Why the Final Price is Deceptive: The Basis for Your Solar Offer Check
Many homeowners only look at the total amount, but this says little about the actual value. Often essential items are not included in the offers, leading to unexpected costs later. It is important that the offer includes all costs, such as the proper integration into the house network.
The profitability of different offers should be assessed based on the price per kilowatt-peak (kWp). Benchmark prices vary depending on the size of the system. Check if the offer clearly separates the gross price, the anticipated one-time rebate (EIV), and possible tax benefits.
Make sure the system is labeled 'turnkey'.
Checking Completeness: These Items Must Not Be Missing in Any Swiss Offer
A serious offer must detail all components. This includes modules, inverters, and the mounting system. A turnkey offer should include administrative support.
Scaffolding is often a hidden cost trap. Pay attention to the wording and chargeable items like 'Scaffold by client'. A standard-compliant facade scaffold should be firmly calculated.
The AC installation, meaning the connection to your house network, must be performed by a licensed electrical installer. Ensure that this service is included in the offer.
Components and Performance: Recognizing Quality and Evaluating Offers
A well-known name alone does not guarantee the best performance over 25 years. Each component should be specified with an exact type designation. Trust Tier-1 manufacturers.
The mounting system must be robust and tailored to the specific requirements of the site. Ask for the static calculation for your location.
Performance optimizers are useful for partial roof shading, but increase costs if there is no technical benefit for unshaded roofs.
- Glass-glass modules are more resistant to environmental influences.
- A hybrid inverter saves space and costs and allows for future storage expansion.
Warranties and Legal Matters: What Counts in the Fine Print
Many homeowners are blinded by long warranty periods. Check if dismantling and reinstallation are included in the event of a warranty claim.
Pay attention to fair payment terms. A down payment of more than 30 to 50 percent is a risk. Choose verified installers with Swiss quality.
