Teaching Renewable Energy Systems by use of Simulation Software

Experience in using simulation software for teaching solar energy and heat pump applications are presented at the Eurosun 2016 conference. The authors discuss suitable didactic concepts specifically developed for teaching renewable energy and energy efficiency topics. Two main advantages of applying simulation software in solar education are identified: 1) simulation can provide an understanding of data that is otherwise not accessible (e.g. cumulated operating hours and number of starts of a heat pump depending on control strategy); 2) use of simulation software in teaching have a positive influence on the motivation and attitude of the students….

Fast simulation algorithm for PV self-consumption with heat pump systems

Self-sufficiency of systems with photovoltaic (PV) energy production gets more and more important. Demand side management with the use of heat pump and thermal energy storage has proven to be an efficient and effective means for increasing the PV self-consumption ratio. Accurate prediction of the self-consumption and the resulting self-sufficiency quota requires a comprehensive simulation including heat pump characteristics, thermal balance of the building and hot water demand profiles. These simulations are usually elaborate and time consuming. This work presents a fast but reliable estimate of the system’s PV self-consumption potential…

SOLNET - PHD-Scholarships and courses on solar heating

The scolarshop project “SHINE” was launched in autumn 2013 in the frame work of the Marie Curie program of the European Union (Initial Training Network, ITN). 13 PhD-scholarships on solar district heating, solar heat for industrial processes, as well as sorption stores and materials are carried out in this framework, one of which is hosted at Vela Solaris. The program is the continuation of the famous SolNet Network that has been coordinated by the Institute of Thermal Engineering at Kassel University, Germany. The network offers PhD courses on solar heating and cooling, conference-accompanying Master courses, placements of internships, and PhD scholarship projects….

Evaluation of a high temperature solar thermal seasonal borehole storage

A district combined solar system with a seasonal borehole storage was put in operation for the residential area Anneberg, Stockholm, in 2002. Since then a number of system studies were performed. The studies show that the system has much lower performance than was expected during system design. This paper presents the evaluation as well as the analysis of the system performance, when the borehole storage has reached a quasi-steady state….

Accuracy analysis of software for the estimation and planning of photovoltaic installations

As the use of photovoltaics expands, with more and more commercial and residential users investing on solar energy systems around the globe, there is substantial demand for relatively simple, easy-to-use software packages for the planning and performance estimation of photovoltaic installations by installers and architects. In this paper, the calculative accuracy of TRNSYS, Archelios, Polysun, PVSyst, PV*SOL and PVGIS is being examined in comparison to the real electrical energy generated by a grid-connected 19.8kWp photovoltaic installation. …
