Renovations, heritage and volumes
For your renovation plans in Therwil, the official RegBL figures provide essential guidance. With 715 buildings under heritage protection, it is vital to contact the municipality early to discuss permit requirements. Regarding building volume, the median is 782.5 m3. However, please note that this figure is based on only 16 properties measured according to the SIA 416 standard, while 1894 properties use other standards or are categorized as unknown. Consequently, data coverage for volume is partial. Furthermore, no specific data regarding the renovation year is recorded, which should be considered during your project assessment.

The benefits of solar energy
Switching to solar power makes you more independent from the public grid. By producing your own energy, you protect your budget against future price increases. Profitability depends mainly on how much power you use on site.
By using household appliances during sunny hours, you maximize your savings.
RenoIndex supports you in this process by providing a precise price range for your installation, allowing you to calculate your future return on investment with greater peace of mind and better visibility regarding the costs involved.
Financial aid and subsidies
It is crucial to inquire about these subsidies before starting the work. By using RenoIndex, you can get a clear overview of the total costs, which facilitates your administrative tasks.
Keep in mind that federal aid is accessible to all eligible Swiss owners, even if no specific municipal rules are mentioned for Therwil.
Regulations and procedures
Before starting, ensure you comply with safety standards and technical requirements. To estimate the costs of the installation, do not hesitate to use our RenoIndex estimator, which will provide you with a reliable price range.
Thorough planning from the start avoids unpleasant surprises and ensures your project complies with current technical and administrative expectations.
Choosing the right equipment
The choice of equipment directly influences the durability and efficiency of your energy production. There are several panel technologies, each with its own specificities.
It is recommended to compare several quotes from qualified installers to get the best value for money. Use RenoIndex to define your initial budget. A well-sized system, taking into account your actual consumption, is key to a successful investment.
Do not forget to include the costs of any battery storage systems if you wish to increase your energy autonomy, especially at night when solar production is zero.
