Photovoltaic panels yes, but... stay vigilant
Since the energy crisis of 2022, the solar market in Switzerland has been booming. As a result, many unscrupulous companies are taking advantage of the situation to aggressively approach private individuals, sometimes with dubious practices.
How can you avoid the pitfalls and choose the right installer for your photovoltaic project? Our renewable energy experts give you all the keys to a safe and profitable investment.
Why call in a solar expert?
A photovoltaic system is a long-term investment. To guarantee optimum yield and an attractive return on investment, it' s crucial to choose the right installer and equipment.
- A personalized study : every project is unique. A serious professional will analyze your energy and geographical situation, your needs, and your objectives before proposing an adapted solution.
- Support from A to Z: an expert guides you through administrative procedures, subsidy applications and installation.
- Compliance with standards: a certified installer guarantees a safe, reliable installation that complies with current regulations.
How do you choose a reliable company?
- Choose companies with the "Les Pros du solaire" label. This quality label, issued by Swissolar, guarantees technically and legally compliant installations, as well as professional advice.
- Check references and customer reviews. Before signing a contract, do your research! Check out the company's website, read customer reviews and ask to see previous projects.
A reliable quote starts on site
Beware of companies that offer a quote without visiting your home. An on-site feasibility study is essential for an accurate quote tailored to your home.Â
What should a quality offer contain?
A serious quotation must include several essential elements:
- Work required for solar installation: tinsmithing, roofing, electricity, grid connection (AC).Â
- Administrative procedures: grant applications to Pronovo, declarations to the municipality and the network operator. For your information, an asbestos diagnosis is mandatory for buildings constructed before 1991.
- Warranties: products (≈ 25 years), production and inverters (5 to 10 years).
- Solar grouping costs.
- Beware of quotes with too short a validity period! At SEIC, we recommend a cooling-off period of at least one month. It's essential to take the time to compare offers and make an informed choice.
- Beware of exaggerated discounts or dubious promotions!
Optimize your solar system
To maximize your investment, consider integrating your solar production with other equipment:
- Heat pump and charging station: by coupling these systems with your photovoltaic panels, you increase your self-consumption rate and reduce your electricity bill even further.Â
- Energy storage: a battery can enable you to use your energy even at night, improving your energy autonomy.
So take the time to choose wisely!
A solar project is a long-term investment that requires careful thought and support. To avoid unpleasant surprises:
- Use a certified installer and check his references
- Insist on an on-site survey and detailed estimate
- Beware of overly tempting offers and aggressive commercial practicesÂ
- Compare warranties, panel power and material quality
