Conclusions The renovation of a historic tenement home in Poznan (Poland) is planned in the close to future. One of the key assumptions on the project could be the use of renewable power sources in order to lessen the demand for primary power. The objective of this evaluation was to evaluate two solar radiation conversion systems, either of which may very well be installed on a chosen element of your roof of this old building. The roof faced south and inclined at an angle of 30 . It was assumed that the initial AS-0141 CDK program consisting of thermal solar collectors having a gross area of 51.36 m2 was applied to support DHW heating. Photovoltaic panels of a total active region of 50.four m2 were the second program that was compared. Analysis in the benefits of computer system simulations created with all the DesignBuilder application, showed that the usage of solar panels allowed a saving of 24,097 kWh of thermal power per year and 6860 kWh electricity in the case of PV panels. Final energy savings had been referred to major power savings and we obtained the following values: 17,150 kWh for PV system and 31,326 kWh for SDHW system. The consumer can obtain an typical of three occasions larger final energy savings in the use of solar thermal collectors than photovoltaic panels, and this really is independent of location. This worth is on typical 1.six instances higher when analysing principal power savings. On the other hand, it needs to be pointed out that electrical energy is unquestionably extra universal than thermal energy on the subject of making use of it in all household applications. However, the advantage of thermal energy is its low expense of accumulation in water storage tanks. A simplified financial analysis showed that the annual economic savings resulting in the operation of PV panels and STC system, could be EUR 1022 and EUR 754, respectively. They are not high values, however the upcoming surge in power prices could considerably raise these earnings. The place, or rather the climatic situations, possess a fantastic influence around the performance of RES systems. Primarily based on the simulation results, it was confirmed that inside a cold climatic zone, the efficiency of PV panels increases due to the reduced ambient temperature, as well as a warm climatic zone increases the efficiency of thermal solar collectors simply because the heat losses of those devices are decrease. An alternative remedy to the widespread photovoltaic and SDHW systems could be a hybrid option that combines each constructions in 1 device. The simulation outcomes showed that the PVT collector under consideration produces considerably much less thermal power than standard thermal collectors. A positive feature of this answer will be the improve in electrical energy production.
