1.) PVT modules combine the photovoltaic generation of electricity with the thermal generation of heat energy

That's right! PVT modules have an efficiency of up to 89%, while PV modules only have 21-24%. Why is that? Because PVT modules not only generate electrical energy from the sun but also up to 65% thermal energy.

2.) However, PVT modules are not powerful enough to replace the combination of PV with heat pump

Only partially true! PVT modules have an electrical output of over 400 Wp. This makes them almost as efficient as high-performance sports PV modules.

3.) In most cases, the combination of heat pumps and photovoltaics is significantly higher in overall efficiency and total energy savings than that of PVT modules.

That's wrong! When you replace a fossil-fuel heating system with a heat pump, you're replacing a heating system, not an electricity system. A heat pump requires heat from a source (ground, water, sun, or air), which is then heated to the desired flow temperature using a compressor.

In winter, when the heat pump requires electricity, PV modules have little power!

PVT modules, especially closed modules such as the ABORA aH72SK (the most effective module in the world), bring over 40° Celsius from the roof and support or even relieve the heat pump and thus the heating circuit and the hot water supply.

From April to October, the heat pump is usually unnecessary because the PVT module provides heat with almost no electricity. An 8-watt high-efficiency pump is sufficient for circulation.

4.) Expert advice is essential to find the optimal and most economical solution for you.

That's right! The installation of a heat pump must always be tailored to the individual home. This is the only way to ensure optimal and efficient heating for your home.

5.) Heat pumps only work with underfloor heating and thermal insulation.

That's wrong! A Clausius heat pump achieves a maximum flow temperature of 65° Celsius. This makes it one of the most efficient and robust heat pumps in the world.

So, before covering your house with hazardous waste (facade insulation), consider replacing one or two of your radiators. This is significantly more cost-effective and doesn't create cold spots that cause moisture in the house and thus mold!

If I heat my house with the sun, I can also heat a tent efficiently, environmentally friendly and regeneratively!

6.) Brine/water heat pumps require a borehole.

That's wrong! The term "brine" is confusing, as it's a glycol-water mixture and has nothing to do with brine. We use an environmentally friendly glycol mixture that freezes at -30° Celsius and only evaporates at +129° Celsius.

Brine heat pumps can be used with air inverters as air-to-water heat pumps. For this, we prefer the WpSat 15 from ratiotherm, which, with a sound pressure level of 35 dB, is inaudible.

Brine heat pumps can be combined with PVT modules for even greater efficiency. Due to the high thermal energy recovery, these systems consume even less electricity over the course of a year than brine heat pumps that obtain their heat from a borehole. Furthermore, PVT modules are far more cost-effective than drilling into the ground!

7.) A borehole and PVT can be combined.

Yes, that's true. You can store excess thermal energy underground in the summer, thus providing more heat in the winter. However, the ratio of PVT to ground drilling is precisely calculated by the drilling companies we use and coordinated with the relevant environmental agency.

8.) PV or PVT modules must be ideally aligned to the sun to achieve maximum performance.

That's partially true! Photovoltaics, which generate electricity from light, not the sun, requires light waves between 365 and 780 nanometers. Sun damages the module because excessive solar radiation causes it to overheat, resulting in a loss of up to 17% of its output. Incidentally, PV modules facing northeast or northwest lose just as much power in the summer as an overheated PV module.

A PVT module can cool the PV process in summer and thus ensure long-term efficiency in power generation.

9.) On a flat roof, modules must be mounted with a slope of up to 37 degrees!

That's no longer true! Recent studies from various universities have found that at a 5-degree tilt, modules lose up to 10% of their power. However, by reducing the shadow, you gain up to 30% more surface area! That's a 20% increase in efficiency!

Unfortunately, PVT is not yet known in Germany, the country of Russian gas!
