PVT Collectors
powered by 
Our PVT collectors combine solar power and solar heat generation in a single module. Maximum efficiency, minimal space requirements – the perfect solution for your energy transition.
SETTING GLOBAL STANDARDS
GREENoneTEC is the global market leader in the production of thermal solar collectors, mounting systems as well as large-area collectors and systems.
PVT Collectors – the new technology
The company has been shaping the solar market for over 30 years and is launching another solar technology with its PVT collectors to further advance energy independence.
The owner-managed solar pioneer is already exporting to more than 119 countries worldwide.
PVT Systems are TWICE AS SUSTAINABLE
Electricity, Heat and Cooling combined.
Photovoltaics
Sunlight is converted into electrical energy with the help of semiconductor cells.
On hot days, the module heats up to 80°C. A thermal collector mounted on the back cools the solar cells and therefore increases the electricity yield.
Thermal unit
Solar collectors are required to convert solar energy into heat. Through symbiosis with solar thermal energy, the resulting waste heat can be discharged and transformed into usable heat by the heat exchanger. Two different variants are available, depending on the application. They differ in the design of the thermal component.
Twice as strong – Twice as sustainable
Electricity, heat, and cooling in one.
PVT is an innovative system that provides two forms of energy on a single surface while simultaneously enabling higher overall efficiency. With the PVT collectors, you gain numerous benefits:
Significant reduction in operating costs
Free unlimited use of energy source
Increase heat pump performance to above COP 5
Standardised components
Simple Installation – Plug & Play
No more complex geothermal probes/deep drilling
Heat pump function for defrosting PV
Future Technology that speaks for itself
Households in Northern and Central Europe use 80% of their energy for heating. The combination of photovoltaics and solar thermal energy in conjunction with a heat pump results in significant savings in operational management. More efficient use of solar energy is not possible at present.
Optimised heating of heat pumps
The use of PVT collectors enables more efficient operation of heat pumps and regeneration of geothermal probes.
PV*T provides highly sustainable solutions for new buildings with low energy requirements and for renovations, as it reduces energy consumption and increases the efficiency of heat pumps.
PVT VARIANTS
for many applications
Retrofitting PV
Existing PV modules can be retrofitted with the PV*T FLEX thermal component, which is compatible with all common module sizes and mounting systems.
PV
Component
- Free choice of modules (1722 × 1134 × 30 mm)

Questions
& Answers
What is a PVT collector?
The PVT collector combines solar and photovoltaic technology – i.e. it is a photovoltaic-thermal solar collector. The PV part generates electricity from the sun and the *T part (= heat exchanger) behind it utilises the ambient air to generate heat.
PVT collectors can therefore also work at night and in winter, which means that in combination with brine/water heat pumps, they can provide the heating required all year round. This is made possible by the heat exchanger on the back, the *T part, which is used as a source for the brine/water heat pump.
What advantages does PV*T offer compared to individual PV systems?
Double the energy on one surface – ideal for limited roof or open spaces.
Higher efficiency – active cooling of the PV cells can increase their efficiency.
Cost savings – savings through efficiency advantages in utilisation with brine/water heat pumps, no geothermal probes are required – PV*T is used as a source.
Sustainability – Reduced CO₂ emissions and environmentally friendly energy generation.
Where can PVT Systems be used?
- Single and multi-family houses
- Commercial and industrial buildings
- Hotels, hospitals and public institutions
- Agriculture (e.g. for hot water in stables etc.)
In principle, wherever energy such as electricity and heat is required.
How long is the lifetime of a PVT system?
The service life is generally 25+ years for the PV component and 20+ years for the thermal unit, depending on professional maintenance.
How time-consuming is the installation?
Installation is similar to a PV system, but requires an additional connection to the source circuit. PV*T systems save space and reduce installation costs compared to separate systems.
Can PV*T replace conventional geothermal probes such as boreholes?
PVT collectors are used for precisely this application. There is no need for expensive geothermal probes, or the high drilling costs are saved.
If you already have existing geothermal probes, you can regenerate them with the PVT collectors and thus extend the service life of the geothermal probe.
