Renovations, heritage and volumes
For your renovation projects in Grenchen, the official RegBL figures provide essential insights despite partial data coverage. With 4 buildings listed under heritage protection, it is crucial to contact the municipality early to navigate permit requirements. The median building volume of 755 m3, derived from a limited set of 4 measurements, helps define the scale for your insulation or heating upgrade plans. Since renovation years are not recorded and volumetric data is sparse, conducting an on-site assessment remains a necessary step to ensure your renovation budget and planning are accurate and reflective of your specific property.

Frequently asked questions
Are solar panels profitable in Grenchen?
Profitability depends heavily on your self-consumption rate. By using a maximum of the electricity produced by your own panels, you reduce purchases from the public grid, which significantly improves the return on investment for your residential solar installation.
What support is available for solar?
There is a federal one-off remuneration managed by Pronovo. This support mechanism helps reduce the initial investment cost. It is recommended to check the current conditions on the official Pronovo website to optimize your renovation budget.
Do I need a permit to install solar panels?
In Switzerland, well-integrated solar installations on roofs are often subject to a simple notification procedure. This greatly facilitates implementation, but it remains necessary to check compliance with current cantonal and local rules.
