What Fronius Solar.Web does
Fronius Solar.Web is a cloud-based photovoltaic monitoring and energy management platform developed and operated by Fronius International GmbH, a privately held Austrian industrial company headquartered in Wels and Pettenbach, Austria, with 5,001–10,000 employees across its Solar Energy, Perfect Welding, and Perfect Charging divisions. The platform connects to Fronius inverters (including the GEN24 and Verto lines) to deliver real-time monitoring of AC and DC voltages, currents, and generation power, along with historical data analysis, consumption tracking, and remote inverter firmware updates. Companion products include the Solar.start onboarding app, the Solar.creator system design tool, the Repowering Tool, and the Fronius Smart Meter, forming a vertically integrated hardware-software-services ecosystem.
The platform operates on a freemium SaaS model: a free Basic tier provides core monitoring and notifications, while Solar.web Premium adds custom reports, ROI analytics, 2-day PV production forecasts (powered by UBIMET weather data), the Energy Cost Assistant for flexible-tariff optimization (aWATTar), the Energy Security Assistant for backup charging, and public display mode. Hardware revenue comes from Fronius inverters and the Reserva Pro battery storage system (12–128 kWh, starting at approximately €6,000). Go-to-market combines a certified installer network for hardware-led distribution with self-service onboarding via Solar.start and direct app-store acquisition, serving residential PV owners as the primary segment, commercial enterprises with scalable storage needs, and solar installers requiring remote configuration tooling across 27 countries spanning Western Europe, Eastern Europe, North America, and Oceania.
