What Is PVT Solar? How Hybrid Solar Panels Work and Why They Matter in Commercial Projects

Photovoltaic-thermal (PVT) technology combines electricity generation and solar heat collection into a single panel.    This article explains how PVT works, what problems it solves, and why it is increasingly chosen for commercial and industrial buildings.

Many commercial buildings need both electricity and heat — but roof space is limited. Traditionally, developers had to choose between PV panels for electricity      or solar thermal collectors for hot water. PVT solves this conflict by delivering both from the same roof area.

1. What Does PVT Mean?

PVT stands for Photovoltaic-Thermal. A PVT panel integrates a standard photovoltaic module with a thermal absorber layer behind it.    The PV layer converts sunlight into electricity, while the thermal layer captures heat that would otherwise be lost.

Electricity + Heat from one panel

2. How Does a PVT System Work?

  • Sunlight hits the PV cells → electricity is generated.

  • Heat builds up behind the PV cells during operation.

  • The thermal absorber removes this heat and transfers it into a water or glycol loop.

  • That heat is stored or used directly for hot water, heating, or industrial processes.

Instead of losing heat to the atmosphere, PVT converts it into useful energy — increasing total solar utilization dramatically.

3. What Is PVT Used For?

SectorTypical Use
Hotels & ResortsDomestic hot water + electricity
HospitalsHot water + heating support
FactoriesProcess water preheating, drying
Commercial BuildingsHot water + partial HVAC support

4. Why Choose PVT Over PV or Solar Thermal Alone?

  • Higher total energy yield per square meter

  • Better roof utilization

  • Shorter payback in heat-intensive buildings

  • Lower CO₂ emissions

5. Is PVT More Complex?

A PVT system is slightly more complex than PV-only, because it includes a thermal loop, pumps, and heat storage.    However, for commercial buildings that already require hot water systems, this integration is technically straightforward.

When is PVT the right choice?

If your building has consistent hot water demand, limited roof space, and a long-term decarbonization target, PVT is often the most efficient solution.

Conclusion

PVT is not just a new type of panel — it is a system-level approach to maximize the value of solar energy in commercial buildings.    By delivering both electricity and heat, it aligns better with real building energy demand and often delivers stronger economic and environmental results.
