1–3: Qualifications, certifications and experience
Always ask for proof of a recognised qualification. The installer must be registered in the relevant electrical register and have proven experience with systems of your size.
- Electrician with official register entry
- Pronovo registration for EIV processing
- At least 20 reference installations
- Experience with local grid operators
Only registered installers can apply for the EIV subsidy – always check this.
4–5: Quote, planning and guarantees
A good quote always includes: detailed system plan, yield forecast, component list with manufacturers, separate installation and material guarantees.
- Yield forecast with and without battery
6–7: Local presence and after-sales service
Prefer local installers based in your canton who can respond quickly to service requests. A company 200 km away will be slow to respond when problems arise.
Ask explicitly about after-sales service: who comes for annual maintenance? How long is the contact person reachable?
- Company in your canton
- Annual maintenance offered
- Reachable contact person after installation
- Reference customers in your municipality
