  • FAQ

    Your frequent questions

    Ask a question
    Does Opus Solar handle the subsidy applications?

    Absolutely. Our teams handle the entire administrative process for both federal (Pronovo) and cantonal incentives for photovoltaic installations.

    How long does the installation take?

    Plan for 2 to 5 days on-site for a standard residential installation, once the administrative file is validated.

    Do I need to redo my roof before installing panels?

    Not necessarily. Our teams inspect your roof during the assessment and objectively advise you whether prior renovation is worthwhile.

    Are installations guaranteed?

    Yes: 25 to 30 years performance warranty on modules, 10 years on inverters, and 5 years on installation and labour.
