F.A.Q

Photovoltaic systems draw energy from the sun and convert it directly into electricity. In contrast to conventional power plants such as a coal-fired power plant, they do not emit any climate-impacting CO2 and are therefore 100% climate-neutral.

A photovoltaic system gives you and your environment many advantages, such as reducing your electricity costs, protecting the environment with self-produced green electricity, making yourself independent of rising electricity prices and securing long-term returns thanks to attractive feed-in tariffs

Most German roof constructions are statically suitable for the installation of a photovoltaic system. Despite this, we check whether your roof is suitable for this.

- The remuneration for solar power from new PV systems increased in July 2022 - for self-consumers as well as full feeders

- If you want to buy a photovoltaic system and battery storage, you can get low-interest loans and grants

- Nationwide you are entitled to the feed-in tariff for solar power that you feed into the public grid. For systems with an output of up to 10 kilowatts that go into operation after July 29, 2022, you will receive 8.2 cents per kilowatt hour. The grid operator pays you the respective rate for your electricity for 20 years.

- You can apply for a loan to finance a PV system alone, including battery storage, or just for battery storage. In addition to the pure acquisition costs, the costs for planning, project planning and installation of the system are also subsidised

PV systems can easily be installed on flat roofs. In this case, the modules are set up at an angle using a mounting system so that they are optimally south-facing and have a favorable inclination. At the same time, the inclined installation of the modules ensures the cleaning effect and adequate ventilation.

The amount of solar power generated depends on the location, the inclination and orientation and the solar modules used. On average, a photovoltaic system in Germany generates around 1,000 kilowatt hours of electricity per kWp, with the electricity yield in southern Germany often being slightly higher than in northern Germany

Photovoltaics have proven their reliability over many years and in many different applications. Photovoltaics have been used in space travel since the 1960s and had already proven themselves there. Many thousands of small and large plants have been built in Germany since the 1990s. A service life of approx. 30 years or more is currently expected

The direct current generated in the modules is converted into the usual mains alternating current via an inverter. The solar system is connected to the normal 230-volt network. The electricity generated in the photovoltaic system is used at all times, either in your own household or via the public power grid through households in the area.
 

An investment in a PV system is worthwhile, especially for self-consumption. The self-generated electricity is much cheaper than the electricity bought from the public grid. And for the electricity that is not consumed and fed into the public grid, you receive a state-guaranteed feed-in tariff for 20 years.

Photovoltaikanlage besteht aus folgenden Komponenten, die individuell aufeinander abgestimmt sind und an die baulichen Grundgegebenheiten des Hauses angepasst werden:

Solarmodule, die aus der Sonnenenergie Gleichstrom erzeugen
Wechselrichter, die den Gleichstrom in netzkompatiblen Wechselstrom umwandeln
Einspeisezähler, der den eingespeisten Strom in das Stromnetz misst
Verkabelung und Montagegestell, auf dem die Solarmodule befestigt werden
Stromspeicher (optional), der den erzeugten Solarstrom zwischenspeichert

Yes, the income from the operation of a photovoltaic system must be taken into account for tax purposes and must be reported to the responsible tax office. From the point of view of the tax office, operators of a PV system who only feed part of the self-generated electricity into the public grid are tradespeople. From a tax point of view, a PV system that produces electricity for personal use and for feeding into the public grid is a commercially used system. The owner of a property with a PV system is therefore a trader before the tax office who must pay taxes (in Germany)

With the house transfer point, the fiber optic cable enters the house. The installation location of the transfer point is within 3 meters of the building entry. This is usually installed in the basement or in the service room.

Fiber optics are especially good for long-term surfers and homeowners. Especially for the future as home office is becoming more and more of a trend

There are significantly fewer disturbances, and the promised speed also arrives on the computer or smart TV. If you depend on a stable internet connection at home, a fiber optic connection is just the thing for you. Likewise, these are the new lines for now and the future as consumption increases daily.

As with a DSL connection, you also need a router for a fiber optic house connection. The router is the connection point for all end devices that you want to connect to the Internet.

Developed exclusively for fiber optics, the FRITZ!Box 5590 Fiber and FRITZ!Box 5530 Fiber support all important fiber optic standards and connections. In general, it is important that the router is not very old for the connection to be strong

When the rooftop modules are hit by the sun's rays, they move. Since energy is always generated through movement, electricity is generated from sunlight. The conversion of light into electricity is also called the 'photo effect'. That is why solar systems are also called photovoltaic systems.
