The market for Photovoltaic-Thermal (PVT) systems is growing. And so is the number of PVT module suppliers. In a recent market survey SEAC found 54 different PVT module types that are currently being sold. 11 of these originate from the Netherlands. Uncovered flat plate PVT collectors make up roughly 75% of the product portfolio.
SEAC identified opportunities and barriers for PVT, based on interviews with 28 stakeholders and on literature review. The main market opportunity for PVT are applications where the available roof area is the limiting factor. Then PVT offers the highest total energy harvesting (heat plus electricity).
Another market opportunity is a combination of PVT with heat pumps and the possibility to achieve a (near) zero energy building with these technologies. Compared to side by side PV and thermal modules, the more unified appearance of PVT offers a more aesthetic solution. The largest barrier for PVT applications is the complexity of the system design and its installation. Furthermore, the high upfront costs and the lack of standardization were mentioned as barriers.
