Frequently asked questions on photovoltaics

1. What is “Photovoltaics”, “PV” or photovoltaic power plant?

A photovoltaic phenomenon converts sunlight into electricity. PV owners can generate their own energy independent of the grid, so there is no need to pay for it.

2. How long does the whole process of implementing a power plant take?

The overall length of the process is mainly influenced by the paperwork, which is in the order of several weeks to months. The installation of the power plant itself is very quick and easy. It is roughly between 1 and 2 days.

3. Who can apply for the New Green Savings subsidy?

The state subsidy New Green Savings for the purchase of a photovoltaic power plant is intended for all owners of family houses. This applies to owners of both completed buildings and new buildings under construction.

4. What is the total amount of the subsidy?
Simply put, the subsidy you will receive is 50% of the eligible project costs. However, public bodies have a different amount, here the subsidy can be up to 70%.

5. What is the lifetime of the panels?
The PV panel itself lasts around 30 years.

6. Are the panels resistant to adverse conditions?
PV panels are of course manufactured and tested to withstand harsh natural conditions such as hail. PV panels are equipped with special tempered glass.

7. Do the panels need to be maintained?
PV panels are naturally washed by rain, so there is no need for special cleaning.

8. Is it safe to install the panels on the roof?
At present, it is safe to install a photovoltaic plant on all types of roofing. It is also possible to install panels on both pitched and flat roofs.

9. How is the optimum power output of the plant selected? How does the orientation of the roof affect it?
Several factors influence the selection of the appropriate output of a photovoltaic power plant. The most important are the technical possibilities of the roof and the amount of energy consumption of the household.

10. What happens to the power plant in the event of a grid failure?
The PV plant accumulates the energy produced either to heat hot water or is stored in batteries. As long as the plant is running and its energy is being used, both systems are independent of electricity from the grid and work even during a grid failure.
