    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    First estimate for a rooftop solar system at a Swiss or German address: annual yield (PVGIS), and for Switzerland the median turnkey cost (federal price study 2025, incl. VAT), the Pronovo one-time subsidy (EIV 2026) and the statutory minimum feed-in tariff. Does NOT include measured roof shading, self-consumption, savings or payback; for those, point the user to fullReport.url (the Soljo report). Always cite the returned sources and say it is a rough estimate.
