FAQ

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.

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

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.

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.

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.

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 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

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.

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)
