Prefab PVT roof elements operational at SolarBEAT

Within the innovation project “PVT inSHaPe”, the company Solartech installed two prefab PVT elements on the SEAC  research facility SolarBEAT. These PVT elements generate both solar heat and solar electricity from the same roof area. In the PVT inSHaPe project, we investigate the use of these elements in combination with a heat pump for space heating and domestic hot water. The goal is to generate options for realizing (near) zero energy buildings. In total three different PVT systems will be built and their performance will be evaluated.

The roof elements are prefab produced in the factory, minimizing the installation time on the roof. In this concept, the PVT system and roof isolation are part of a single constructive element. These elements are put in place using a crane.

SEAC presents a new market survey of PVT products

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.
