Solarus at home
Are you looking to provide your home with heat, hot water, and electricity in a sustainable way? The PVT panel presents an attractive solution that is a step-change to making your home gas-free.
Installing one or more PVT panels on your roof, you not only generate power, but you can also use the heat. So, you can get maximum return from the sun and your roof.
PVT stands for Photo Voltaic Thermal. A PVT panel looks like a solar panel and has PV cells at the front that convert sunlight into electricity, and it has an integrated heat exchanger that generates heat. The heat can be used to heat tap water. The electricity you generate can be used for your household needs, and, if have you have any left over, it can be returned to the grid.
"The most cost-effective panel under the sun."
A PVT panel can reduce both your CO2 emissions and your gas use. It converts 89% of the energy into electricity and provides hot water temperatures up to 85° C. A great return from your roof!
The panel side is connected to the meter cupboard via an inverter, just as with regular solar panels. The heat exchanger in the panel is connected to a boiler where the hot water is stored. This water can be used as tap water for washing up and bathing.
PVT panels are excellent to combine with a heat pump. The power generated by the panel can be used to charge the heat pump and the heat pump provides the heating of your home. This way you take care of electricity, heating and hot water.
Depending on your requirements, usage needs, and size of family, there are several packages to choose from. You can decide what best suits your needs.
An important step towards making your home more sustainable and gas-free.

Frequently asked questions (FAQ)
Yes, but as with solar panels, the yield is less due to the limited number of hours of sunshine and the lower position of the sun.
That depends on the heat demand in your home. The number of residents, the type of house, and its insulation all play a role. Our advisors are happy to help you with this.
With the correct installation, maintenance costs are virtually zero, though it is recommended to clean the panels twice a year. A circulator pump lasts ten years, while the inverters will need replacement after 20.
Depending on the package and combination chosen, we can help calculate this for you.
Roof load is 35 kg/ m2 including panel and assembly.
It lasts minimum 20 years.
The system - a combination of PVT and PV panels - can also be purchased without a heat pump. The payback period would be eight to ten years.
ISDE Grants are available for both the PVT solar boiler and the heat pump. Please visit the RVO website, where you will find all the info about how to apply. Note, applications must be made within six months of installation. https://www.rvo.nl/subsidie-en-financieringswijzer/isde/particulieren
You can also claim a VAT refund when submitting your tax return. Visit here for more information https://www.milieucentraal.nl/energie-besparen/zonnepanelen/btw-op-zonnepanelen-terugvragen/
The installer provides the complete package, including PVT solar boiler, heat pump, and PV panels.
We offer a ten-year guarantee on the panels and the factory-warranty on the other components.
A service contract can be terminated with the installer, who installs the panels and the system.
We use the APsystems YC600Y and QS1 micro-inverters.
The panels come with a frame for easy roof-mounting. It is set vertically and fits on both a flat or a sloping roof.
You can track the output of the PV installation via a web application or an app on your phone. The real-time output of the solar boiler is read on the thermal controller installed next to the circulation pump. This information is also in the installation manuals or ask your installer.
If you have any questions about the operation and maintenance of the system, please contact your installer.
The payback period of a gas-free system is typically seven to ten years but will depend on a building or home's specific heat demand.
The payback period is the time it takes to recoup the initial investment from the cost-savings gained. This cost-saving is calculated using the current energy prices for equivalent gas and electricity saved, i.e., the savings on your current energy bill. You also save on the replacement costs of a new boiler or system you are replacing.
PVT is a technology that produces both electricity, photovoltaic energy or PV, as well as heat, solar heat, thermal energy, T from the one panel. Our PVT panels get the highest efficiency from both solar heat and PV. They convert up to 89% of the radiation into usable heat and electricity. By comparison, the best solar panels only use a maximum of 20%.
It's not a case of just adding some panels to your roof. The entire system is composed of PVT panels, an inverter, a heat pump, a storage tank, an air pressure tank, and parts.
Yes, using a heat pump, it is possible to heat your house without gas and produce hot water. You get the same comfort but save on the heating costs.
If you want to take a smaller step towards making your home more sustainable, you can also consider a hybrid system. In this case, PVT panels heat the water, but you can use the boiler for a further top-up when needed, e.g., especially in winter. You maintain the same comfort, save on heating costs and extend the life of your boiler.
