PVT Collector Design with Polysun
A PVT collector, sometimes called a hybrid solar panel, is an innovative system that combines the benefits of photovoltaics (PV) and solar thermal technology in a single component. This hybrid module generates both electricity and heat simultaneously, significantly improving area efficiency and enabling a sustainable energy supply. The unique feature of PVT modules lies in their dual functionality: while the photovoltaic component converts sunlight into electrical power, the integrated thermal collector utilizes the resulting waste heat and ambient heat for hot water production or heating support. For detailed information on the functionality and application, please also refer to the page on sizing PVT systems.
Modeling of PVT collectors, PVT modules
This type of collector consists of a combination of a solar-thermal collector and a PV module. Possible parameter alterations are identical to the components described in greater detail above. This combined-system only differs from the individual solutions in its operating features. For further details see the relevant chapter.
How large should the collector area of a PVT field be?
The optimal area depends on the desired thermal and electrical output. With Polysun, you can simulate scenarios based on load profiles, building data, and storage sizes to precisely size the required PVT area.
How does module temperature affect efficiency?
Rising temperatures reduce electrical efficiency but increase thermal output. Polysun accurately models this relationship and demonstrates how cooling via the heat circuit can improve power production.
How is integration with a heat pump simulated?
In Polysun, a PVT field can be integrated as a heat source for heat pumps. The software shows how this affects the annual performance factor (COP) and identifies the most efficient hydraulic configuration.
