Baier Technik supplies and assembles photovoltaic systems in on-roof and in-roof versions. Rooftop systems are usually cheaper for existing roofs and are offered from
3 kWp.
In-roof systems are particularly interesting for new buildings, as roof tiles can be saved. PV systems are a “must have” for today’s housing subsidies.
When submitting an offer, we can send you your self-consumption and amortization calculations.
Ideally, photovoltaic systems should always be oriented to the south, since the modules are exposed to the sun for the longest time in this direction.
Deviations from the ideal orientation to the east or west are often unavoidable and do not significantly reduce the yield. In order to counteract the shorter exposure times,
the generator area is dimensioned larger, so that the desired yield is achieved.
Modules deliver the most yield when they are perpendicular to the sun. The ideal slope is also dependent on the season, as the sun is higher in summer than in winter.
The inclination angle of solar systems for hot water preparation with a degree of 20 for effective use. Sophisticated computer programs can be used to calculate the expected yield for any plant
solutions with various orientations and inclinations for the planned plant location.
Photovoltaic systems must be checked by law at appropriate intervals. Recurring inspection intervals are intended to reveal changes and abnormalities in the plant and its surroundings that
occurred after the last plant inspection. As a guideline for the plant operator is a test interval of about 3 to 5 years, depending on the environmental impact. Thus, a permanently smooth operation without any hazards can be ensured.
For photovoltaic systems with a tilt angle greater than 30 °, the pollution is low. The losses for maintenance-requiring PV modules are approx. 2-3% of the rated output. On the other hand, pollution has a faster effect at shallow angles of attack, where soiling can cause losses of up to 10%. Especially in systems on farms, the losses are usually higher when dirt settle in, for example, ventilation ducts. In these cases, an annual maintenance interval is very useful.
Telescopic poles with rotating cleaning brushes and a spraying system were developed for the maintenance of photovoltaic systems. With these telescopic poles a safe waiting on the ground is possible so that the roof does not have to be climbed.
For our customers, we can apply for and implement the state subsidy for the photovoltaic system. As a rule, the support fee depends on the size of the system.
State subsidies can not be combined with climate and energy funds. In addition, consultancy and community funding can be requested

The different various types of modules, the polycrystalline modules have come to the forefront of the market economy. The polycrystalline PV module has proven itself through the production costs,
the good quality, the high efficiency and the specific space required per kWp. Monocrystalline modules, however, are slightly higher quality.
To improve the self-used solar energy share, the self-consumption rate can be increased as follows.
- battery storage
- intelligent energy storage management
- Hot water treatment by means of heating rods and heat pumps
- Charging stations and electric filling station
- air conditioning
- Usage behavior of the plant operator
