SolSimCC – Influence of climate change and user behaviour on solar energy systems

In SolSimCC, the effects of climate change and user behaviour on the profitability of solar energy systems (photovoltaics and solar thermal) were investigated. The results show only a minor influence of climate change on the profitability of solar plants. However, two changes significantly increase the profitability of solar thermal systems: firstly, the replacement of natural gas with more expensive biogas or syngas, and secondly, the adoption of more realistic heat consumption profiles instead of the idealised profiles often used in simulations today.
