenhouse gases reduction in comparison to 1990. Among a variety of sources, (i.e. wind, biomass, geothermal, solar) energy conversion is one of the most promising solutions. The solar energy is clean and free. PV installations do not produce CO2gas to the atmosphere and can be installed to any size based on individual energy demands. Besides, the investment costs for such systems drops every year. Above mentioned reasons cause a strong interest in small photovoltaic installations, and an increasing number of energy prosumers. Selling electricity to the grid in the present renewable energy legislation is not profitable. For this reason energy produced from PV installations should be consumed directly where is produced. This paper shows the results of the computer simulations and analysis of annual, winter and summer half year energy yield of photovoltaic system for a single-family house. Following orientations were taken into account: east-west, south. Effect of tilt angle of the modules integrated with building façade was investigated. Economic and ecological aspects were analysed. DDS-Cad and PVSyst software were used for modelling and simulations.
Highlights
According to Directive 2009/28/EC of the European Parliament and of the Council of 23 April 2009 on the promotion of the use of energy from renewable sources, Poland should achieve at least 15% of the final energy consumption from renewable sources and 20% of greenhouse gases reduction compared to the 1990, by the year 2020
This paper presents the computational analysis including determination of optimum azimuth for photovoltaic installation located in Warsaw, Poland, in order to maximize the energy self-consumption of the household
Results of computational simulations show that the optimum solar azimuth for PV array located in Warsaw, capital of Poland, is 0°
Summary
According to Directive 2009/28/EC of the European Parliament and of the Council of 23 April 2009 on the promotion of the use of energy from renewable sources, Poland should achieve at least 15% of the final energy consumption from renewable sources and 20% of greenhouse gases reduction compared to the 1990, by the year 2020. One of the example solution considered in Poland in The National Renewable Energy Action Plan is to support the development of distributed renewable energy sources, such as small photovoltaic (PV) household installations. For this reason the prices of conventional energy production (i.e. coal based) become high and they will grow in the future, in a long-term perspective. The above mentioned factors are the most significant reasons to develop the renewable energy sources market and increase interest in photovoltaic systems [3]
