Conclusions The renovation of a historic tenement home in Poznan (Poland) is planned in the near future. Certainly one of the main assumptions of your project is the use of renewable power sources in order to cut down the demand for primary energy. The objective of this analysis was to compare two solar radiation conversion systems, either of which may be installed on a selected portion in the roof of this old developing. The roof faced south and inclined at an angle of 30 . It was assumed that the first program consisting of thermal solar collectors having a gross area of 51.36 m2 was employed to assistance DHW heating. Photovoltaic panels of a total active region of 50.4 m2 were the second technique that was compared. Analysis with the results of pc simulations created using the DesignBuilder application, showed that the use of solar panels permitted a saving of 24,097 kWh of thermal energy per year and 6860 kWh electricity in the case of PV panels. Final power savings had been referred to key energy savings and we obtained the following values: 17,150 kWh for PV technique and 31,326 kWh for SDHW technique. The customer can achieve an average of three instances larger final energy savings from the use of solar thermal collectors than photovoltaic panels, and this is independent of place. This worth is on average 1.six times higher when analysing principal energy savings. Even so, it must be pointed out that electrical energy is undoubtedly much more universal than thermal energy on the subject of utilizing it in all household applications. On the other hand, the advantage of thermal power is its low price of accumulation in water storage tanks. A simplified economic evaluation showed that the annual financial savings resulting from the operation of PV panels and STC technique, could be EUR 1022 and EUR 754, respectively. These are not higher values, but the upcoming surge in power rates may perhaps considerably enhance these earnings. The location, or rather the climatic circumstances, have a great influence around the performance of RES systems. Primarily based on the simulation outcomes, it was confirmed that within a cold climatic zone, the EGF Proteins Source efficiency of PV panels increases because of the reduced ambient temperature, as well as a warm climatic zone increases the efficiency of thermal solar collectors for the reason that the heat losses of those devices are lower. An option solution for the widespread photovoltaic and SDHW systems is usually a hybrid solution that combines both constructions in a single device. The simulation results showed that the PVT collector beneath consideration produces significantly much less thermal energy than traditional thermal collectors. A positive function of this solution is the improve in electricity production.
