🟢solar_first_estimate(address, lat, lon, country, kwp, ...)
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.
