Here you can find the Frequently Asked Questions (FAQ) about the solar energy register. If you do not find an answer to your question here, please contact our support.
Why is my building not included in the solar cadastre?Anchor
The solar cadastre is essentially based on an airborne point cloud and the official building footprints.
If your building is not included in the solar cadastre, it is therefore probably a fairly new building that is not yet included in the geodata used to calculate solar potentials.
It is very likely that your building will appear in the system during the next update of the solar cadastre.
When the next update of the solar cadastre will take place is mainly based on the availability of more recent point clouds. Unfortunately, such point clouds are only flown at intervals of several years. Therefore, if you are currently interested in installing a solar system, the waiting time is probably too long.
Tip: In order to nevertheless obtain a statement on the solar potential of your property, select a comparable building in the neighborhood in the solar cadastre and carry out the analysis based on this object.
How are the purchase prices for a photovoltaic system calculated in the solar cadastre?Anchor
The purchase prices for photovoltaic systems are subject to considerable fluctuations. In order to reflect the purchase prices in the best possible way, we maintain a network of installation companies and regularly request prices for various system configurations from them.
How can I individually set the purchase prices for a photovoltaic system?Anchor
You can set the purchase prices for photovoltaic systems individually in the "Module allocation" area of the economic efficiency calculator.
To do this, click on the settings icon (cogwheel) in the window at the bottom left of the application.
Does the solar register take into account the currently applicable feed-in tariff?Anchor
Yes, the solar cadastre is always kept up to date by Geoplex. New regulations of the Renewable Energy Sources Act (EEG) and the currently valid feed-in tariff are thus continuously updated.
Why is the roof overhang of my building not taken into account?Anchor
The solar cadastre is essentially based on an airborne point cloud and the official building ground plans.
Since building floor plans are used to identify buildings in the point cloud, we are unfortunately unable to take roof overhangs into account.
Can I influence the elevation of solar modules on my flat roof?Anchor
No, unfortunately that is not possible. Currently, the modules on flat roofs are always elevated towards the south, as this variant promises the highest yield per kilowatt peak (kWp).
Variants such as an elevation parallel to the roof edge or a west/east elevation cannot currently be configured.
